I am currently working on updating a C# project that makes use of WinForms. One of the minor changes I want to make is as follows.
The project has a Form that currently allows the user to click a Button, which then opens a Folder Browser window where they can select a folder for the project to retrieve information from. The selected directory is entered into a TextBox after being selected. However, clicking on the TextBox also opens up a Folder Browser window. You are also currently unable to manually enter text into the TextBox.
What I want to do is (hopefully) pretty simple: I want the user to be able to enter a directory manually into the TextBox and for the project to accept that text input, and for the TextBox to not open a Folder Browser form upon being clicked.
Some other things to keep in mind:
I am not familiar with all the ins and outs of WinForms, so I could very well be missing something simple that I could do.
I am also in the process of completely restructuring the project, so if this is not possible in WinForms, but is possible in, say, WPF, that would not be a major obstacle for me in this case.
Here is the code for the Button, or at least the pertinent part, as a reference. txtProjectDir is the TextBox in question. Not much else is done with the TextBox in the code except for this part.
private void btnBrowse_Click(object sender, EventArgs e)
{
if (chooseProjectFolderDialog.ShowDialog() == DialogResult.OK)
{
clbConvertProjects.Items.Clear();
clbProjects.Items.Clear();
txtProjectDir.Text = chooseProjectFolderDialog.SelectedPath;
cur_projDir = txtProjectDir.Text;
Update: I have made some changes based on the input of several users (thanks to all of you, by the way). This is what the pertinent part of the code looks like now:
private void btnBrowse_Click(object sender, EventArgs e)
{
if (chooseProjectFolderDialog.ShowDialog() == DialogResult.OK)
{
clbConvertProjects.Items.Clear();
clbProjects.Items.Clear();
cur_projDir = txtProjectDir.Text;
I also had to change the TextBox to not be read-only, as well as remove a reference to the above method from its Event properties. Now it is able to accept user input, and doesn't open a Folder Browser when clicked into.
The only problem is this: if I only enter text directly into the TextBox, instead of selecting a folder via the browser popup, the program doesn't seem to properly accept the input (i.e., no information is being collected from the directory). Obviously, I still need to make the program accept user input, as it currently doesn't.
Update 2: After more suggestions (again, thanks guys) and good old trial-and-error, I have re-inserted the line txtProjectDir.Text = chooseProjectFolderDialog.SelectedPath; as removing it from the method had undesired effects on the program's functionality. I am still having an issue with the program accepting the user's manual input into the TextBox, though.
Update 3: As per #blaze_125's recommendation, I am going to have to create a new event for the TextBox when the user Leaves it. Thank you all for the help, I appreciate it!
However, clicking on the TextBox also opens up a Folder Browser window.
The only event for the TextBox is Action -> Click, which is set to btnBrowse_Click
What I want to do is (hopefully) pretty simple: I want the user to be able to enter a directory manually into the TextBox and for the project to accept that text input, and for the TextBox to not open a Folder Browser form upon being clicked.
If you don't want that event(aka action->click) to happen, then you must remove the text btnBrowse_Click from that textbox and leave it blank. That will remove the event you currently have linked to your textbox click.
There will be an even linked to the text box txtProjectDir to check this select the text box and in the properties select the lightning bolt.
I would assume that the even is a click into the textbox however.
If this is the case you probably want to remove this.
Now in terms of how to accept what is in the text box as the value you just want to reference the text and that is in the textbox whitch would be txtProjectDir.Text
private void btnBrowse_Click(object sender, EventArgs e)
{
if (chooseProjectFolderDialog.ShowDialog() == DialogResult.OK)
{
clbConvertProjects.Items.Clear();
clbProjects.Items.Clear();
cur_projDir = txtProjectDir.Text;

On a C# project, I have a "SerialConnectorView.xaml" file that describes an interface with some components.
I added the "Clear all fields" button, called "DoClear" in the xaml. In the file "SerialConnectorsViewModel.cs" I added the "public void DoClear()" method that fires when I click the button. You can see the contents of DoClear() below.
Then I have a "SerialDataView.xaml" file that contains the TextBoxes that display the data.
SerialDataView.xaml and SerialConnectorView.xaml are loaded to the mainview.xaml. The main window looks like the following (there are other components loaded too that don't matter for this):
This is my DoClear method.
public void DoClear()
{
//Clear all the textBoxes
SerialDataView test = new SerialDataView();
test.DataViewParsed.Clear();
test.DataViewHex.Clear();
test.DataViewRaw.Clear();
MessageBox.Show("Still not able to clean the text fields damn it!");
}
The project runs and most things work properly. When I click the "Clear all fields" button the MessageBox shows up but the TextBoxes are not cleared. I don't have any experience with C# but I thought it wouldn't be that hard to clear some textboxes. Well, it's hard for me.
Any suggestions on how I can clear those textboxes on each press of the clear button on the file setup I described?
TIA.
I am designing an application using RibbonReportDesigner, which will let the user to create his own report template. That app will be a part of bigger application.
When user will save template I need to obtain result of Command Property (it is set on the button in designer as "SaveFile"). Why do I need this? I want to check if user really saved that template- if yes then i have to save report name to database. One of the problems is that the event of button click is executed before the dialog opening and i don't know how to check result of saving template.
How can I achieve this? I don't see in designer any appropiate events, which could be usefull for my purposes.
Code, which I use to fire event of saving file:
private void commandBarItem32_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
{
var result = commandBarItem32.Command.Equals(DialogResult.OK);
if (result == true)
{
//create object- report name etc. and save it to database
}
}
The reason I need to save it is that in bigger application there will be combobox with a list of created templates.
You dont need to hook all UI events,
it is much easier to just replace the ReportStorage (list, save, load report layouts)
ReportStorageExtension.RegisterExtensionGlobal(new MyCustomStorage());
where MyCustomStorage implements all CRUD methods to manage the layouts.
For more details you can follow the documentation
I have a C# project (Win Forms), where a form reads an external text file, and then puts the text in a textbox on the form. What I would like to do is create a hyperlink from the text that the program reads in.
For example, if the text file reads "To go to Google, click HERE [www.google.com]", then I want the program to make "HERE" clickable, and go to www.google.com if HERE is clicked on.
Right now the program can read in the text file and recognize the web address just fine. I just don't know how to make "HERE" clickable.
Note: Due to external factors, I cannot make a button, or LinkLabel, or other object for the user to click on. The word itself has to be the hyperlink (if that is at all possible). Also, I have to read the string from an external file. I can't simply put textBox1.Text = "To go to Google, click HERE [www.google.com]";
Thanks in advance!
The easiest work-around for what you are looking for would be to add a handler for DoubleClick, and then just compare the selected text.
If it must be a single click, you want to use OnClick, and then get the test up to the last space to the left and to the right, and do the same compare.
VERY HACKISH btw.
private void textBox1_DoubleClick(object sender, EventArgs e)
{
if (string.Compare(textBox1.SelectedText.Trim(), "HERE") == 0)
System.Diagnostics.Process.Start("http://www.google.com");
}
Building on the previous response, you might want to add an eventhandler to a label instead. You should be able to format the label to be blue and underlined to look like a link, also.
I am working on a C# application which consists of some context menus that have an ability to communicate with my website via WebClient(). The options work when they are clicked.
Once my app is opened, it stays open in the tray and it doesn't show in the taskbar/toolbar (the bar in the bottom where open programs stay). It's basically a background application that runs continuously.
There is a section in the context menu named Upload which includes Upload from Computer and Window screenshot. These are the two items that I want to be accessed via keyboard shortcuts. It shouldn't matter where the user is, once he clicks the set keyboard keys, he will trigger the application's _Click event for a certain context menu.
Final question: How do I make global keyboard shortcuts to trigger some context menus item _Click event?
It would be good is someone could explain a bit more broadly how to achieve this. I'm into C# for a short time (1 month learning it, 2 weeks using it) and I am having trouble understanding code just pasted here.
This is one of the click events I want to associate with a keyboard shortcut:
private void menu_upload_file_Click(object sender, EventArgs e)
{
DialogResult dialogOpened = openFileDialog1.ShowDialog();
if (dialogOpened == DialogResult.OK)
{
string filename = openFileDialog1.FileName;
this.sendToIMGit(filename);
}
}
Thanks.
You will need to use a 'keyboard hook' to create a global hotkey.
See this question.
I am working on Windows Form Application and have created a TextBox control and a Browse button control, so that user can select a folder through Button and show directory in TextBox.
I want to give a freedom to the user to paste a directory path directly into the TextBox. However, at the same, user must provide only a valid directory as a string/text in TextBox.
In addition, I want to disable editing this directory either by keyboard or any other possible way. The user will be able to paste a new valid directory anytime but can't edit it in the TextBox.
Is there any way to do this using C# at runtime?
Thanks.
If you set the textbox to ReadOnly then that stops editing the TextBox.
Then add an event for KeyDown you can capture if Ctrl + V is pressed and then action based on that using the Clipbboard class and if the directory is valid set the TextBox.Text.
private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
if (e.Modifiers == Keys.Control && e.KeyCode == Keys.V)
{
var clipboard = Clipboard.GetText();
if (Directory.Exists(clipboard))
textBox1.Text = clipboard;
}
}
I want to give a freedom to the user to paste a directory path
directly into the TextBox. However, at the same, user must provide
only a valid directory as a string/text in TextBox.
In addition, I want to disable editing this directory either by
keyboard or any other possible way. The user will be able to paste a
new valid directory anytime but can't edit it in the TextBox.
Isn't it contradictory ?
Why don't you use two text boxes then ? First for user to input/paste, with onchange event catching that calls a method that checks the directory's path is correct. If it is, the method copies it to the second text box, not editable, that is also linked to your directory browser.
You could handle the TextChanged event and check to see if the folder is valid and accessible there; if it's not, undo their change. This might not be practical if they can edit the textbox text, as it'll check to see if the folder exists after every keystroke and so typing anything new will be impossible. This might be how you want it to behave however!
To do the checking if the path is valid, I'd use Path.GetFullPath - pass it your textbox text and it'll throw an exception if the path doesn't exist/isn't valid/you don't have permission to access it.
If this feels a bit messy to you, instead of giving them the ability to edit the textbox, you could have a button that sets the text from the clipboard using Clipboard.GetText() and then performs your checks.
Thanks all for suggestions and answers.
Here is something that I did and worked like a charm for me.
I hope, this will help later for someone if face the same problem.
It is the modified version of the original code posted here by LukeHennerley. Thanks LukeHennerley for that.
private void txtBoxTargetDir_KeyDown(object sender, KeyEventArgs e)
{
if (e.Modifiers == Keys.Control && e.KeyCode == Keys.V)
{
var clipboard = Clipboard.GetText();
if (Directory.Exists(clipboard))
{
txtBoxTargetDir.Clear();
txtBoxTargetDir.Text = clipboard;
txtBoxTargetDir.ReadOnly = true;
}
else
{
txtBoxTargetDir.Clear();
txtBoxTargetDir.Text = "It's not a valid directory. Please provide a valid directory.";
}
}
}
You will have to add this event in Form.Designer.cs first.
