I googled this question in many forms but couldn't find an answer applicable to me also..
I have a list view box in windows forms application and in that I add some items in runtime like the code I shown below:
lvinfo.Items.Add("Script executed successfully in " + dbname + " database");
The same code I am using several times for updates of execution and this works fine when I give the view as list or something else...
And also I am not clearing these items at any point of time in my code..When I googled I could find the answers related to clearing items..
My problem is when I set view property as Details, the text/content in the list view box is not displayed..or it is hidden..
EDIT:
I tried
columnHeader1.AutoResize(ColumnHeaderAutoResizeStyle.ColumnContent);
Any response would be really appreciated..
I guess it is because you haven't add any columns to your list view. In details view you should add at least one column to display your item.Try this before adding your items:
listView1.Columns.Add("myColumnHeader");
Have you created column headers for your ListView as the documentation states:
If your ListView control does not have any column headers specified
and you set the View property to View.Details, the ListView control
will not display any items. If your ListView control does not have any
column headers specified and you set the View property to View.Tile,
the ListView control will not display any subitems.
and
Although columns are only displayed in the details view, subitems
without column headers will not display in either the details view or
the tile view.
Theres also an example further down the page for setting up column headers

i have a c# windows form application, in all tabs inside it, i have a data grid view that display data of a punch machine(ID,IP,Port,Type,Description,Location)
there's no errors, but the problem is sometimes the ID is shown instead of the Description Field,knowing that the ID is hidden in the grid..
So what's the possible problem?
the grid view is filled from a data set through a binding source.
all the grid has the same binding source, all are the same,
and i load the data on the form load.
I have seen that before. I don't know what causes it. It seems to happen only if you hide the first column. I don't know if this is the right way to fix it but I moved the ID column away from the first column. In my case, I put it at the end of the dataGridView and I didn't see this "bug" again.
Hope it helps.
the solution was in a combo box that are binded to the same binding source of the grid..i was filled the "Selected Value" field which is wrong..so simply remove the selected value from the combo box
I am struggling to figure out the correct control to use for a list of predefined jobs in the included form. I currently have a ListBoxControl in the Predefined Job Name group that lists all of the predefined jobs for a marine service shop (i.e. oil change, tune up, etc...). Then, based on the item (i.e. job name) that is selected in my ListBox, I need to display the items that correspond to that job. For example, if oil change is the selected job I need to show 4 quarts oil, 1 oil filter, labor, etc...and so on.
Currently, when I load the form data I have a DAO that retrieves all of my jobs from the database using LINQ to SQL. Then I iterate over the results and put the job names into the ListBox. The problem that I am having is that there is no tag for ListBox items like there is for ListView items. So each time the user selects another item in the ListBox, I have to perform another LINQ query to get the job from the database again so that I can display its' corresponding items. If I could use a ListView and hide the column header I could set the entire job on the tag so that each time the user selects a new item I would have access to the details without having to make another call to the database. Is there a way that I can hide the column header of a ListView without hiding the entire column?
You can set the HeaderStyle member of the ListView to None.
listView1.HeaderStyle = System.Windows.Forms.ColumnHeaderStyle.None;
Checkout the ListView HeaderStyle property. It has the following options:
None
Nonclickable
Clickable
From MSDN:
The HeaderStyle property allows you to specify whether the column headers are visible or, if they are visible, whether they will function as clickable buttons. If the HeaderStyle property is set to ColumnHeaderStyle.None, the column headers are not displayed, although the items and subitems of the ListView control are still arranged in columns
You can also create simple object like ListItem which has two poperties: Text (string) and Tag (object). Then implement ListItem.ToString() and you can use these in the ListBox as well.
You can also check out Better ListView Express component, which is free and allows displaying items in Details view without columns. The advantage over ListBox and ListView is a native look and many extra features.
Easy way is using the ColumnWidthChanging event
private void listViewExtended1_ColumnWidthChanging(object sender, ColumnWidthChangingEventArgs e)
{
if (e.ColumnIndex == 0)
{
e.Cancel = true;
e.NewWidth = listViewExtended1.Columns[e.ColumnIndex].Width;
}
}
I found that if you know for a fact you are not displaying the headers it may be best to set the HeaderStyle property to None, as Rajesh mentions above.
When setting in the .CS when screen initially loads the headers are displayed until screen is fully rendered.
I have a grid view that, on selected index, will populate a details view. If the selected index happens to have multiple IP Address's I want to add additional fields to display them. They don't need to be databound since I know the data. I'm using the code below to create the additional template fields. This is done in the Data Binding event.
This works until I select a different row in the grid view, then no data is displayed in the details view. My theory is that it's trying to bind the data but there are a different amount of values returned from the database than controls to put them in. I guess is there an easier way to do this?
// Check for multiple IP
countIP = devicesDetails_CountIP(devicesDataKey);
if (countIP > 1)
{
TemplateField IPAddress2 = new TemplateField();
devicesDetailsView.Fields.Insert(0, IPAddress2);
}
Recently I came across this question, so here is a link that may be of help for future visitors
Create DetailsView from codebehind
i need to display the list one by one in the same line.
It mean instead of binding the value in the row i need bind it in new column first row value. Is that any control available to view the item horizontally .
i have my data in data table.
I'm not sure if I understand your question correctly but I think what you want to use is a repeater. This way you can use whatever markup you want in the itemtemplate to determine what the layout of your data is when it is displayed to the user. You could do something as simple as <%#Eval("WhatEver")%> and you would get horizontally repeating values of the WhatEver column.
I have been given a mockup that I do not know is possible to code in ASP.NET without being a real html and javascript wizard.
I want a GridView that when a row is selected, the selected row expands and below the selected row a panel of additional information is shown, which would also include another small GridView. The idea is this would all be in-line. So if the user selected row 4, then the additional information would appear below row 4 and then after the additional information the parent GridView would continue with row 5.
Ultimately I would want to do a multi-select type of set up, but first I need to figure out if this is even possible. Also, the solution must be 508 Compliant
The one solution I considered was using only one "column". Then I would put all my fields in the ItemTemplate, and my detail panel content in the EditItemTemplate and instead of selecting the row, set it to edit mode. The problem with this solution is I lose the functionality of multiple columns if I throw everything in one huge ItemTemplate.
Any and all suggestions or ideas are appreciated.
What you're describing would be best fulfilled with a ListView control. It takes a little more templating work to set up than a grid view, but you have much more control over it and you can emulate the look of a GridView. You would set your Selected Item template to contain another ListView (or GridView) thats bound to your detailed data.
I've done this using a gridview inside a ListView and using ajaxcontroltoolkit collapsible panel
Your parent list would be a listview that would have 2 table rows for each item, on the first row your parent column, on the second row use colspan and add a gridview wrapped on a collapsible panel
