Select multiple files at a time using FileUpload control in asp.net

Select multiple files at a time using FileUpload control in asp.net - c#

Here's my code
protected void Page_Load(object sender, EventArgs e)
{
tbusrcompdate.Attributes.Add("readonly", "readonly");
if (!IsPostBack)
{
//using session state
if (Session["userid"] == null)
{
Session["userid"] = "Compliance_Tracker";
lblsessionID.Text = Session["userid"].ToString();
}
else
{
lblsessionID.Text = Session["userid"].ToString();
}
//populating ddlTaskId
string query = "select * from Compliance_Tracker.dbo.tasklistManager where STATUS='1';";
string columnname = "TASK ID";
string datavaluefield = "TASK ID";
obj7.PopulateCombo(ddlTaskID, query, columnname, datavaluefield);
//default values in labels
string query1 = "select top 1 [DESC] from Compliance_Tracker.dbo.tasklistManager where STATUS = '1';";
lblDescOutput.Text = obj7.ExecuteScalar(query1).ToString();
string query2 = "select top 1 FREQUENCY from Compliance_Tracker.dbo.tasklistManager where STATUS = '1';";
lblFrequencyOutput.Text = obj7.ExecuteScalar(query2).ToString();
}
}
protected void ddlTaskID_SelectedIndexChanged(object sender, EventArgs e)
{
string selectedtext = ddlTaskID.SelectedValue.ToString();
string query = "select [DESC] from Compliance_Tracker.dbo.tasklistManager where Compliance_Tracker.dbo.tasklistManager.[TASK ID] ='" + selectedtext + "';";
lblDescOutput.Text = obj7.ExecuteScalar(query).ToString();
}
protected void btnAdd_Click(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
if (fuDocpath.HasFiles)
{
try
{
DateTime now = DateTime.Now;
lbldateStamp.Text = now.ToString("mm_dd_yyyy_hh_mm_ss");
string basicPath = Server.MapPath("~/Uploaded_Files/");
string foldername = lblsessionID.Text + "_" + lbldateStamp.Text;
string folderpath = (basicPath + foldername + "/");
Directory.CreateDirectory(folderpath);
foreach (HttpPostedFile file in fuDocpath.PostedFiles)
{
string filename = Path.GetFileName(fuDocpath.FileName);
string folderpath1 = folderpath + "/";
fuDocpath.SaveAs(folderpath1 + filename);
lblName.Text = lblName.Text+"|" + filename;
lblerror.Text = string.Empty;
}
}
catch (Exception ex)
{
lblerror.Text = "File couldn't be uploaded." + ex.Message;
lblName.Text = string.Empty;
}
}
}
Now , using the above code I am only able to do single selection even though I can upload multiple files totally. So I need to know ,if there's a way to select multiple files at a time using fileupload tool OR will I have to use any other tool?
Here's my aspx code

The actual problem was with IE and after updation Iam able to select multiple files now.
Another problem was with my code actually only one file was getting selected because I didn't get the file name properly. Well , it was with the code actually that in the part where I declared the filename string
foreach (HttpPostedFile files in fuDocpath.PostedFiles)
{
string filename = Path.GetFileName(fuDocpath.FileName);
string folderpath1 = folderpath + "/";
fuDocpath.SaveAs(folderpath1 + filename);
lblName.Text = lblName.Text+"|" + filename;
lblerror.Text = string.Empty;
}
Now, here the main problem was I wasn't getting the proper filename . SO , the mistake was
string filename = Path.GetFileName(files.Filename)
instead of fuDocpath.filename.
Silly mistake fml!!!

This is not exactly the answer for your specific code. But it is an alternative to upload multiple files.
For uploading multiple files, I don't do all this stuff, but there is something called as asp:AjaxFileUpload control for this
<asp:AjaxFileUpload ID="AjaxFileUpload1" ToolTip="Uplaod File" OnUploadComplete="AjaxFileUpload1_UploadComplete" runat="server" />
Code Behind :
protected void AjaxFileUpload1_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
{
try
{
string str = System.IO.Path.GetFileName(e.FileName);
string fullpath = Path.GetFullPath(str);
string str1 = "Your insert Query";
con.Open();
cmd = new SqlCommand(str1, con);
// your command parameters to add
cmd.Parameters.AddWithValue("#Image_Caption", str);
cmd.Parameters.AddWithValue("#Image_Path", "Images/" + str);
cmd.Parameters.AddWithValue("#Image_Name", str);
cmd.ExecuteNonQuery();
con.Close();
string filePath = Server.MapPath("~/Images/") + System.IO.Path.GetFileName(e.FileName);
AjaxFileUpload1.SaveAs(filePath);
}
catch (Exception eep)
{
throw;
}
}

it is working fine when i am uploading small files, it through an error when i uploading large file.
Error:" Maximum request length exceeded "
Please, help me how to resolve issue.

you can define max request length in SharePoint like this:
https://blogs.technet.microsoft.com/sammykailini/2013/11/06/how-to-increase-the-maximum-upload-size-in-sharepoint-2013/
In Central Admin>Application Management>Manage Web Applications> Select the desired web app and click General Settings on the ribbon
In web.config edit httpRuntime Node like this (for 2GB files and unlimited execution):

background image disappears after using button in postbacktrigger of update panel in asp.net

It looks like you probably just need to call that JavaScript function that initializes your "Background Stretcher" on each UpdatePanel update (rather than just when the DOM loads). Changing that function to this should do the trick:
function pageLoad() {
$('BODY').bgStretcher({
images: ['images/slide-1.jpg'],
imageWidth: 1600,
imageHeight: 964,
resizeProportionally: true
});
}
Notice that I used function pageLoad() { (should be called on each postback, including AJAX partial postbacks) rather than $(function () { (only called once, when the DOM loads).

add a onclientclick to gridview pager

Using asp.net and the gridview control with the pager.
How do I add a onclientclick to it, So that it will only page once the onclientclick returns true.
Is this possible as it can be done with a link?
i know I can do this
GridView pager page buttons accessibility
myGridView.Attributes.Add("onClick", "setOKToClose();")
but it addes it to the grid and I want it only added to the pager
Thanks

Convert your pager to template but you will have to make your own logic for showing and managing page index.

Onlink button now you can add onclientclick

This link has a correct answer combined with this answer.
Be sure to add a <asp:ScriptManager runat="server" /> tag in your document. Add the javascript in the page header section.
function pageLoad(sender, args) {
//Your jquery code
}
Excellent reference can be found in $(document).ready() and pageLoad() are not the same!
Cheers!

add to GridView RowDataBound
If e.Row.RowType = DataControlRowType.Pager Then
e.Row.Attributes.Add("onclick", "js_function()")
End If

Hide/show table in gridview on button click event

I have project on recruitment.In this project, at one form I have a grid view which contains details of all vacancies. Along with this there is button. When user clicks on this button, available interview schedule for that particular vacancy will be visible in another grid below that row. What I did is I have placed grid view inside table and table is initially invisible. When user clicks on the image button, at that time I tried to find table from the grid view but it can not be found.
Here is the code of my .aspx page
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">

Please show me my problem...

You have provided too much code, that can't be read easily. You have to narrow it down to a specific point.
Let me try to help you on your specific problem.
If you set the control visible=false it will not render at client side and you can't make that control visible later on in client side. Have a look at this similar thread to get an idea how to proceed: Want to make the visibility true from client side of the control which made invisible from server side
