I have a button which is not working when placed below two panels. If I move it above the panels, it works.
It works either way in Firefox. It does not work in IE 8
The button runs this code
protected void Button2_Click(object sender, EventArgs e)
{
panelForm.Enabled = true; //input panel
panelOutput.Visible = false; //output panel
Button1.Visible = true; //input panel button
}
I have some workarounds, but was hoping to find the cause of the issue.
edit: here is the markup of the second panel and button. I've tried moving the button outside of the panel and get the same result.

The problem is that you are using a <form> tag within your content page. The master page already includes a <form> tag and IE appears to be balking at the form within a form. When I removed the <form> tag from your aspx, the button handler ran under IE8.
The sample code is Button2_Click, but your button markup outside of the panels has test_button_Click as the event handler? There are three buttons, so which one are you asking about, I assume the last?
I noticed that you have a tag inside your first panel (panelForm). Also, I don't see a a tag with a runat="server" attribute (although, it could be in a master page). And it doesn't look like your button is inside a form (unless the master page has a form).
The problem is that you can only have one form on a page in Asp.NET WebForms. If you don't have any <form runat="server"> tags on your page, then you buttons will not fire any events on the code-behind.

Why can't I use the (input) I put in my (list view) in the C # code field?
<asp:ListView ID="ListV" runat="server">
<ItemTemplate runat="server">
<asp:Label ID="Label2" runat="server" Text="Label"></asp:Label>

<td class="col-2">
<asp:Button ID="delete" CssClass="btn btn-outline-danger" CommandArgument='<%#

</td>
<td>
<input id="quantity2" runat="server" type="number" value="1" min="1" max="20" />
</td>
</tr>
</ItemTemplate>
</asp:ListView>
You want a server control there. Additionally, this control only exists as part of an item template, meaning there isn't just one control named quantity2... there could be many, depending on the data source. Therefore referencing it just by name is not good enough. And speaking of data sources, depending on how you handle this the databinding may not have taken place yet at the time the Page_Load code runs, meaning the input control doesn't exist at all.
So the real question is: what do you want to do with this input?

I have not done any databinding also. Please help me out, if I missed out something.
Your problem is about your css styling. If you remove inline css styles from your divs you can click them.
Those divs are displaying on top of each other without proper styles and radiobuttons stay under another div, prevents you clicking on them.
Or if you want to keep the styles and still click them you can use "z-index" attribute with adding z-index:1;, so you bring the div with radiobuttons, above the other div, making them clickable.
....
<div style=" position:relative; top:10px; left:-172px; z-index:1;">
<asp:Label ID="Label9" runat="server" Text="Select an option: "></asp:Label>
<asp:RadioButton ID="rb1" Text="Colect" AutoPostBack="true" runat="server" GroupName="rboption"/>
<asp:RadioButton ID="rb2" Text="Deliver" AutoPostBack="true" runat="server" GroupName="rboption"/>
</div>

I hope you are coding well,

Now as per the business requirement, I need to show a thumbnail of the Image that user uploads, and for .psd file I have a standard icon which I display's at the run time, in the code behind I am validating the file extension to be the .psd file and it is then display the psd icon, I am trying to set the ImageURL for
protected void pdfFile_UploadedComplete(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e)
{
if (Path.GetExtension(e.FileName).ToString().ToLower() != ".psd")
{
string alertMsg = #"alert('Please provide .PSD type file');";
ScriptManager.RegisterStartupScript(this, this.GetType(), "Test", alertMsg, true);
//pdfFile
}
else
{
imgThumbNail.ImageUrl ="~/images/psdIcon.jpg";
}
}
The problem is that Panel doesnt gets update at the run time, even the page source shows src="". I am suspecting that its a Update Panel issue.
Kindly point me into the right direction.
Thanks in advance
FileUpload can not be done Asynchronously. In order to do that PostBackTrigger Trigger will be required to upload.
I have a drop-down list which gathers data from the database and a textbox which contains the text from the drop-down list when I select a value from the drop-down list.

CS Code:
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
TxtOption.Text += DropDownList1.SelectedItem.Value;
}
The DropDownList is wrapped in an UpdatePanel, but the TextBox is not.
What this means is during the asychronous postback (triggered on the SelectedIndexChanged event), the postback only has visiblity of the controls inside the UpdatePanel (as this is all that gets submitted to the server).
Because the TextBox is outside the UpdatePanel, it does not have visibility of it during the async postback.
The easiest solution would be to put the Textbox inside the UpdatePanel.
Another solution would be to use ScriptManager.RegisterStartupScript to set the value of the control from the SelectedIndexChanged event using basic JavaScript (which has access to the entire DOM, unlike the asynchronous postback).
E.g
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
ScriptManager.RegisterStartupScript(UpdatePanel1,
this.GetType(),
"NameOfScript",
string.Format("document.getElementById('{0}').value = '{1}';",
txtOption.ClientId,
DropDownList1.SelectedValue));
}
I have a fileupload control with an updatePprogress in an updatePanel like this:
UpdatePanel is: updExtraSmall
<Triggers>
<asp:PostBackTrigger ControlID="lnkExtraSmall" />

</DIV>
</ProgressTemplate>
</asp:UpdateProgress>
</td>
</tr>
</table>
</ContentTemplate>
and:
function showWait()
{
if ($get('fupldExtraSmall').value.length > 0)
{
$get('UpdateProgress1').style.display = 'block';
}
}
The problem is that the updateProgrss doesn't show.
Can anyone help me please?
Thank you,
Alina
Just Use the asyncfileupload control which come with ajaxcontroltoolkit 3.0 and then upload the file.
Put the UpdateProgress outside the ContentTemplate.
