I'm having trouble figuring this out and it shouldn't be too difficult. I want to populate my textbox from my database or from the label (The labels are pulling the information from the database already, so essentially copying what's in the label to the textbox). I'm using a GridView and here is the code that I've been trying:
C#:
for (int i = 0; i < GridView1.Rows.Count; i++)
{
TextBox timeR = GridView1.Rows[i].FindControl("rTime") as TextBox;
Label timeRL = GridView1.Rows[i].FindControl("labelRunScore") as Label;
if (timeR.Text == "")
{
timeR.Text = timeRL.Text;
}
}
.aspx:
<asp:TemplateField HeaderText = "Run Time">
<ItemTemplate>
<asp:Label ID="labelRunScore" Visible="true" runat="server" Text='<%# Eval("rTime") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Run Time">
<ItemTemplate>
<div style="display:none"> <asp:TextBox ID="rTime" runat="server" type="number" Text='<%# Eval("rTime") %>' ></asp:TextBox></div>
<input onblur="document.getElementById('<%# ((GridViewRow)Container).FindControl("rTime").ClientID %>').value = this.value"
type="number" style="width: 100px; height: 31px;" />
</ItemTemplate>
</asp:TemplateField>

I am facing a kind of weird problem.
Problem:
When I click a link button inside a grid view then RowCommand event of a grid view is getting fired when deployed on a localhost but not when deployed on the IIS i.e. client system. I have also tried a link button inside grid view but that's also not getting fired.
Solution: (Temporary)
When I disabled ValidateRequest on the top of the .aspx page. It worked.
What should I do?
So what can be the possible solution for it? I have googled but nothing good came up.

It sounds like your page is trying to submit what it thinks is potentially dangerous content if setting the ValidateRequest = false solves the issue. Is it possible that one of the controls on your page is sending html or something like that?
If one of your controls needs to send HTML then you can overcome this by adding an attribute to your model.
[AllowHtml]
[Required]
public string article_content { get; set; }
This will allow html to be entered into the control.

Please try below,

{
if (e.Item is GridFooterItem)
{
GridDataItem item = (GridDataItem)e.Item;
TextBox txtdebit1 = item.FindControl("txtdebit1") as TextBox;

TableCell cell = (TableCell)txtdebit1.Parent;
CompareValidator val = new CompareValidator();
val.ControlToCompare = txtcredit2.ID;
val.ControlToValidate = txtdebit1.ID;
val.Operator = ValidationCompareOperator.LessThan;
val.Display = ValidatorDisplay.Dynamic;
val.ErrorMessage = "Error message";
cell.Controls.Add(val);
}

It would be easy
Activate "AllowPaging" in your GridView.
Make Paging row invisible.
In every click of an icon increase "PageSize" for expanding or click of another icon decrease "PageSize" for collapsing.
I have a GridView inside an UpdatePanel and use javascript to toggle the visibility of a row when the user clicks on an expand button. There is quite a bit of information above the GridView, but I want only the information in the respective UpdatePanel to update so that the screen will stay as is, but the JavaScript call is causing an entire screen refresh and the window jumps back to the top.
The code I'm using for the GridView actually comes from the ExtGridView control on CodeProject (http://www.codeproject.com/Articles/12299/ExtGridView) - it turns the last asp:TemplateField of a GridView into a new row beneath the other items.
I'm new to JavaScript and fairly new to ASP.NET, so I may be missing something simple. Is there a way to keep the JavaScript refresh to just the respective UpdatePanel that caused it?
Here is the JavaScript code:
<script type="text/javascript">
//<![CDATA[
function TglRow(ctl)
{
var row = ctl.parentNode.parentNode;
var tbl = row.parentNode;
var crow = tbl.rows[row.rowIndex + 1];
var ihExp = ctl.parentNode.getElementsByTagName('input').item(0);
tbl = tbl.parentNode;
var expandClass = tbl.attributes.getNamedItem('expandClass').value;
var collapseClass = tbl.attributes.getNamedItem('collapseClass').value;
var expandText = tbl.attributes.getNamedItem('expandText').value;
var collapseText = tbl.attributes.getNamedItem('collapseText').value;
if (crow.style.display == 'none')
{
crow.style.display = '';
ctl.innerHTML = collapseText;
ctl.className = collapseClass;
ihExp.value = '1';
}
else
{
crow.style.display = 'none';
ctl.innerHTML = expandText;
ctl.className = expandClass;
ihExp.value = '';
}
}//]]>
</script>

Well shoot... a little more playing around with the ExtGridView code and I figured it out. The expand/toggle button that calls the javascript also had an HRef assigned, acting as a link, so when it was clicked it would not only call the JavaScript but also acted as if a link was clicked, causing the page refresh.
The culprit code from the ExtGridView:
// ...
else if (RowType == DataControlRowType.DataRow || RowType == DataControlRowType.Footer)
{
_expCell = new TableCell();
_ctlExpand = new HtmlAnchor();
//_ctlExpand.HRef = "#"; -- Commenting this out worked!
_ctlExpand.Attributes["onclick"] = "TglRow(this);";
_ihExp = new HtmlInputHidden();
_ihExp.ID = "e" + this.DataItemIndex.ToString();
_expCell.Controls.Add(_ctlExpand);
_expCell.Controls.Add(_ihExp);
}
if (_expCell != null)
{
_expCell.Width = Unit.Pixel(20);
Cells.AddAt(0, _expCell);
}
I am using Gridview and using Item Template text box. There are 5 text box and i am adding a new row dynamically on clicking on add row btn. in that row i have adding all text box which is empty. Now i want to validate that text box on btn click next.
now to do it?
I used required field validation its working for first time showing text box but when i am adding a new row text box its not causing the validation, I think there is some other way to give validation for dynamically added text box.
How could i validation my all dynamically added text box

You have used the validation group's ValidationGroup="a" on your Next button, but you have not used that on the Required Field Validator. But you have used it in the Email validator.
You have to be consistent with the Validation control and whether to put validation on all controls and button controls for it to work.
<asp:Button ID="btnNext" runat="server" ValidationGroup="a" CausesValidation="true" Text="Next" class="next btn" onclick="btnNext_Click"/>
I think you should start a new page and test with a much smaller case scenario and get that working first. Then add more boxes.
If you still need help with that smaller page, post it for help - it will be easier for us to understand it.
