I am using a nested Gridview(I have 5 Nested Gridviews). I have applied a Regular Field validator for these Gridviews.
But once I click the button, commas are generated in the textbox. Due to that whenever I click the button, all the validation get fired.
I have researched lots of articles but have not found one related to this.
Here is the image for the Gridview with the commas generated in the textbox:

Question :
1. How do I remove the commas from the textboxes?
2. Reason for these commas? (Why are the commas being generated on the button click?)
3. Limit for the Nested Gridview ?
Any help will be appreciated.

When you have duplicate form field names, the values are concatenated together with commas.
So, for example, if you have the following..
<input type="text" name="name" value="">
<input type="text" name="name" value="">
.. your resulting value on Request.Form postback looks like this:
name=,,
That's what's happening.
Here are a few possible solutions to your problem, though I have not tested any of them :)
1) UpdatePanel
From reading, it seems that if you create an UpdatePanel for the offending grid control (<asp:TextBox ID="txtQty" runat="server"></asp:TextBox>) , it removes this problem. Again, I have not tested this
2) Changing DataBind() behavior during Page_Load()
So...
page_load()
{
if(!isPostBack())
{
// DataBind normally
myGridview.DataBind();
}
else
{
//Some intelligent way to remove commas before binding
}
}
... But that doesn't change the fact that the ,,,values are being posted in the first place. And so, if your primarily concerned with the end aesthetic and not behavior, you can just use JS to strip out the commas (as previously suggested hinted at.)
3) JS - Get Rid of the Commas:
(as suggested here)
<script type="text/javascript">
$("[src*=plus]").live("click", function () {
$(this).closest("tr").after("<tr><td></td><td colspan = '999'>" + $(this).next().html() + "</td></tr>")
$(this).attr("src", "images/minus.png");
$("input", $(this).closest("tr").next()).each(function () {
this.value = this.value.substring(',', '');
});
});
$("[src*=minus]").live("click", function () {
$(this).attr("src", "images/plus.png");
$(this).closest("tr").next().remove();
});
</script>
Hope this helps :)
[Edit] - Validation
I would fire off validation using the .keydown() event. In your case, it might look something like this:
// Bind to each input with id='txtQty', in each row, in the "gridview" with id='gvWarehouseDetails'
$("#gvWarehouseDetails tr input[id*='txtQty']").each(function () {
$(this).keydown(function (event) { // <-- specifies the specific input
// Validation logic goes here...
});
});
The Ajax Control Toolkit is a viable solution, however support for it has become non-existent. I'm assuming there is a level of dynamic control on that field. In essence, the grid will display it at certain instances?
Either way, you could add a specific class to the field:
<asp:Textbox id="txtContent" runat="server" CssClass="Validator">
Essentially when the grid adds all of these fields to your page, they'll all have the Validator class. So you can write JavaScript to actually strip the character out of the field, example:
$('.Validator').on('blur', function() {
$(this).replace(',', '');
});
As soon as the focus changes, that field will remove the , from the field as soon as the mouse leaves the , will be removed from the field.
That is one approach, countless other options do exist as well to accomplish this. This solution is pretty easy, agile, and light so it should be adequate.
Update:
The solution I chose shouldn't require a loop over those fields. Simply because blur triggers whenever a change or focus is lost on that field. Since you mentioned the , appears when the user clicks in the field. Otherwise you could do validation on all the fields. All you simply would need to do:
$('.Validator').each(function() {
// Will iterate through each field.
});
So you could essentially use JavaScript yourself to validate those fields, or use a simple library such as Valid8 which will do all client-side validation. No postback, all done client side before sent to the server to process.
Avoid:
