I trying to search the javascript as a option but my control are in DataGridview,
javascript function is:

var x;
function myFunction()
{
// var x = document.getElementById("suggchangeback");
//x.value = x.value.toUpperCase();

x = document.getElementById(document.getElementById(suggchangeback.ClientID)).value;
x.value = x.value.toUpperCase();
document.getElementById(document.getElementById(suggchangeback.ClientID)).value = x.value;
//return x.value;
}

I am using following script and calling it on onblur="myFunction()"

<asp:TextBox ID="suggchangeback" runat="server" TextMode="MultiLine" EnableViewState="false" AutoPostBack="false" OnTextChanged="suggchangeback_Leave" onblur="myFunction()">

but flow control not going there.

and I want to store var x value from javascript function into the variable on .cs file. How to do this? please help.. or should i have to ask new question?

The most likely cause is that you're binding the grid every time the page loads, and you've forgotten to wrap that code in an if (!IsPostBack){ ... } block.

But since we can't see your code, there's no way to be sure, and no way for anyone to help you.

Solution 1

Rather than taking onlick event, Try OnRowCommand event for button of Gridview.

its not executing OnRowCommand event,means after click on button it not goes onOnRowCommand at code behind

Have you declared that event in GridView?
