Hi,

generate OnRowDataBound event for Gridview and write the following code

protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string item = e.Row.Cells[0].Text;
foreach (Button button in e.Row.Cells[2].Controls.OfType<Button>())
{
if (button.CommandName == "Delete")
{
button.Attributes["onclick"] = "if(!confirm('Do you want to delete " + item + "?')){ return false; };";
}
}
}
}

Use below function-

function deleteArticle(hdnPostId, divContainer) {

if (confirm("Are you sure?"))

{

$.ajax({

type: "POST",

url: "TestPage.aspx/DeleteArticle",

data: "{PostId: '" + hdnPostId + "'}",

contentType: "application/json; charset=utf-8",

dataType: "json",

success: function (data) {

$('#' + divContainer).hide();

},

failure: function (errMsg) {

alert(errMsg);

}

});

}

return false;

}

in code behind call like this-

hypDelete.Attributes.Add("onclick","javascript:deleteArticle('"+hdnPostId.Value+"','"+divContainer.ClientID+"');return false;");

Hi,

define one button like this

<asp:LinkButton ID="lbDelete" runat="server" OnClick="lbDelete_Click" OnClientClick="return fnConfirm();"> Deleteasp:LinkButton>

write javascript function for button like

<script type="text/javascript">
function fnConfirm() {
if (confirm("The item will be deleted. Are you sure want to continue?") == true)
return true;
else
return false;
}

in lbDelete_Click event write the logic for deletion of item
