| | Hi
You need work like this way
Say you have delete column like this way in gridview
[b]HTML [/b]
1. DeleteWhen you are bind data to gridiview , you need set a client side script to your delete link button
[b]C# Code[/b]
2.
protected void CGgrdivewDemo_RowDataBound(object sender,
GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
LinkButton lnkbtnDelete= (LinkButton)e.Row.FindControl("lnkbtnDelete");
lnkbtnDelete.Attributes.Add("onclick", "javascript:return " +
"confirm('Are you sure you want to delete this record " +
DataBinder.Eval(e.Row.DataItem, "PrimaryKeyColumn") + "')");
}
}
When you are press link delete link button it will delete based on your response.but we need do one more step to delete from the Database that record.
To this we can use the Row Command event in gridview.
3.
protected void CGgrdivewDemo_RowCommand(object sender,
GridViewCommandEventArgs e)
{
if (e.CommandName == "Delete")
{
int PrimaryKeyColumnValue = Convert.ToInt32(e.CommandArgument);
// then call the delete method and pass the primakrycolulmvalue to delete that record in db
}
}
That's all.let you try it, if you found any issue let me know.
Thank you | |

| | Hi
Yes validation not happening, when you are click in link button, just client message will come to continue
after that it will validate data and etc.
thank you | |

| | Hi
Then its can't in client side validation, you need use the client side and after perform confirmation from the server. and even if you are press delete button, first client side script will execute, then server side.
According your words now you need server side check something, based on values to need ask confirmation to users.
Even you can't do like windows form validation in asp.net, because client side always first.
YOu need server side action other than client side,Just try with this message box
