In InsertItem Template of a FormView, I want to execute a JavaScript on "onChange" event of a textbox. I have written following code for this

{

if (e.CommandName == "New" || e.CommandName == "Edit")

{

TextBox txtStaffName = ((TextBox)myFormView.FindControl("txtStaffName"));
txtStaffName.Attributes.Add("onChange", "dataChanged();");

}

}

The dataChanged() javascript method is running in Edit mode of formview but is not working in Insert mode!!!

The control name in both insert and edit template is the same i.e. txtStaffName

Please help where should i place this code. Or how should i add this attribute with this control.

 Thank you

Hi mrkashifali ,

I strongly suspect whether the javascript is registed to the control.

You can write code in PreRender event instead. And what I want to remind is that the onchange event will fired when mouse leave the control.

    protected void FormView1_PreRender(object sender, EventArgs e)
    {
        if ((this.FormView1.CurrentMode == FormViewMode.Edit) || (this.FormView1.CurrentMode == FormViewMode.Insert))
        {
            //code here
        }
    }

Thanks Samu Zhang, it worked.
