//getting key code of pressed key

var keycode = (key.which) ? key.which : key.keyCode;

var intrval = document.getElementById('ctl00_Mdi_grdabc_txtInterval');

//comparing pressed keycodes

if (!(keycode==8 || keycode==46)&&(keycode < 48 || keycode > 57)) {

//Condition to check textbox contains 3 numbers or not

hi,

Seems some issue with the paste.

protected void gvPlanMaintenance_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
TextBox txt= (TextBox)e.Row.Cells[0].FindControl("txtInterval");
if (txt != null)
{
btnTest.Attributes.Add("onkeypress", "javascript:return Validate();");
}
}

hi,

Please Try this.

protected void gvPlanMaintenance_OnRowDataBound(object sender, GridViewRowEventArgs e) {  TextBox txt= (TextBox)e.Row.Cells[0].FindControl("txtInterval");    if (txt != null)   {    btnTest.Attributes.Add("onkeypress", "javascript:return Validate();"); }  }

Hope this will help.
