INFO: my ASPX page has around 3 update panel

protected void BindGridSubMeter()
{
	ConnectionMRI conMRI = new ConnectionMRI();
	DataSet ds = conMRI.NabersSubMetergetData(ddlBldgId.SelectedItem.Value);
	TextExclusions.Text = ds.Tables(1).Rows(0).Item(0).ToString();
	var _with1 = GridSubMeter;
	_with1.DataSource = ds.Tables(0);
	_with1.DataBind();

}


protected void GridSubMeter_RowEditing(object sender, System.Web.UI.WebControls.GridViewEditEventArgs e)
{
	GridSubMeter.EditIndex = e.NewEditIndex;
	this.BindGridSubMeter();
}

protected void GridSubmeter_PageIndexChanging(object sender, System.Web.UI.WebControls.GridViewPageEventArgs e)
{
	GridSubMeter.PageIndex = e.NewPageIndex;
	this.BindGridSubMeter();
}

{
	TextBox txtMeterIdn = (TextBox)GridSubMeter.Rows(e.RowIndex).FindControl("txtMeterIdn");

	string MeterIdn = txtMeterIdn.Text.Trim.ToString();
