first of all DO not use static. second use a repeater ( if you are using asp.net). here is an exampl of the databound. protected void AdditionalDevice_ItemDataBound( object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item) { var accessDevice = (WcfAccessDevice)e.Item.DataItem; var additionalDeviceDropDownList = (DropDownList)e.Item.FindControl( "additionalDeviceDropDownList" ); var lblDeviceType = (Label)e.Item.FindControl( "lblDeviceType" ); var linePort = (Label)e.Item.FindControl( "LinePortLabel" ); var macRegularExpressionValidator = (RegularExpressionValidator)e.Item.FindControl( "MacRegularExpressionValidator" ); //Set error message macRegularExpressionValidator.ValidationExpression = CompleetApplication.ValidatorInvalidMacAddress; macRegularExpressionValidator.ErrorMessage = CompleetApplication.ValidatorInvalidMacAddressMessage; // get the value of the current user device var currentUserDevice = hfCurrentUserDevice.Value; // Set the two labels lblDeviceType.Text = accessDevice.DeviceLevel; linePort.Text = accessDevice.LinePort; additionalDeviceDropDownList.Items.Add( new ListItem { Text = accessDevice.DeviceName, Value = accessDevice.MacAddress, Selected = currentUserDevice == accessDevice.DeviceLevel }); } } and the code for the itemcommand. protected void AdditionalDevice_ItemCommand( object source, RepeaterCommandEventArgs e) { // set all your asp controls (label, ddl, textbox.etc) DropDownList ddlAdditionalDevicesEdit; try { var submitError = "" ; switch (e.CommandName) { case "Edit" : // hide labels var label = (Label)e.Item.FindControl( "lblDeviceType" ); var portLineLabel = (Label) e.Item.FindControl( "LinePortLabel" ); label.Visible = false ; portLineLabel.Visible = false ; var additionalDeviceDropDownListFromRepeater = (DropDownList)e.Item.FindControl( "additionalDeviceDropDownList" ); additionalDeviceDropDownListFromRepeater.Items.Clear(); for (var i = 0; i { var item = additionalDeviceDropDownList.Items[i]; additionalDeviceDropDownListFromRepeater.Items.Add(item); } // show ddl additionalDeviceDropDownListFromRepeater.Visible = true ; // show textbox var macAdressTextBox = (TextBox)e.Item.FindControl( "deviceMacAdressTextBox" ); macAdressTextBox.Visible = true ; // hide edit_button ((Button)e.Item.FindControl( "additionaldevice_editbutton" )).Visible = false ; // Hide delete button ((Button)e.Item.FindControl( "additionaldevicedeleteButton" )).Visible = false ; // show submit_button ((Button)e.Item.FindControl( "additionaldevicesubmitbutton" )).Visible = true ; // show cancel_button ((Button)e.Item.FindControl( "additionaldeviceCancelButton" )).Visible = true ; // Hide rows wich are not editted foreach (RepeaterItem item in AdditionalDevices.Items.Cast ().Where(item => (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem) && (e.Item.ItemIndex != item.ItemIndex))) { item.FindControl( "additionaldevice_editbutton" ).Visible = false ; item.FindControl( "additionaldevicedeleteButton" ).Visible = false ; } break ; case "Submit" : // get values for updating BW var devType = (DropDownList)e.Item.FindControl( "additionalDeviceDropDownList" ); var macAdressTBox = (TextBox)e.Item.FindControl( "deviceMacAdressTextBox" ); // show labels var devilabel = (Label)e.Item.FindControl( "lblDeviceType" ); devilabel.Visible = true ; // hide dropdownlist and textbox macAdressTBox.Visible = false ; devType.Visible = false ; // Set new selected deviceType and macAdress to labels and validate macAdressTBox.Text = macAdressTBox.Text.Trim().Replace( ":" , string .Empty).Replace( "-" , string .Empty); submitError = CompleetApplication.Validate(Page, "EditScaDevice" ); if (! string .IsNullOrEmpty(submitError)) { // set old values back devilabel.Visible = false ; macAdressTBox.Visible = true ; devType.Visible = true ; // show message ShowFailureTextAddingAdditionalDevice(submitError); return ; } devilabel.Text = devType.SelectedValue; // update the SCAdevice in BW additionalDeviceProfilePasswordTextBox.Text = PasswordLogic.GeneratePassword(2); submitError = App.SaveSharedCallAppearance(_user, devilabel.Text, additionalDeviceProfilePasswordTextBox.Text, macAdressTBox.Text); if (!

Vasant You cannot access the controls in the Static Method for that U need to do have the context of the page then do the find control an then u can do the Rest May be u can do something Like this but better U should use the Jquery for the same if (HttpContext.Current != null) { Page page = (Page)HttpContext.Current.Handler; TextBox TextBox1 = (TextBox)page.FindControl("TextBox1"); TextBox TextBox2 = (TextBox)page.FindControl("TextBox2"); }
