.NET Gridview InVB - Enable Or Disable The Textboxes And The Dropdown Listbox If The Row Is Not Selected
Mar 9, 2010I have a Gridview that has a button at the left hand side representing the row number. The Gridview has two textboxes and a dropdown listbox as templates. I would like to enable or disable the textboxes and the dropdown listbox if the row is not selected. I also need to enable or disable the templates depending on what the value is of one of the cells. When the templates are changed, I need to save the changes.
I have been able to get this working in the RowDataBound Sub but not in the RowCommand Sub when the row is selected. provide an example in VB.My current RowDataBoundSub, which does no work is below:
Protected Sub PropGrid_RowCommand(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles PropGrid.RowCommand[code]....

Forms Data Controls :: Check Inside Loop Statement If One Of The Textboxes Has The Same Value
Jan 13, 2011In my application I have panel which has 5 textboxes. I've written several functions for checking each of textbox if the entered value is ok (number, is this number in database, etc.). If error occurrs textbox which caused it has different color of background.
However I wanted to write (add) function which will check if one of the textboxes has the same value as other. The problem is that function is checking blank textboxes, although it shouldn't - I wrote if statement which allows checking only non-blank textboxes but it doesn't work.

Web Forms :: Enable Disable Validator Using DropDownList Selected Value
May 7, 2015I have a dropdown list for the which values are coming from DB. There is one option name OTHER, when I select other the textbox appears. For that Textbox I have made a required field validator. Till here it works fine. But when I select any other option, still it gives me validator errors. It should not happen. It should only give me required field error when the user doesn't fills the textbox on select of OTHER option. Please see the code.
Dropdown and Textbox code:-
<asp:DropDownList ID="ddlGraduation" runat="server" CssClass="txtfld-popup_drp"></asp:DropDownList>
<asp:RequiredFieldValidator CssClass="error_msg" ID="reqGraduation" runat="server" ControlToValidate="ddlGraduation"
ErrorMessage="Please select graduation details" InitialValue="--Select--" SetFocusOnError="true"></asp:RequiredFieldValidator>
<asp:TextBox ID="txtOther" runat="server" CssClass="txtfld-popup_p"></asp:TextBox>
<asp:RequiredFieldValidator ID="reqOther" runat="server" ControlToValidate="txtOther" ErrorMessage="Please specify your qualification"></asp:RequiredFieldValidator>
JS code for hiding and show the textbox when user select and deselect the OTHER option from dropdown list:-
<script language="javascript" type="text/javascript">
function pageLoad() {
$('#ctl00_ContentPlaceHolder1_txtOther').hide();
$('#ctl00_ContentPlaceHolder1_ddlGraduation').change(function () {
if ($(this).val() === "Other") {
