Web Forms :: RequiredFieldValidator Not Working For TextBox?

Oct 4, 2010

I've recently finished building one of my first websites (and CMS) in ASP.NET but have came across a problem where a RequiredFieldValidator isn't working as it should do? I originally created the admin page to not require the RequiredFieldValidator, but now that I do need it the page won't acknowledge it's there. I have even set the field in the database to not accept nulls, but the query will still insert a null value into the database (SQL Server 2008 Express).

The TextBox that I'm referring to is "txtSectionTitle"

Data Controls :: Display DataList Row (Item) Details In TextBox On Button Click

May 7, 2015

I have a datalist control which uses repeatcolunm. I want to make Datalist items clickable and get the clicked item value into a textbox outside the datalist. I did this and it works only when I set "RepeatLayout="flow"" which cancels the "repeatcolunm" which is very necessary in my case. Below is code:

<asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource2" RepeatDirection="Horizontal" ShowFooter="False" ShowHeader="False" RepeatColumns="21" OnItemDataBound="DataList1_ItemDataBound" OnItemCommand="DataList1_ItemCommand" >
<ItemStyle Font-Bold="True" Font-Italic="False" Font-Overline="False" Font-Strikeout="False" Font-Underline="False"/>
<ItemTemplate>
<asp:LinkButton id="SelectButton" Text="select" CommandName="Select" runat="server" style="display:none"/>
