Hello programmers!

I'm building a GridTableView code, which is to show the detail of each record in a RadGridView.

To establish the relationship between registration and the detail table, I add a GridRelationFields keys thereof.

When I run the program (developed in aspx), whenever I click on to expand, I get the error I show in the picture:

Not a issue from telerik

 

 

 

Hi, I have a RadButton that is supposed to open a radwindow when the "OnClientClicked" is fired.  However, the first time this gets fired, nothing happens.  The second time I click on the button...the radwindow opens up.  Am I missing some code?  I am basing this on your demo: http://demos.telerik.com/aspnet-ajax/button/examples/slideshow/defaultcs.aspx.

Here is the code that I have:

I can use a plain old button, and it fires off without a second click, but I would really like to use the radbutton since that will keep my styling the same.

Thanks!

Hi,

I'm displaying a Combobox with multiple item selection by means of a checkbox. Does not allow custom text. The problem is that the default text displays always the first item. Is there any way to display the default text as blank or a custom text (by not setting the 'Allow Custom Text' property to true?)

Thanks.

<telerik:RadComboBox ID="RCBRegion" runat="server" Width="100px"

 

 

 

Text="Select Region" DataTextField="Region" DataValueField="Region"

 

 

 

Skin="Web20">

 

 

 

<HeaderTemplate>

 

 

 

<table style="width: 115px">

 

 

 

<tr>

 

 

 

<td style="width: 115px;">

 

 

 

<asp:LinkButton ID="hlSelectAllRegions" runat="server" Text="Selection" onclick="hlSelectAllRegions_Click" ></asp:LinkButton>

 

 

 

</td>

 

 

 

</tr>

 

 

 

</table>

 

 

 

</HeaderTemplate>

 

 

 

<ItemTemplate>

 

 

 

<asp:CheckBox runat="server" ID="CheckBox1" Text=' <%# DataBinder.Eval(Container.DataItem, "Region")%>' />

 

 

 

</ItemTemplate>

 

 

 

 

</telerik:RadComboBox>

 

is it possible to combine combobox with paging
if yes, can you give some examples of how to do it.

thanks in advance
