Hi,

I am trying to programmatically (Server side) to filter a rad grid based on combo boxes and radio buttons and before the page loads for the user.

using VB.NET I am using this on LoadComplete (I know this is two different methods, but neither work to an extent).


The first option puts in the value of 0 in that column but doesn't display the results filtered only the entire data source.
The second option just doesn't do anything from what I can tell. (I had to sent LINQ to False as it just errored out as I found out in a previous thread).

Any ideas why this doesn't work? Or how to get it to work please?

Thanks,
Alex

I'm using a RadGrid with the theme Web20 and I'm having trouble changing the color for a specific cell in the RadGrid header. I noticed the header is using an image to create the gradient look, but I need to create the look of a spacer. I was able to accomplish this with the tree list, but I'm having issues doing this with the radgrid. See the pictures attached. 

I'm looking to do this in CSS on inline style or something that doesn't require a reference to System.Drawing in the VS project. Capture1.png below is the radgrid. Capture2.png is the treelist.

Thanks,

Derek

Hi all,

I am working with a RadGrid with a NestedView that has Client row-selecting enabled and has EnablePostBackOnRowClick set to True.  When I attempt to expand a row (either by the Client "RowClick" or by using the expand column), I am handling the ItemCommand event server side to attempt to close any currently expanded rows, and expand only the currently clicked row (like in the "Overview" demo for the RadGrid).  Here is the RadGrid:

And here is the ItemCommand event handler:


If I was to only click on the expand/collapse column to open the rows, I would have no issue and the Grid would behave as I expect.  But if I click on a row (which should expand that Row's NestedView), I see that the following uncaught exception is displayed in my browser's console:

"Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: DataBinding: 'ToString()' is not a valid indexed expression."

If, however, I change AllowRowSelect to be set to False (while leaving EnablePostbackOnRowClick set to True), the program works as I would expect (when clicking the expand/collapse column or clicking the row).

While I could probably work with this, I'm wondering why it is not working when AllowRowSelect is set to True.  (Also, the default styling for the SelectedRow is not applied when AllowRowSelect is set to False).

I'm fairly new to Telerik's controls, so I may be missing something obvious, but thanks for any help/suggestions.

Hi ,

I have two Rad list box . On is the source and the other is the destination. The source list box is bound with data and on transfer to Destination i wanted a jquery event to fire so that the items in the Radlist Destination would refresh the Grid to the those items which are moved from source to destination. For example I Have selected Employee 2 and employee 4 to be moved to destination my rad grid should refresh and display data with employees 2 and 4. Please help me out i am not able to choose the proper even. I have used on client load but it works but it continuously loads without stopping.The page is continuously refreshed.

Thanks in advance.

Hello,

I was wondering if someone could help me here. I have read both this and this but still struggling on what I am trying to do.

Here is my RAD GRID below


Below are the two SQL Data Sources.

The link between them is that the Table "Documents" Column "Doc_CategoryID" should match up to the Table "Customisation" column IDNO and the available choices which the user can select should be displayed from the Table "Customisation" Column "FieldAnswer".

 
The part where it fails to work is when the user clicks the Edit Button on the RadGrid, it just errors out saying this below. I have tried different options in the UniqueName but none of them i have tried is working. Any ideas?  



Thanks,
Alex

Hello,

I am trying to save user preference and load them back again.  I did check this (http://demos.telerik.com/aspnet-ajax/pivotgrid/examples/applicationscenarios/persisting-radpivotgrid-settings/defaultcs.aspx) demo for it and created a test page but I am not able to load a saved state.  So I am able to save a state but after I reset the state I am not able to load it again.  I am missing something but am not sure what it is.  Can you please help me.

Hi
Is it possible to set a max number of columns fields in the fieldswindows?

Hi All, I 'm a matter when using RadGrid and radwindow to
insert/update data from database. I used Formview to add data( controls:
textbox, combobox), but i used two related combox in formview to filter
data , i have  error:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
My codes:
1. combox 1:
<telerik:RadComboBox ID="ddlMaSP" Runat="server" DataSourceID="SqlDsMaSP"

DataTextField="TenSP" DataValueField="MaSP" SelectedValue='<%# Bind("MaSP") %>'

Skin="Office2007" Width ="300px">

</telerik:RadComboBox>

<asp:SqlDataSource ID="SqlDsMaSP" runat="server"

ConnectionString="<%$ ConnectionStrings:PGKH %>" SelectCommand="PGKH_CboMaSP"

SelectCommandType="StoredProcedure">

</asp:SqlDataSource>

2. combbox thứ 2:

<telerik:RadComboBox ID="ddlCTMaSP" Runat="server" DataSourceID="SqlDsCTMaSP"

DataTextField="CTMaSP" DataValueField="IdCTMaSP"

SelectedValue='<%# Bind("IdCTMaSP") %>' Skin="Office2007" Width ="300px">

</telerik:RadComboBox>

<asp:SqlDataSource ID="SqlDsCTMaSP" runat="server"

ConnectionString="<%$ ConnectionStrings:PGKH %>"

SelectCommand="PGKH_CboChiTietMaSP" SelectCommandType="StoredProcedure">

<SelectParameters>

<asp:ControlParameter ControlID="ddlMaSP" Name="MaSP"

PropertyName="SelectedValue" Type="Int32" />

</SelectParameters>

</asp:SqlDataSource>
I get error When i using Autopostback for two comboxbox, but i not
use Autopostback is not error but two comboxbox not related. Thanks all.

When using Internet Explorer on a Windows Phone, when typing the first character into a radmaskedtextbox, the cursor will skip to past the end of the input mask. So if the mask if four characters, after the first character is entered, the cursor will skip to the fifth position. Tested on a HTC6990LVW running Windows Phone 8.
