                            CurrentDate.AddDays(1);  
        
                        }

what i need it do do is colour the cells that dont fit into the if statement red is there anything that i can do?

How to do text wrapping in the code behind

I have read in RadControlsAJAXCourseware.pdf that I can do text-wrapping manually using style="white-space: normal;" for a node with long text.
How can I do that in the code behind for all nodes (checking with a loop for example every node text if it is beyond a specific length and applying the style).
Thank you very much!

[Solved] Edit Item in RadGrid stays in EditMode

Hey!

I have a RadGrid that performs a CallBack on Update and Insert. The Code is executed correctly and the Item is updated/inserted in my Collection but on the Client the RadGridItem stays in EditMode. I tried setting item.Edit = "false" at the end of my Insert/Update Method but this did not work and threw an exception.

I'm confused because I thought the default behaviour was for the Item to close after editing. Am I missing something in my RadGrid configuration?

    
            <telerik:RadGrid ID="gridVariables" runat="server" GridLines="None" AllowPaging="True"

Trouble with grid inside multipage tabstrip

Hi.

First at all i describe my scenario.

I have a rad tabstrip with 2 tabs tied to a multipage control with 2 pages.

In the multiplage control i have:

in page 1 is contained a rad grid with sorting and paging but using onneed_datasource event handler and a 100 records page limit

in page 2 i have a html table with a button.

The problem.
when the page first load, i can see both the grid in page1 and the table in page2 when i click each tab in the parent control, but ......

if i click in the grid's pager the "4" to go to the grid's page 4, ( record 301 to 400),
the grid show accurately its 4th page ( record 301 to 400) but the multipage control loses the table and button in its page2,
instead of it i see again the grid, i mean doesnt matter what tab i click, i always see the grid

Any lead of solution for this ?.

How to improve RadGrid initial load time...

Hi all,

Please guide us to improve initial load time of RadGrid databinding.

Our scenario is:

1. RadGrid has 7 bound columns and 33 GridTemplateColumns. (Setting column visible property 'false' for 25 GridTemplateColumns at runtime). So total display columns is 15 only.
2. Rendering data size 500KB.
3. It is taking more than 120 seconds to load data in grid.

here is the sample code:

    
            <telerik:RadGrid  ID="RadGrid1" runat="server" Width="960px" AllowPaging="false" PagerStyle-AlwaysVisible="false" 

               HeaderStyle-HorizontalAlign="center" BackColor="#e8eefa" HeaderStyle-Font-Size="8" 

               AllowSorting="false" >  
        
            <ClientSettings Scrolling-UseStaticHeaders="true" >  
        
                <Scrolling FrozenColumnsCount="2" SaveScrollPosition="false" ScrollHeight ="350px"/>  
        
            </ClientSettings>  
        
            <MasterTableView NoMasterRecordsText="No Matching Record Exists" Name="Master" Width="960px" 
        
                DataKeyNames="PersonLocationId" EnableColumnsViewState="true" TableLayout="fixed" 
        
                >  
        
             <Columns>  
        
                <telerik:GridTemplateColumn UniqueName="PersonSelected"

                </telerik:GridBoundColumn>  
        
                <telerik:GridTemplateColumn uniqueName="Day1" HeaderStyle-Width="35px" ItemStyle-Width="100%" >

Telerik controls with SPDatasource and Sharepoint Designer

Hello,

i want to use the telerik controls (e.g. scheduler, grid, rotator) with sharepoint designer.
I can drag and drop the controls on a sharepoint site.
But i have two questions:

a) is this a proven way to use the controls? Or have i to use webparts?
b) Is there a way to use the SPDatasource to get data from Sharepoint lists with Sharepoint Designer?

Maybe somebody can show me a short way to accomplish b).

I think spd 2007 is the easiest way to implement telerik controls in our sharepoint sites.

Thank you very much.

DataSet with MasterTable and DetailTable

I've got a DataSet with 2 tables that have a relationship between them assigned in the DataSet:

i.e.
DataSet ds = new DataSet();
ds.Tables.Add(customerTable);
ds.Tables.Add(orderTable);
DataColumn parentDC = customerTable.Columns["CustomerID"];
DataColumn childDC = orderTable.Columns["CustomerID"];
ds.Relations.Add("Customer_Orders", parentDC, childDC, false);

My Grid has a MasterTable and DetailTable setup, with the appropriate ParentTableRelation setup.

I was hoping that I could simply set the datasource of the grid to this dataset (the master getting the first datatable, and the detail getting the second), and that the relationship would be used in the DetailTable to filter on expanding, but that does not appear to be the case. Is this possible, and if so, are thre any live examples on the net?

Thanks.
