Hi,

I got an application with a ListView containing RadControls in InsertItemTemplate.
I would like to propose to the visitor a value in a RadTextBox calculated on value inserted by this visitor in another RadTextBox.
But how can I get access to these fields in js ?
In .Net code behind no problem.. but I don't know how to do that on client side.

Can someone help me on this ?

Regards,

David

Radwindow not opening in RadGrid button column click event

Hi Telerik Team,

This problem is related with opening a RadWindow. I have a RadGrid with a button column and need to open an Radwindow within its click event (command event). So far, this has not been a problem for me, since I had call the RadWindow mostly in

button click event of a button. (I did it like -- > RadWindow1.VisibleOnPageLoad=true ).

But when I try to do the same thing the window is not shown (pop-up). Can you please tell me the reason?

Note: The reason for me to open/show the RadWindow in code behind using "RadWindow1.VisibleOnPageLoad=true" is, I need to

to do some validations to get the decision whether to open it or do another operation.

Thanks,

Dilip Nilanka

Select Row through Telerik LinkButton and Redirect

Hi -

I'm new to programming... so this might be a simple fix. What I'd like to do is use a linkbutton to select a row of data, put that data into a session variable, then redirect to a page that will display the selected data. Right now I'm trying to figure out how to use the linkbutton to select the row.
Here is my linkbutton

    
            <telerik:GridButtonColumn ButtonType="LinkButton" Text="Select" UniqueName="ButtonColumn">  
        
              <HeaderStyle Width="50px" /> 
        
            </telerik:GridButtonColumn>

There are no onClick properties for the GridButtonColumn. How would I initiate the event from this button?

Next, here is what I have for the behind code... once I can figure out where to put it in an event... but I know I'm missing a lot of the code...

    
                    RadPanelItem SOISearchItem = (RadPanelItem)RadPanelBar1.FindItemByValue("SOISearch");  
        
                    RadGrid soiRadGrid = (RadGrid)SOISearchItem.FindControl("SoiRadGrid");  
        
                    LinkButton linkButton = (LinkButton)SOISearchItem.FindControl("LinkButton");  
        
                    if (soiRadGrid.SelectedItems.Count > 0)  
        
                    {  
        
                      GridItem selectedItem;  
        
                      // grab selected row  
        
                    }  
        
                    Session[Tip.Utility.UIConstants.SoiSession] = soi;  // soi is my class variable  
        
                    Response.Redirect("SOI.aspx");

Here is my Grid, which is a table of what I'm calling SOI data (I have an SOI class in the BO):

    
                                  <telerik:RadGrid ID="SoiRadGrid" runat="server"   
        
                                                AllowSorting="False"

                                                Skin="WebBlue" 
        
                                                AllowFilteringByColumn="False"   
        
                                                AllowPaging="False"   
        
                                                ShowGroupPanel="True">  
        
                                  <ClientSettings Resizing-AllowColumnResize="true" AllowKeyboardNavigation="false"></ClientSettings> 
        
                                  <MasterTableView AutoGenerateColumns="False" PageSize="5">  
        
                                    <RowIndicatorColumn> 
        
                                      <HeaderStyle Width="20px" /> 
        
                                    </RowIndicatorColumn> 
        
                                    <ExpandCollapseColumn> 
        
                                      <HeaderStyle Width="20px" /> 
        
                                    </ExpandCollapseColumn> 
        
                                    <Columns> 
        
                                        <telerik:GridButtonColumn ButtonType="LinkButton" Text="Select" UniqueName="ButtonColumn">  
        
                                          <HeaderStyle Width="50px" /> 
        
                                        </telerik:GridButtonColumn>

                                        <telerik:GridBoundColumn DataField="Tier" HeaderText="Tier"></telerik:GridBoundColumn> 
        
                                        <telerik:GridBoundColumn DataField="Org" HeaderText="Org"></telerik:GridBoundColumn>

                                        <telerik:GridBoundColumn DataField="RequestingEntity" HeaderText="Requesting Entity"></telerik:GridBoundColumn> 
        
                                        <telerik:GridBoundColumn DataField="SubmittalDate" HeaderText="Submittal Date"></telerik:GridBoundColumn> 
        
                                        <telerik:GridBoundColumn DataField="ContactInfo" HeaderText="Contact Info"></telerik:GridBoundColumn> 
        
                                        <telerik:GridBoundColumn DataField="Unredacted" HeaderText="Unredacted"></telerik:GridBoundColumn> 
        
                                        <telerik:GridBoundColumn DataField="Redacted" HeaderText="Redacted"></telerik:GridBoundColumn> 
        
                                    </Columns> 
        
                                  </MasterTableView> 
        
                                  <ClientSettings AllowDragToGroup="True">  
        
                                    <Scrolling AllowScroll="True" UseStaticHeaders="True" /> 
        
                                  </ClientSettings> 
        
                                </telerik:RadGrid>

I want to use the ID column, that is hidden, to grab the soi data.

What other information would be helpful to give out to solve my problem? Did I not explain something well enough?

Also, we are using an Entity Framework, and Visual Studio 2008.

Update Usercontrol from Usercontrol

I am having trouble updating a Control within a UserControl from another UserControl.

Layout;

MasterPage
-Page.aspx
    -ASP:Panel
        -RadPanelBar
            -Items
                -RadPanelItem
                    -UserControl1
                        -RadGrid
                            -Button in CommandItemTemplate (When button command completes needs to update controls within UserControl2
            -Items
                -RadPanelItem
                    -UserControl2
                        -ASP:Panel
                            -ASP:Label (this is the control that needs to be updated.)

I have tried to find the control with;

UserControl uc = (UserControl)Page.FindControl("UserControl1"); But it comes back with a null reference.

Any suggestion or pointers would be great.

RadGrid ItemCommand event not firing after rebind

Hi,
Here is the scenario, 1 have 2 RadGrid on a web page. The first one is linked to a SQLDataSource and nothing on the interface can change the query so i dont have to call Rebind() method. But the second one has a filter combobox control that enable the user to filter the data. So i have a query with some parameters and once the query has changed, i have to call Rebind.

Here's the problem. Both Radgrid has a GridbuttonColumn. When i clicked on the first Grid buttonColumn the event ItemCommand is raised and i can do my stuff. But if i do the same with second grid, ItemCommand event is not fired because of that Rebind method. If i comment my 'RadGrid1.Rebind()' line and test it again ( So i play with the first snapshot of my data ), then the event is fired correctly.

Do i have to do something else after the Rebind method to make the ItemCommand event work properly ?

Thanks for your help !
