[Solved] Display dynamic Image for Boolean column data instead of using GridCheckBoxColumn

Hi -

I would like to use an image as a boolean indicator (e.g. "off.gif" and "on.gif") instead of using something the GridCheckBoxColumn. Is there a solution that somebody has already done for this? I couldn't find one searching this forum and I would think its not a unique usage of a boolean flag.

I know one solution can be a template column with an <asp:Image> and we can swap out the image source in the proper code event, but we have a lot of places to use this pattern in multiple grids/pages and would like to figure out some way to encapsulate it.

Thanks!

hitting spacebar in node text boxes selects the root node

Hi, I have a tree with templated nodes. Each node contains a few text boxes. When a text box is selected and the spacebar is hit, the root node is immediately selected (no matter where I am working on the tree), and no space is put into the text box that has focus. This happens once, when the node I'm working with is first selected, and each time I select a subsequent node to work with it. I have tried capturing the OnClientKeyPressing event to prevent this, but the event is not even firing the first time I hit the spacebar. When I hit the spacebar after that, it seems to work fine, and the OnClientKeyPressing event fires. That is until I click on another node and try to type a space in the text box in that node--then the cycle repeats itself.

Is there a way to totally disable key selection for the entire tree?

EDIT
I've done some further investigation. When I edit a node, I am swapping out the innerHTML for an HTML block with text fields. When that happens, I unselect() the node because I don't want the background to change color, but that leaves no selected nodes in the tree. If I click any other node *before* I type a space into the textbox, everything works fine. So I'm guessing the tree needs to have at least one selected node if a keydown event occurs within it, otherwise it will automatically select the root node--is this correct?

Javascript If statement not working with onClientSelectedIndexCahnged event

Hello everyone,

I am trying to write a javscript function that opens a rad window if the user selects a certain value from a rad combo box.
The event fires fine when the user changes a value in the combo box. The problem is that the javascript IF statement seems to be ignored.

The radwindow opens even when the selected value is not 4...which I checked with document.write.

Im sure this is a school boy error - but I just cant see what the problem is...

    
            function OnClientSelectedIndexChanged(sender, args)  
        
            {  
        
               var item = args.get_item();  
        
               var selectedvalue = item.get_value();  
        
               //document.write("value is:" + selectedvalue);  
        
               if (selectedvalue="4")  
        
               {  
        
               window.radopen("csat.aspx","UserListDialog1");  
        
               return false;  
        
               }  
        
            }

[Solved] OverflowBehavior FireFox Height

I am having a problem setting the height of the scheduler control in FireFox (FF). IE displays correctly though.

As you can see in the screenshot the scroll button does not appear. I have read in other post that the scheduler height may need to be hard-coded...so I tried that and I couldn't get that to work.

If I perform an action on the scheduler; such as change the month; the scroll bars will appear correctly.

Notes:
The scheduler is in an asp:panel with the visible property set to false. When I check a checkbox I display the scheduler by setting the asp:panel to true

    
                                        <tr class="fieldRow" id="rowRecurringDetails3" style="height:260px"> 
        
                                            <td colspan="3" style="height:260px">

                                                    <div class="exampleColumnTextBox"> 
        
                                                        Example 
        
                                                    </div> 
        
                                                </div> 
        
                                            </td> 
        
                                        </tr>

Any ideas on how to get the scroll bar to appear in FireFox?

[Solved] Bind Radcombo in multirow edit mode in template column from code-behind with selected value

Hi,

I would like to bind Radcombo boxes in the grid from code-behind, because of the flexibility.

I want the combo to be related to another combo in the grid, but first i have problems with setting the selected value of the combo.

Here's a snippet of the grid columns:

                                                  <telerik:GridTemplateColumn UniqueName="CustomersTemplate" HeaderText="Kunde">         
                                                <ItemTemplate>         
                                                   <%#DataBinder.Eval(Container.DataItem, "CustID")%>         
                                                </ItemTemplate>         
                                                <EditItemTemplate>         
                                                    <telerik:RadComboBox AutoPostBack="true" Width="200px" ID="CustomersDropDown" runat="server"         
                                                            DataTextField="Company" DataValueField="CustID"          
                                                            AppendDataBoundItems="True" Skin="GiveNH3_default"         
                                                            ChangeTextOnKeyBoardNavigation="true" EnableLoadOnDemand="true" MarkFirstMatch="true" EnableEmbeddedSkins="false"         
                                                            >         
                                                            <Items>         
                                                                <telerik:RadComboBoxItem runat="server" Text=""          
                                                                    Value="0" />         
                                                            </Items>         
                                                    </telerik:RadComboBox>         
                                                </EditItemTemplate>         
                                            </telerik:GridTemplateColumn>         

And of the code-behind:

                    Protected Sub Grid_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs) Handles Grid.ItemDataBound         
              If (TypeOf e.Item Is GridEditableItem AndAlso CType(e.Item, GridEditableItem).IsInEditMode) Then         
            Using C As RadComboBox = CType(item.FindControl("CustomersDropDown"), RadComboBox)         
                            Dim dt As New DataTable         
                    Dim _CustTypeID = 1 'This could be different for each combo, and would be set from another combo in the grid         
                            Using cmd As New SqlCommand("SELECT * FROM Customers WHERE CustTypeID = " & _CustTypeID  & "", GetSQLConnection)         
                                Using dr = cmd.ExecuteReader         
                                    dt.Load(dr)         
                                End Using         
                            End Using         
                            C.DataSource = dt         
                            C.DataBind()         
                            Dim editItem = CType(e.Item, GridEditableItem)         
                     
                            'This doesn't return the corret value from saved value in the database - instead it returns the first value of the datasource         
                            Dim s = DataBinder.Eval(editItem.DataItem, "CustID").ToString         
                            C.SelectedValue = s         
                     
                        End Using         
            End if         
            End sub         

Can you point me in the right direction?

Any help appreciated!

( I use v. 2009.3.1314.35 of the web.ui)

FilterExpression cleared on sort

I am attempting to implement filtering for the first time using the RadGrid and have run into a problem/question/ignorance and I hope that someone can guide me in the correct direction. Here is the scenario:

I have a page that loads a grid with filtering by column disabled (set to false). The grid is using a LinqDataSource on the page and the DataSourceID is set. The grid works fine for sorting, paging, etc.

The user may click on a button that turns on the filtering for the grid. At this point the filtering is working great, including adding filters to multiple columns. However, once a user chooses a non-filtering action that causes a postback, such as a sort or changing the page size, the filter disappears from the data. The filter textboxes still show the values entered by the user, they are just not applied.

I have found that the FilterExpression on the MasterTableView object is an empty string, but the individual columns are retaining their CurrentFilterValue as the text entered into the filter textbox.

Do I need to manually "migrate" the filters from the columns up to the table level? If so, at what point in the page/control's life cycle would be appropriate?

Thanks for any help and guidance that you can offer.

client-side load not displaying items

Using your example for Performance with Web Services. My app returns 8000+ items from the service and loads in < 10 seconds. Yet the RCB appears empty after loading. What am I mssing?

    
                function RequestingLoadofCombo(sender, eventArgs)
