Your 'Insert Code' function ...

... is it possible to replicate your Insert Code option in the forums within the radEditor?

I'm writing a Knowledge Base system and the ability to insert and maintain formatted code would be really valuable!

Programmatically Created GridTemplateColumn Values Disappear After Paging

Hello,

I have thoroughly looked through the online help for how to create GridTemplateColumns programmatically and have been successful in doing so. My whole goal is to have a GridTemplateColumn whose ItemTemplate just shows a value (Employee Name), and whose EditTemplate has a RadComboBox with a MultiColumnDropdown. I assumed I had to use a template column for this because I didn't see any way to do this with a GridDropDownColumn.

My grid is tied to an ObjectDataSource that is tied to a DataTable stored as a session variable.

Initially, the data loads fine and everything looks good. Unfortunately, when I advance to another grid page after the inital load of the web form, the values in the GridTemplateColumn disappear while the other non-template bound columns correctly display data for the next page.

I notice that when I hookup the DataBinding event on the InstantiateIn method, it is called for each row in the page on the initial load of the form. This is NOT called again after moving to another grid page. Maybe the trick here is to get that event to fire on a page change, or maybe it's something else? Anyway, here is the code how I'm generating the column. I have tried to move the loading of the grid into the Page_Init function instead of the Page_Load, but to no avail. Your help is greatly appreciated!

This method "remakes" an already created bound column into a GridTemplateColumn. I do this so I can call it generically all over our application. NOTE that I only have the ItemTemplate at the moment.

                    Public Sub SetMutliColumnDropDown(ByVal ColumnName As String, ByVal dt As DataTable, ByVal HeaderText As String, ByVal ValueField As String, ByVal TextField As String, ByVal HiddenColumns As String)         
                    Session("dd" & ColumnName) = dt         
                    Dim ColIndex As Integer = RadGrid1.MasterTableView.Columns.IndexOf(RadGrid1.MasterTableView.Columns.FindByUniqueName(ColumnName))         
                    RadGrid1.MasterTableView.Columns.Remove(RadGrid1.MasterTableView.Columns.FindByUniqueName(ColumnName))         
                     
                    Dim col As New GridTemplateColumn()         
                    RadGrid1.MasterTableView.Columns.AddAt(ColIndex, col)         
                    col.ItemTemplate = New MultiColumnDropDownItemTemplate(dt, ValueField, TextField, HiddenColumns)

Client-Side OnColumnCreated

we have a multi language project, so i need to set the columns headertext dynamicaly.

So what is the problem.
I cannot use server-side oncolumncreated because i am using client-side databinding with paging. I wrote a script like this for the client-side event.
My question is: How can i assign the text for rowheader ?
I used this column.get_parent().headerRow but i know this isnt the right one, and i couldnt found the correct one. If someone can give an answer for this i will be happy.

Regards...

    
            function ColumnCreated(sender, eventArgs) 
        
                { 
        
                    var column = eventArgs.get_column(); 
        
                    if (column.get_dataField() == "RET_CODE") 
        
                         column.get_parent().headerRow = '<%= Messages.GetMessage(1112) %>'; 
        
                    if (column.get_dataField() == "RET_DELIVERYNAME") 
        
                        column.get_parent().headerRow = '<%= Messages.GetMessage(1442) %>'; 
        
                    if (column.get_dataField() == "RET_DELIVERY_ADDRESS") 
        
                        column.get_parent().headerRow = '<%= Messages.GetMessage(1398) %>'; 
        
                    if (column.get_dataField() == "RET_CONTACTNAME") 
        
                        column.get_parent().headerRow = '<%= Messages.GetMessage(1029) %>'; 
        
                    if (column.get_dataField() == "RET_PHONE") 
        
                        column.get_parent().headerRow = '<%= Messages.GetMessage(1031) %>'; 
        
                    if (column.get_dataField() == "CL_STATUS") 
        
                        column.set_visible(false);

Client-side findItemByText

I have a simple "State" dropdown where the text values of items are the abbreviations of States (e.g. "VA"). I allow the user to type in a custom value because I didn't want to put a "Select State" kind of option but want to use filtering. Anyway, user types in "va" and the client-side "findItemByText" does not find the item for "VA". Is there any way to get this method to NOT be case sensitive?

Is there any way to get RadUpload to work in a tooltip?

Been trying to find a way all weekend to get the RadUpload control to work in a tooltip. I understand the Ajax limitation, and have been trying to figure out a way to disable the ajax call that the tooltip makes but can not figure out how. Does anyone know if it can be done?

Basically I have a tooltip that shows with LoadOnDemand that contains a RadUpload control.

Thanks..

Row Click Expaning to DetailTable Issue

I have a table that I want to expand the row and display the Detail Table when the row is clicked by the user. I achieve that like so:

    
            If e.CommandName = "RowClick" Then 
        
                        Dim item As GridDataItem = e.Item 
        
                        If item.Expanded = True Then 
        
                            item.Expanded = False 
        
                        Else 
        
                            item.Expanded = True 
        
                        End If 
        
                    End If

However I get an error on the "item.expanded = true"

Procedure or function 'sp_Select_Affiliate_Purchased_Breakdown' expects parameter '@source_id', which was not supplied.

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

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

        SelectCommand="sp_Select_Affiliate_Purchased_Breakdown"

        SelectCommandType="StoredProcedure">

        <SelectParameters>

            <asp:Parameter Name="source_id" Type="Int32" DefaultValue="@source_id" />

        </SelectParameters>

    </asp:SqlDataSource>

Why would this be happening? The Parameter is right in the data source...
