[Solved] Rad Grid Get Control Type of Control Inside Grid Template Column

Hi,

I am dumping the contents of the rad grid into a data table and am trying to find a control that is inside the item template of a grid template column without knowing what he control name is.

I am looping through all the columns in the grid and based on the data type, performing some custom formatting before inserting the row into the data table.

My question is, if the column is a grid template column, how can I find the control that is inside the <Item Template> without actually knowing the name.

Below is the code I am using to loop through the grid.

Dim dr As DataRow

For Each dataItem As GridDataItem In Me.rgvMainGrid.MasterTableView.Items

dr = exportTable.NewRow

For Each column As GridColumn In Me.rgvMainGrid.MasterTableView.Columns

If column.Display = True Then

Select Case column.ColumnType

Case "GridBoundColumn", "GridDropDownColumn", "GridDateTimeColumn", "GridNumericColumn", "GridCalculatedColumn"

strFields = strFields + IIf(strFields = Nothing, "", ",") + column.UniqueName.ToString + "," + column.HeaderText.ToString

Select Case column.DataType.ToString

Case "System.String"

If dataItem(column.UniqueName).Text.ToString = " " Then

dr(column.UniqueName) = ""

Else

dr(column.UniqueName) = "'" + dataItem(column.UniqueName).Text.ToString

End If

Case "System.Decimal", "System.Double", "System.Single"

If dataItem(column.UniqueName).Text.ToString = " " Then

dr(column.UniqueName) = 0

Else

dr(column.UniqueName) = FormatNumber(dataItem(column.UniqueName).Text.ToString, 2, TriState.False, TriState.False, TriState.False)

End If

Case "System.Int16", "System.Int32", "System.Int64", "System.Single"

If dataItem(column.UniqueName).Text.ToString = " " Then

dr(column.UniqueName) = 0

Else

dr(column.UniqueName) = FormatNumber(dataItem(column.UniqueName).Text.ToString, 0, TriState.False, TriState.False, TriState.False)

End If

Case "System.DateTime"

If dataItem(column.UniqueName).Text.ToString = " " Then

dr(column.UniqueName) = ""

Else

dr(column.UniqueName) = dataItem(column.UniqueName).Text.ToString

End If

End Select

Case "GridTemplateColumn"

Case Else

'Do Nothing

End Select

End If

Next

exportTable.Rows.Add(dr)

Next

Thanks for your assistance.

Using telerik controls in VS2010 project template

I am obviously very new to the .net world. Please forgive me if the solution is obvious btu goggling hasn't turned up any info I can apply directly to my situation. I am using Visual Studio 2010. I am creating a "start" project that includes all the things I need for any app on my site, including css, certain images, and external javascript files.

When I export this project to a template, it does not include the Telerik assembly file for some reason, so When I start a new project from the exported template, It doesn't have the assembly file and I have to manually re-add the Telerik refernce.

What am I doing wrong? How can I fix this?

Thank You.

hiding the asyncupload container and persisting upload

I have a wizard-like screen that has several steps. The first step includes an async-upload. I have set the PostbackTriggers property so that only the submit button on the last step causes the file to be uploaded. This all works fine to persist the file upload through the postbacks associated with the Next/Previous buttons of the wizard, however, the way the wizard works is to hide/show panel controls depending on which step is currently being viewed. If I set the panel.visible property to false for the panel which contains the async-upload, I notice when I return to this step by setting panel.visible to true, the upload is gone. I have found one potential workaround by setting panel.Style("display") = "block" or "none" depending on whether I want to hide it or not and this seems to persist the upload. I would prefer to use the built-in asp.net visible property. I am wondering if this is a known limitation or am I doing something wrong?

Usercontrol on dynamically created dock return Null Reference Exception

Hello,

I'm creating a 'dashboard' on which the user can dynamically add dock controls. Each dock control contains a certain usercontrol.

Using the examples from the Telerik site, I already have created the dashboard and the functionality to add dock controls. But when I add a usercontrol, I get a null reference exception form the usercontrol. The usercontrol itself contains several buttons, which are null when I call dockLayout.Controls.Add(dock);
I'm not sure, but I think it has to do with the state of the page lifecycle.

The dock-widget example (http://www.telerik.com/help/aspnet-ajax/dock-widgets.html) I've using is probably the way to solve this problem, but the example doesn't explain how LoadControl() should be implemented. Is this the missing link? If so, can you give an example code, based on the provided example?

<asp:Content ID="Content3" ContentPlaceHolderID="MainContent" runat="server">
    <telerik:RadAjaxLoadingPanel runat="server" ID="ralpConfiguration">
    </telerik:RadAjaxLoadingPanel>
 
    <telerik:RadAjaxPanel runat="server" ID="rapConfiguration" LoadingPanelID="ralpConfiguration">
          <telerik:RadWindow ID="modalPopup" runat="server" Width="360px" Height="360px" Modal="true">
               <ContentTemplate>
                    <asp:DropDownList runat="server" ID="ddlControls" ></asp:DropDownList>
                    <asp:Button runat="server" ID="btnAddRadDock" Text="Add" />
               </ContentTemplate>
          </telerik:RadWindow>
