Error in httpErrorPageScripts.js with 2012.08.28 hotfix

I installed the August 28 hotfix for 2012Q2 to see if a reported display problem with the Menu control using a 2-column submenu had been fixed. When I installed that update, I now see an error instead of a display problem when a submenu is set to 2-column display.

The error occurs in httpErrorPageScripts.js, in function initConnectionStatus(), on the line:
checkConnection.innerText = L_CONNECTION_ON_TEXT;
The constant L_CONNECTION_ON_TEXT is undefined. The same error occurs for other L_ constants.

Nested RadGrid and selecting only one row in the whole grid

Hi,

I tried searching the forum and found a couple of threads, but they didn't help. I have a RadGrid that has another RadGrid nested which also has another nested RadGrid. So there are 3 levels: Level 1 has information about a costumer, level 2 has information about customer´s purchases, and level 3 has info about products that the costumer has bought during the purchase.

I have a GridClientSelectColumn (and the AllowRowSelect="True" in <ClientSettings>) on the level 2 (the purchases). I can access the selected purchase by iterating trough all items in the whole radgrid and checking which item has its Selected set to true.

My problem is I cannot figure out how to make it so that only one purhase (level 2 item) could be selected in the whole grid. Right now I can select one purchase per each customer, which is not at all what I want. I guess I should somehow always unselect the previous selection just before selecting the new one.

I tried to subscribe to SelectedIndexChanged of the nested radgrid, but it doesn´t seem to fire. Which event should I use?

I also found out that this could done with some client side javascript trick, but I am not sure how to do it. Also I would like to do this on the server side if possible...

So what is the "official" way to achieve this "select only one row among nested radgrids" -scenario?

GridButtonColumn image is not displayed

I am not seeing the button image in a previously working application when I use Telerik version 2012.3.1030.45 (targeting Asp.Net 4.5) or 2012.3.1030.40 (targeting Asp.Net 4.0). I tried both a GridButtonColumn and a GridClientDeleteColumn, and neither one displays the image. Looking at the source code shows the image source attribute is an empty string. The identical code works fine in version 2012.2.724.40.

<telerik:GridClientDeleteColumn UniqueName="TestDeleteColumn"

HeaderText="Delete" HeaderStyle-Width="45" Text="Delete Invitation"

ButtonType="ImageButton" ImageUrl="../Images/Delete.gif"

ConfirmTitle="Delete?" ConfirmDialogType="RadWindow"

ConfirmTextFields="PersonDisplay" ConfirmTextFormatString="Delete invited speaker {0}?"

/>

<telerik:GridButtonColumn UniqueName="DeleteColumn" ButtonType="ImageButton"

CommandName="Delete" Text="Delete Speaker" ImageUrl="~/Images/Delete.gif"

HeaderText="Delete" HeaderStyle-Width="45"

ConfirmTitle="Delete?" ConfirmDialogType="RadWindow"

ConfirmTextFields="PersonDisplay" ConfirmTextFormatString="Delete invited speaker {0}?"

>

<ItemStyle HorizontalAlign="Center" CssClass="CursorHand" />

</telerik:GridButtonColumn>

radUpload issues in radGrid using Ajax

I am having issues when I use radUpload in the radGrid, I can't insert new records when I use radUpload.

I am using radTabs and Multipage and .ascx files. My radGrid is on user control file.
My code is below

<telerik:RadCodeBlock runat="server" ID="RadCodeBlock1">

<script type="text/javascript">

var uploadId;

var AuthorImagesListId;

//on insert and update buttons click temporarily disables ajax to perform upload actions

function conditionalPostback(sender, e) {

var theRegexp = new RegExp("\.UpdateButton$|\.PerformInsertButton$", "ig");

if (e.EventTarget.match(theRegexp)) {

var upload = $find(uploadId);

//AJAX is disabled only if file is selected for upload

if (upload.getFileInputs()[0].value != "") {

e.set_enableAjax(false);

Add GridTemplateColumn to Radgrid programmatically

Hi,
I have the following environment: VS 2010, Asp.Net, Visual Basic and Telerik controls.

I started this project by trying to implement this solution with an unbound Radgrid, but then the Radgrid html code was not sent to the client in the page source file, I decided to use the bound Radgrid method.
Here is what i'm trying now:
I created an .aspx page that has an empty (no columns defined) Radgrid control bound to a datasource that I'm populating in the Onclick event code of a button using the following code:

Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click

SqlDataSource1.SelectCommand = "exec CreateForecastEntry 'F2012v1', 'USA-ILMO-T1' "
grdForecast.DataBind()

End Sub

The datasource query returns a dataset with a variable number of columns (months) depending on some user settings. I want the user to be able to edit the grid columns, so I want to add GridTemplateColumns with Textboxes for each of the columns.

The grid should look similar to this:

the Query returns in this case 3 columns, which I want to transform into 5 columns like this:

Column names: Item | January | February | T_January | T_February
Column types: GridBoundColumn | GridBoundColumn | GridBoundColumn | GridTemplateColumn (textbox) | GridTemplateColumn (textbox)

Note: The number of months will be variable.

I have tried using the following code to create the columns, but it does not create the appropriate number of columns, and it creates them at the beginning of the grid:

Protected Sub grdForecast_ItemCreated(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles grdForecast.ItemCreated
Dim tc As New GridTemplateColumn

        tc.HeaderText = "qty_" & e.Item.UniqueID
        tc.UniqueName = "qty1_" & e.Item.UniqueID
        tc.ItemTemplate = New MyTemplate(tc.UniqueName)
        grdForecast.MasterTableView.Columns.Add(tc)

    End Sub
    Private Class MyTemplate
        Implements ITemplate
        Protected textBox As TextBox
        Private colname As String

        Public Sub New(ByVal cName As String)
            MyBase.New()
            colname = cName
        End Sub

        Public Sub InstantiateIn(ByVal container As System.Web.UI.Control) Implements ITemplate.InstantiateIn
            textBox = New TextBox
            textBox.ID = "abc"
            container.Controls.Add(textBox)
        End Sub
    End Class

This code will create a random number of GridTemplateColumns and I'm able to see them in the browser page source code, but I cannot access the textboxes content using this code:

    Protected Sub Button2_Click(sender As Object, e As System.EventArgs) Handles Button2.Click
        Dim quantity As TextBox
        For Each row As GridDataItem In grdForecast.Items
             quantity = CType(row.FindControl("abc"), TextBox)
            quantity = Nothing
        Next
    End Sub

Any insight on what I'm doing wrong would be appreciated. Thanks
Eduardo

<asp:TableCell><telerik:RadTextBox ID="TrainingCompanyTextBox" runat="server" /></asp:TableCell>

</asp:TableRow>

OnClientItemExpand, I want to set focus to the TrainingCompanyTextBox control with javascript. I've tried different ways of setting focus to the contorl, but i can't find the solution.

How can I do this?
