Hello, excuse me for my English I am French ...
I try to call in my code the RadUpload control with ID = radupload1

I tried several methods to find the RadUpload control example:

Dim RadUpload1 As RadUpload = CType(MyUserControl.FindControl("RadUpload1"), RadUpload)

but I get the error message:
Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Check the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Triggering an ajax refresh of a grid during an existing ajax refresh locks the grid

Long story short. I've got a link button that refreshes the content of a telerik grid.
I'm using the RadAjaxManager to handle the trigger and update controls.

The linkbutton is the trigger and the radgrid is one of the updated controls. I'm also using a loading panel to show that an update is in progress.

These grids can have a lot of data and may take a few seconds to refresh. So if somebody clicks refresh, and before it finishes updating, they click refresh again, the loading panel will display until a hard refresh of the page is done.

How can I avoid this behavior.

Thanks,
Javier

Edit: I've learned that this only happens when the LoadingPanel has a mindisplayTime.

How to deselect all selected rows in ALL grids?

Hello,

i have some a grid and every of its rows has a subgrid (NestedViewTemplate).
The option AllowMultiRowEdit is set to "false".
This option let me select only one row per grid (which is ok) but does not prevent to select a single row in each grid/subgrid!
Is there a way to select only 1 row in ALL grids/subgrids together?
I want to have only one selected row, no matter how many subgrids are open.
So if I select a row in a subgrid, the selected row in an other subgrid should be automatically deselected.

Any solution for my request?

By the way, it should be client side only!

Thanks,
Adam

onclick for GridClientSelectColumn select-all checkbox

I have a RadGrid with a GridClientSelectColumn. I need to enable and disable some buttons on the page, client-side, when certain rows are selected by clicking in the checkbox in each row's GridClientSelectColumn. I added an onclick event to the checkboxes for the required rows and that's all working fine.

My problem is with the select/deselect all checkboxes in the header and footer of the column. Clicking these changes the selection state of all of the rows, and it doesn't fire the onclick event for each of the individual row checkboxes. Which means I need to catch onclick on these, as well, and do some processing to decide whether the buttons should be enabled or disabled.

I didn't have any problem attaching a function to the onclick of the header checkbox:

protected void grd_ItemDataBound(object sender, GridItemEventArgs e)

if (e.Item is GridHeaderItem)

GridHeaderItem header = (GridHeaderItem)e.Item;

TableCell selectBoxCell = header["ClientSelectColumn"];

Control selectBoxControl = selectBoxCell.Controls[0];

CheckBox selectBox = selectBoxControl as CheckBox;

selectBox.Attributes["onclick"] = "return selectall_clicked(this);";

}

The function is called, when the checkbox is clicked, and returns true, but none of the row checkboxes are changed. It looks like the selection of all of the individual rows is done in an onclick handler, and I'm replacing it, instead of extending it.

There's probably a real simple way to add another onclick handler without eliminating an existing one. Any ideas?

RadAjaxLoadingPanel persists indefinitely

Hello,

I have a UserControl with several RadControls on it. The control is placed in an ASPX page which uses a MasterPage. My RadScriptManager is on the MasterPage. Within the control I have a RadGrid used to edit some user data. When the RadGrid initiates an Ajax postback, the RadAjaxLoadingPanel on the page fires. The postback completes, but the RadAjaxLoadingPanel never disappears. I have tried just about every trick I can find in the forums to no avail. The odd thing is that if I paste the contents of the UserControl into a standalone ASPX page, it works perfectly. The code for the UserControl follows. What am I doing wrong?

Download Attachment from GridAttachmentColumn

I followed the example online to download the attachment from a grid with a GridAttachmentColumn but I can't get the download working. The postback fires, ajax disables but the file is not sent. I am using Entity Framework.

<asp:Parameter Name="Id" Type="Int32" />

</SelectParameters>

</asp:EntityDataSource>

I disabled ajax fine (ConditionalPostback, etc.) and can upload no worries. But I can't get the attachment to download direct from the datasource. All the examples I can find are for SqlDataSource.

Heirarchical Grid disable "Add New Record" dynamically in Child gridviews

When a parent record is expanded I want to evaluate and either show or hide the AddNewRecordButton on the multiple detail tables . I found that I can turn it off in the ItemDataBound event with this code. Which appears to work until the grid rebinds and then it applies to all records universally. I think I am coming at this from the wrong direction. Is there a better way?

GridDataItem item = (GridDataItem)e.Item;

if (_currentDate < DateTime.Today && _currentDate != null)

{

((RadGrid)(item.Parent.Parent.Parent)).MasterTableView.DetailTables[0].CommandItemDisplay = Telerik.Web.UI.GridCommandItemDisplay.None;

((RadGrid)(item.Parent.Parent.Parent)).MasterTableView.DetailTables[1].CommandItemDisplay = Telerik.Web.UI.GridCommandItemDisplay.None;

((RadGrid)(item.Parent.Parent.Parent)).MasterTableView.DetailTables[2].CommandItemDisplay = Telerik.Web.UI.GridCommandItemDisplay.None;

}

i build an news manager with
datagrid / insert-update-delete with usercontrol ( in datagrid)
my news manager use 2 racontrols : editor (they work fine !!!) and radupload for litle image of the news all page are in masterpage :

In actu.aspx they have one raddatagrid they call webusercontrol.ascx

In webusercontrolascx they have radeditor and radupload.

this code work when they run in single page (not include in master page)

In masterpage the radeditor work well but the radupload return nothing I thinks i can’t find this control.

Protected Sub RadGrid1_UpdateCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.UpdateCommand

'Get the GridEditableItem of the RadGrid

Dim editedItem As GridEditableItem = TryCast(e.Item, GridEditableItem)

Dim MyUserControl As UserControl = CType(e.Item.FindControl(GridEditFormItem.EditFormUserControlID), UserControl)

'InitializeUpdateParameter(DirectCast(e.Item.FindControl("RadUpload1"), RadUpload))

'Get the primary key value using the DataKeyValue.

Dim actuID As String = editedItem.OwnerTableView.DataKeyValues(editedItem.ItemIndex)("ID").ToString()

'Access the textbox from the edit form template and store the values in string variables.

Dim Titre As String = CType(MyUserControl.FindControl("titre"), TextBox).Text

Dim Description As String = CType(MyUserControl.FindControl("RadEditor1"), RadEditor).Content

'Dim RadUpload1 As RadUpload = TryCast(e.Item.FindControl("RadUpload1"), RadUpload)

Dim RadUpload1 As RadUpload = CType(MyUserControl.FindControl("RadUpload1"), RadUpload)

Dim Imageup As String

If RadUpload1.UploadedFiles.Count > 0 Then

System.Threading.Thread.Sleep(3000)

End If

For Each f As UploadedFile In RadUpload1.UploadedFiles

If f.FileName <> "" Then

Imageup = f.GetName

Else

Imageup = "none"

'Dim imaup As String =

'Open the SqlConnection

End If

Try

SqlConnection.Open()

'Update Query to update the Datatable

Dim updateQuery As String = "UPDATE Actuvdotnet set TitreNews='" & Titre & "',Description='" & Description & "',Image='" & Imageup & "' where ID='" & actuID & "'"

SqlCommand.CommandText = updateQuery

SqlCommand.Connection = SqlConnection

SqlCommand.ExecuteNonQuery()

'Close the SqlConnection

SqlConnection.Close()

Catch ex As Exception

RadGrid1.Controls.Add(New LiteralControl("Impossible de mettre à jour la base de donnée : " + ex.Message))

Long text overflows into adjacent column

Hi,

I am new to your controls - but very impressed, keep it up.

My issue is that with a RadGrid (Q3 2008) when the text of a field is too long to fit in the column, and has no whitespace on which to break, the text simply overflows into the adjacent column. Have I missed a setting/option somewhere, in my case just forcing a break at the column width would be fine. Incidentally I get the same behaviour with the PDF export.

I have searched the support site and don't see anyone else asking, and I surely am not the only person getting the effect?
