ToolTipManager: Changing TargetControl on the client

Hello,

I have a problem adding a TargetControl to my radToolTipManager on the client side. We are currently doing this in the code behind where it works like this.

tooltipManager.TargetControls.Add(ibAddToSelection.ClientID, value, true);

But now id like to do this on the clientside.

PS: This is not the same problem as the pinned "Changing TargetControl on the client". Since i also need to set the value.

column is not aligned while adding/removing columns

Hi,

We are using radGrid extensively in our project. We have enabled drag and drop and it also enable the user to add/remove columns. While we remove columns, columns are not alignned and it shows huge space where columns are removed. it got adjusted perfectly if you click " Ungroup " menu. It will be great if it gets adjusted at the moment column is removed. Please see the attached screen shot.

Thanks
Venkat

[Solved] unable to find postback data from RadGrid insert popup.

I am unable to locate how to access data from a GridEditMode.PopUp in your object model. In my RadGrid1_ItemCommand I have code to show the popup and this works(see below) but when I click on the insert button at the bottom of the popup the RadGrid1_ItemCommand fires again but I am unable to find the data I just entered into the popup. I have looked on source, on RadGrid1, on e.item. etc... Can you tell me where in your object model the popup data is stored? The only example like this I could find was using AllowAutomaticInserts="True" which is not an option for me. I need to validate the popup data in the codebehind before loading it into a collection and adding it to the grid.

Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand

Select Case e.CommandName

Case "Add"

' Add button pressed. Reset any rows in Edit mode

Dim grid As RadGrid = CType(source, RadGrid)

If (grid.EditItems.Count > 0) Then

grid.MasterTableView.ClearEditItems()

End If

' Manual "Add" Button pressed, put grid in Insert mode

If e.CommandName = "Add" Then

grid.MasterTableView.EditMode = GridEditMode.PopUp

e.Item.OwnerTableView.IsItemInserted = True

e.Item.OwnerTableView.Rebind()

End If

Case "PerformInsert"

'here is where I cannot find the popup data.

End Select

Sorting Files in ExplorerPopulated Event

The below code snippet is very close to resolving an issue with the sort order of .pdf and .xls documents, contained in a RadFileExplorer;

The following sort order is an example of the issue;
DD 1-19-12.pdf
DD 1-20-12.pdf
DD 1-3-12.pdf

The last file in the list (DD 1-3-12.pdf) should actually be listed first in this scenario; The date contained in the name of the file is probably causing the sort issue, but modifying the name of the file is not an option; In the below code snippet, I have replaced Name with Path - but to no avail;

The RadFileExplorer is being loaded in C#, by setting assigning ViewPaths and Upload Paths programmatically;

void RadFileExplorer1_ExplorerPopulated(object sender, RadFileExplorerPopulatedEventArgs e)

{

e.List.Sort(delegate(FileBrowserItem fileBrowserItem1, FileBrowserItem fileBrowserItem2)

{

return fileBrowserItem1.Name.CompareTo(fileBrowserItem2.Name);

});

}
