How to automatically insert a column value

I have a grid and I am using an insert command to enter records to an underneath table.

How can I automatically insert a column value (for example user_id) to a column?

I have made this column read only so that the user enters some values but he doesn't see that user_id column.

I get the user_id using the following code :

    
            string UserID; //globally declare the UserId   
        
                protected void RadGrid1_PreRender(object sender, EventArgs e)  
        
                {  
        
                    MembershipUser myObject = Membership.GetUser();  
        
                    UserID = myObject.ProviderUserKey.ToString();  
        
                }

OnColumnMoving event

I have few questions regarding usage of the client side OnColumnMooving..() events.
1.
I would like to cancel column moving event if certain condition occurred (using ReorderColumnsOnClient="true")
for example here is my js method that cancels the event for first 2 columns in the grid.
function ColumnMoving(sender, eventArgs)
{
    if(eventArgs.get_gridColumn().get_element().cellIndex < 2)
    {
        eventArgs.set_cancel(true);
    }
}
But what i find is when an event is canceled once, it never fires again for any of the other column.

2. Is it possible to use this event when ReorderColumnsOnClient is set to "false"?

3. How can I find out the destination index of the column that is being reordered(meaning where is it about to be moved)?

Thank you
Polina

MS Office Thumbnails with Telerik??

Hi, I'm wondering if there is a way to generate Thumbnails from a PowerPoint or Excel file? I have many MS Office documents, which I link to inside my SharePoint site, but it would be much nicer if I was able to use a graphical thumbnail image of the particular documents. Thanks in advance for any help!

[Solved] An item with the same key has already been added in SitePanelbar.ascx.cs

Hi, we're getting the following error message intermittently - at least several times a day - in the file \Sitefinity\UserControls\Navigation\SitePanelbar.ascx.cs . We have made a few customizations to the ItemDataBound method in the file, but we can't quite place what might be happening. Can anyone help us figure out this issue?

Menu Disappear problem

Hi

I am using menu as a context menu on grid.

I am inserting a new menu item at runtime from JavaScript. My problem is that the Menu does not disappear after on click event of the newly created item. The click event puts a drop down list through javascript in one of the columns of selected row.

var childItem = new Telerik.Web.UI.RadMenuItem();

childItem.set_text(strOption);

childItem._click = AdjustOwner_LoadDropdown; // AdjustOwner_LoadDropdown is a function

menu.get_items().insert(2, childItem);

Am I missing setting some property?

how to rebind radgrid within a panelbar from button

hi. I have an issue that I can't seem to work around. I have a panelbar (pb1) on main.ascx. within pb1 i have two user controls each holding a radgrid ctlr1, and ctrl2 , respectively rg1 and rg2. I need a method to rebind rg1 and rg2 at the same time. For some reason I can't reference controls within the panelbar? What I was hoping to do was put a button on main.ascx, and using ajax manager control the two grids that way. This does work if I put a rg1.mastertableview.rebind() in the rg1_prerender event. the problem though is obvious that every time i call an action on the grid, it rebinds, so that mean I can't collapse any grouped items.
I'm pretty rookie at this type of thing so apologies if this should be very basic. my code is below for a basic setup
PS: I want to use a button to initiate the call as I am clicking it from a radwindow javascript.
note: sample is
main.ascx

Rebinf two grids in JavaScript

Hi

I have two simple grids on web page.
When I try to call function like :

function Rebind()
{
    tableView = $find("Grid1").get_masterTableView();
    tableView.rebind();
}

Grid1 going to rebind and show new dataSet.

But if I call :

function Rebind()
{
    tableView = $find("Grid1").get_masterTableView();
    tableView.rebind();
    tableViewW = $find("Grid2").get_masterTableView();
    tableViewW.rebind();
}

... Grid1 and Grid2 do not show new dataSet. Shows information about update on it's status bar only. Why ??

Regards
Krzysztof
