I'm following along with the "Grid - Hierarchy with Templates" example. There's a parent table, when the parent table row is expanded a template with several tabs is displayed, each tab contains a sub grid of the parent.  For the most part my version of this example works great.

The example seems to use "a little magic" to communicate the data key for the parent rows to the controls in the NestedViewTemplate. An ASP Label's text is bound to the data key for the rows (it is set not visible). A reference to the magic Label is then used in the ObjectDataSource to fetch sub grid data as needed.

My issues relates to having to do some validation of data before new data is Inserted. To do the validation I need to know the parent table row's data key in the code behind from the magic Label. I know how to get the Label's for all rows such as in the code example below. My issue is figuring out which Label to take the key from as there's a Label for each row in the Parent table.

    protected void BudgetAdjustmentItemRadGrid_InsertCommand(object sender, GridCommandEventArgs e)
    {

        Label dataKeyLabel = null;
        int id = 0;
        foreach (GridNestedViewItem item1 in ParentRadGrid.MasterTableView.GetItems(GridItemType.NestedView))
        {
            dataKeyLabel = (Label)item1.FindControl("DataKeyLabel");
            if (dataKeyLabel != null)
            {
                id = Convert.ToInt32(dataKeyLabel.Text);
            }
        }

    }

Maybe there's a better way to get the parent table row's data key. Let me know if you know one. I did find something that looked promising in the documentation. There's reference to a Parent Data Key and Detail Data Key such as below. However I can't find a working example of these settings. Furthermore my app won't compile when I attempt to use them.

       <NestedViewSettings DataSourceID="SqlDataSource2"><telerik:ParentTableRelation MasterKeyField="CustomerID" DetailKeyField="CustomeriD"/></NestedViewSettings>

I have a radgrid which holds a table to be modified by the user.

The columns are ID (hidden as its the identity in the table), Name, Phone number, Address etc.

When I click the btnAdd button, i get the popup and it shows ID, Name and Phone number, Address etc.

All good, but I want to hide the ID, so the user cannot insert a value.  

For the grid itself I use 

    Private Sub dgGrid_ColumnCreated(sender As Object, e As GridColumnCreatedEventArgs) Handles dgGrid.ColumnCreated
        If e.Column.UniqueName <> "Actions" AndAlso e.Column.UniqueName <> "EditColumn" Then
            If e.Column.UniqueName = "ID" Then
                e.Column.Display = False
                Exit Sub
            End If

hello

i have the following problem. i have a radgrid which is totally created at runtime and i need to add two ways of editing

i mean,  i added a GridEditCommandColumn and then, because only one GridEditCommandColumn can be added to radgrid, i created a GridButtonColumn

here is the code:

the problem rises when in the radGrid_ItemCommand event i need to execute two different operations due to which button has been clicked

here is the pseudocode:

how can i solve ?

thanks in advance

Hello!
I have horisontal scrolling bar, in aspx file it looks like:

<telerik:RadMenu ID="ActionListMenu" SkinID="Menu" OnItemDataBound="OnActionButtonDataBound" 
                        Width="100%" Flow="Horizontal" runat="server" DefaultGroupSettings-Flow="Horizontal" DefaultGroupSettings-RepeatColumns="1" CssClass="ActionsBar">
                    </telerik:RadMenu>

and in website it's:

<div class="rmScrollWrap rmRootGroup rmHorizontal" style="overflow-x: hidden; overflow-y: hidden; width: 100%; overflow: visible;">
    <ul class="rmRootScrollGroup" style="position: relative; width: 519px; display: block; left: -35px;">
         <li class="rmItem " ... />
         ...
         <li class="rmItem " ... />
    </ul>
    <a class="rmLeftArrow" style="z-index: 2000; top: 0px; left: -1px;" href="#" jQuery191013909904974899967="13">
    <a class="rmRightArrow" style="z-index: 2000; top: 0px; right: -1px;" href="#" jQuery191013909904974899967="11">
</div>

Now I'm trying to make it scroll farther (more than one "rmItem").
To do so I tried to add events to "rmLeftArrow" and "rmRightArrow" that would change "rmRootScrollGroup" "left" css property, but after all it comming back to the place it shuld be without my stript.
I think that after clicking on arrow Telerik's script sets expected value of "rmRootScrollGroup" "left" css property to some variable, and after moving it by any way (mouse scrolling, clicking/mouseovering arrows) it will start from the point it shuld be.

Example:
After clicking on the right arrow, position of rmRootScrollGroup shuld change from 0px to -25px.
I add another -200px (by attatching click event on arrow, something like .style.left = (.style.left - 200) + 'px' ))
so now rmRootScrollGroup has property left: -225px. And it really appears on -225px.
The problem is, that after mouseovering on arrow it will return to -25px :(

Is there any way to make it moving further?

I try to use FrozenColumn for Grid after Read Demo. But when I apply FrozenColumn & UseStaticHeader, Column will always display only with match width of grid (Other column will lost) and When Scroll, only data will scroll while header still the same (that doesn't match with data column). Freeze column doesn't work too.

I have attached picture of My Grid (I using Simple Databinding) , "Initial" is when data loaded and "Scrolled" is when I scrolled Horizontal.

Below is my code 

I've been trying to get the Filter Template on the grid to work with a RadComboBox, but have not been successful. I'm binding to a dataset which is a little different than the example at Filter Template Example. The dropdown seems to load correctly the first time, but then when I make a selection it fails. I'm guessing it's in the client code because it never gets back to the .

I'm getting the error:

Selection out of range
Parameter name: value

Below is my code:

Note, in the example you have the rebind that I've commented out above. When I do this, my ComboBox comes out empty. If I leave it out, then I get the values in the Combo Box. 

I'm having a secondary problem with the ComboBox itself. Sometimes, the text in the  is huge, other times it's the right size. I have no idea what's causing this.

Thanks
Rodney

RadCombox version is 2017 R2 (2017.05.03).

When user chooses second item: "empty", the SelectedIndex=1 when AllowCustomText=False,
but SelectedIndex=-1 if the value is empty when AllowCustomText=True.

I think it's a bug for empty value in AllowCustomText mode.
