I need to create a gridview (winforms) that has two comboboxes where one of the comboboxes' available values are determined by the selection in the first combobox. This seems straightforward but I have run into problems with all the approaches I have tried so far.

I tried the following:
1) In the Cell Value Changed event I tried rebinding the  dependent combobox in the based on the selection in the first. The problem that I encounter is that while the combobox is is rebound with the data I am looking for it rebinds the combobox in all of the rows in the grid blanking out selections whose value is no longer one of the combobox values.

2) I also tried capturing the cell formatting event and adding a new RadComboBoxElement to the cell and populating the the combobox element by adding items to it.  While this does work, the grid's theme doesn't flow through and the grid appears be acting buggy. I've run into a problem when populating this combobox element when it is scrolled off the screen (row isnt visible because the user has to scroll to see it). When part of a row is scrolled off the screen the combobox is painted half in the grid and half on top of the horizantal scroll bar which doesn't look professional. This approach also yields a combobox that has a different look and feel than the other comboboxs in the grid because it doesnt have a distinct edit mode, its always in edit mode, always shows the drop down arrow image.

Is there any way to do this? I need to populate the values of one combobox based on the selection of another combobox in a RadGridView. At this point I'm becoming very frustrated with these components.

In Q3 2014 control, i can not find the "CanUserFreezeColumns" method in the "RadGridView". I want to show the effect like the demo. 
http://demos.telerik.com/silverlight/#GridView/Scroll

'Telerik.WinControls.UI.RadGridView' does not contain a definition for 'CanUserFreezeColumns' and no extension method 'CanUserFreezeColumns' accepting a first argument of type 'Telerik.WinControls.UI.RadGridView' could be found (are you missing a using directive or an assembly reference?) 

Hi,

Can you please let me know if the BandedGridView functionality has been implemented in the RadGridView under UI for WinForms.

Attaching an image for your understanding.

I'm playing around with the Ribbon bar and have multiple tabs which displays user controls for different sections of the program i'm playing around with. One section is products that is basically a datagrid with add, edit and delete functionality, this is all on a single user control. Normally I'd put the add, edit and update buttons in this user control so the main view doesn't get cluttered with code.

What is the best or most proper way to access the ribbon buttons from a user control?

  

I have GridView with ContextMenu, i added to this ContextMenu several options after the user click right click on item from my GridView  and i want to know how can i change the color of the item that the mouse is in, you can see he default color in the attach screenshot

I set the datasource of multicolumncombobox everytime dropdown opening event is fired.
But on the first instance, it only show the header and a vertical scroll like 1st.png attachment. It did have rows since if I press downbutton, a row will be selected
while on the second instance and later, it works like 2nd.png attachment.


Any suggestions?

Hi,
I have a radGridView control with two columns, the second one should contain string values in every cell except for the last one which should be a checkbox. I'm not able to put the checkbox inside the cell. I've tried using the "CreateCell" event of the gridview in this way:


The problem is that e.Row.RowInfo.Index is not the "absolute" row index but it's relative to the displayed cells. So, if I have a resized form the result of e.Row.RowInfo.Index could be any number between 0 and rows.Count.
Can anyone help me? Thanks.

Hello everyone

I'm trying to sort a RadGridView by clicking a header cell. The name of the column which should be sorted is "priority" and it's type is double. I have some other column which has different values. All these columns together build a "priority number" like 1.0, 2.0, 2.1 etc. And this "priority number" is in column called "priority". And now I'm trying to sort the priority column. It shouldn't matter which column header i click, it just have to sort the priority column. I tried this code:

private void radGridView1_CellClick(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
{
    if (e.RowIndex == -1)
    {
        if (e.Column.Name == "va")
        {
            if (radGridView1.Columns["priority"].SortOrder == RadSortOrder.Ascending)
            {
                radGridView1.Columns["priority"].Sort(RadSortOrder.Descending, false);
            }

            else if (radGridView1.Columns["priority"].SortOrder == RadSortOrder.Descending)
            {
                radGridView1.Columns["priority"].Sort(RadSortOrder.Ascending, false);
            }

            else
            {
                radGridView1.Columns["priority"].Sort(RadSortOrder.Ascending, false);
            }
        }
    }
}

But it doesn't work. When I hit "va" column header, it sorts the "va" column and not the "priority" column. But in debugging mode I can see it goes through this code. Can anyone please tell me why it's not sorting "priority" column?

Thank you
