Hi,
How can I scroll the timeline programmatically.  When I click on an item in the list I want to make the  item in the timeline visible.
Thanks,
John

Hi, I have a RadGridView with a GridViewMaskBoxColumn that I want to use to allow the user to be able to enter any text up to 16 characters.

I have the following settings at the moment for the GridViewMaskBoxColumn:

MaskType = Standard
Mask = &&&&&&&&&&&&&&&& 

When I double click on a cell I see that underscores are used to indicate spaces. That's fine, and I'm able to edit the data. However, the underscores are persisting in my data when I move my cursor to a different field (i.e. when I'm done editing).  In other words:

Data before editing: "12345678        "
View of data while editing: "12345678________"  (underscores used to indicate spaces)
Data after editing: "12345678________"  (underscores have become part of the data).

Is there a way to prevent this? I don't want the underscores to be in my data after I'm done editing it.

Thanks for any help,

How can I filter Ganttview programmatically?  Thanks,  John

Hello Telerik

I have a little issue on adding row to a gridview using a objectquery(Of T) as datasource. The gridview is groupped on two level (fixed by design). Rows are added programmatically on a button click event with the following code.


The issue is that's the EnsureVisible do not expend the good group (on the yellow one on the picture).  If the "good" group is expended before the sub, all is goning fine (EnsureVisible do not expand the wrong group).

I have a radGridView (2014.2.715.40) component having among others 2 checkbox columns.  One is named "IsConcilie" and the other one is "IsRetenu".  For each row, when 1 of these columns is true, we can't set the other one to true.  Only one of these 2 columns may be true at a time.  If the user tries to put the second to true, he is advised.  The radGridView is named "MasterTemplate".

Because I want to be able to cancel the action, I added this event handler:
this.MasterTemplate.ValueChanging += new ValueChangingEventHandler(MasterTemplate_ValueChanging);

Then I coded the following:

void MasterTemplate_ValueChanging(object sender, ValueChangingEventArgs e)
{
    GridDataCellElement ce = this.MasterTemplate.CurrentCell;
    if (ce.Name == "IsConcilie")
    {
           if (e.NewValue.Equals(false)) return;
           if (this.MasterTemplate.CurrentRow.Cells["IsRetenu"].Equals(true))
           {
                MessageBox.Show( "You cannot verify a retained cheque", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Hand);
                e.Cancel = true;
            }
     }
     if (ce.Name == "IsRetenu")
     {
          if (e.NewValue.Equals(false)) return;
          if (this.MasterTemplate.CurrentRow.Cells["IsConcilie"].Equals(true))
          {
               MessageBox.Show("You cannot retain a verified cheque", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Hand);
               e.Cancel = true;
           }
      }
}

Unfortunately, whenever we click one of these checkboxes, the event is not fired.  What's wrong?

Thanks.

I have RadSplitButton with  2 options (2 radMenuItems)
Is it possible to add near to one of my items a RadSpinEditor in order to give the user the option to choose specific value number ?

I have a RadGrid in a form which contains 2 Combobox columns named "ITEMNAME" and "BATCHNO" respectively. I have loaded the first column with values from database. I need to populate the second combobox with values based on the value I choose from the first combobox. Which is the apt event to populate the values in a combo box based on another. If possible post a sample code. That would be useful to me.

I am creating a self-referencing Hierarchical Grid View. I checked the sample and it is setting image in CellFormatting event by accessing 

GridDataCellElement dataCell = e.CellElement as GridDataCellElement;
...........................................................
dataCell.ImageAlignment = ContentAlignment.MiddleLeft;
dataCell.Image = this.imageList1.Images[2]; 
dataCell.TextImageRelation = TextImageRelation.ImageBeforeText;


I want to attach image at the time of inserting the rows into the grid. How can I do that?

Another related question, how can I know if a row has child rows (nodes)

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.
