Help with getting rid of Child thick border

I am trying to develop a programatically defined hierarchical grid as the example pictured here: photohere

I want to get rid of the annoying thick orange border around the child grid, and also find a way so that the horizontal size of the child grid to be the same as the parent grid, and not extending to the right. I do not want to create a new style, but rather try to do it programmatically.

I have found a similar reference in the forum that supposedly takes care of the first problem, listed here:http://www.telerik.com/community/forums/winforms/gridview/hierarchy-child-size.aspx , but does not seem to do the trick, since the cell formating event never ends this loop.

Any help would be greatly appreciated.

Regards,

George

Infinite Loop when Validating

I have a strange problem. In the below code when conditions exist that causes one of the messages to be displayed, after the message is acknowledged (stepping this through) the validate is immediately called again. If I remove the messages, then this behavior is not exhibited. Am I doing something wrong, or is this a bug. I'm running the latest of the lastest.

private void grdSleeves_Validating(object sender, CancelEventArgs e)

{

try

{

if (sender is RadGridView)

{

RadGridView grid = (RadGridView)sender;

if (grid.CurrentCell.ColumnIndex == (int)enum_grid_sleeve.picked)

{

int picked = Convert.ToInt32(grid.ActiveEditor.Value);

int available = Convert.ToInt32(grid.CurrentRow.Cells[(int)enum_grid_sleeve.paqavailable].Value);

int required = Convert.ToInt32(grid.CurrentRow.Cells[(int)enum_grid_sleeve.paq].Value);

if (available < picked) { e.Cancel = true; MessageBox.Show("Picking more than available."); }

else if (required < picked) {e.Cancel = true; MessageBox.Show("Picking more than required."); }

}

catch { }

}

Changing RadTreeNode backcolor at runtime

Hi,

We are having issues with changing RadTreeNode backcolor at runtime. Setting the backcolor works fine, but resetting it back to transparent color messes up node highlight and selection highligh. We use Vista theme, so the selected node would normally have blue highlight with gradient, but after setting background color and resetting it back, the selected item highlight looses gradient and becomes just white with blue border. Is there a better way to permanently hightlight a node? We just swithed from standard .Net TreeView and used Status icon for that, which works differently in RadTreeView.

                    // Resetting color         
            node.BackColor = Color.FromArgb(0, 0, 0, 0);         
            node.BackColor2 = Color.FromArgb(0, 0, 0, 0);         
                     
            // Setting custom background         
            node.BackColor = Color.FromArgb(0xEA, 0xF3, 0xFB);         
            node.BackColor2 = Color.FromArgb(0x1E, 0x77, 0xD3);         

We use RadControls for WinForms 2009.1.414.

Thanks,

Gregory

DropdownElement rendering problem

I have tested a styled radComboBox using some theme, but I notice something. When I click on open dropdown button first time, combo shows a dropdown list under it but not shows shadow around it, some times dropdown list is bigger than radcombobox width size; at second time when dropdown list is displayed, shadows is shown and dropdown list is width sized like radcombobox width size, but another thing that is the main problem is when radComboBox is big size of width to show great deal of text, scrollbars disapear!!

What could be done?

How to enable border in the disagner without creating a new theme?

Hi,

Is there a way to use RadTreeView control with the same theme in different places with and without the border? Looks like drawing a border around the control is controlled by the theme and creating an extra theme doesn't seem to be reasonable just for this purpose. I found a work around by setting the RadTreeView.TreeViewElement.DrawBorder property to true. But it would be more logical and convinient to make at available in the Designer. Should i submit it as a feature request?

Thanks

Checkbox filter within Gridview

Question #1
When adding a checkbox column to a gridview and when I turn on the filter option of the grid there is a checkbox that shows up as part of the filter. How can I turn that into a select all checkbox instead of filtering on it? Is there a better alternative to doing this?

Question #2
How come when I add a checkbox to my gridview before filling the gridview with data it just shows the checkbox and it doesn't look right/good is there a way to just have a clear grid or at least make it look better?

Thank You

RadTextBoxElement.Multiline

Hello -

I have a very sophisticated RadElement hierarchy that contains RadTextBoxElements at the leaves. So far, I've only needed single line text boxes, but I now need to begin supporting multi-line text boxes. I see that RadTextBox has a Multiline property, but I don't see such a property on RadTextBoxElement even though I do see the MultilineChanged event. I'm hoping there is some way (even if through a backdoor) to make a RadTextBoxElement do multi-line text editing.

Thanks,

- Mike

Creating columns add runtime

Hello,

i have a problem with the winform radgrid.

Trying to add columns runtime with the following loop:

public void CreateGridProductieMonitor(List<string> Kolommen)

{

radGridViewProductie.DataSource = schrapViewBindingSource;

foreach (string Kol in Kolommen)

{

if (!string.IsNullOrEmpty(Kol.Trim()))

{

GridViewTextBoxColumn textBoxColumn = new GridViewTextBoxColumn();

textBoxColumn.UniqueName = Kol;

textBoxColumn.HeaderText = Kol;

textBoxColumn.FieldName = Kol;

radGridViewProductie.MasterGridViewTemplate.Columns.Add(textBoxColumn);

}

The datasource of the grid is a generic list. The fieldname is 100% correct.
Only the first column shows data. The other columns are empty. When i change the order of the columns the result is the same. The first column added shows data.
I tried adding the columns before and after binding to the datasource.

Greetings Tim

Adding items to Quick Access toolbar overlow menu

I am using C# and Telerik controls version 2009.1.9.414.

In the Quick Access toolbar overflow menu, I would like to create additional items. I am referring to items like "Show Below the Ribbon" and "Minimize the Ribbon", not the items at the top that are added dynamically to correspond to the toolbar buttons.

Is there a way to add items? I try:

    
            this.radRibbonBar1.RibbonBarElement.QuickAccessToolBar.OverflowButtonElement.DropDownMenu.Items.Add(new RadMenuItem("testing"));

in the OverflowButtonElement_DropDownOpening event handler, but the CPU goes to 100% and the app seems to hang.

Any suggestions?

Thanks,
Nick
