I have a situation where I have a bunch of Rad Controls (RadTextbox, RadSpinEditor, RadDropDownList) on a User Control. That User Control is then injected into a custom Windows MMC SnapIn. When I do this the TabIndex of the controls is for some reason reversed and the Tab key does not stop on the RadDropDownList anymore. When I use the same User Control inside of a Form or RadForm the TabIndex is as expected and the Tab key stop on the RadDropDownList. I have verified that the TabIndex values are sequential and in the right order and that the TabStop property is True for all the controls.

After some extra digging I found that inside of MMC SnapIn the TabIndex seems to follow the order in which the RadControls are added to the User Control in the Designer code behind file. The TabIndex property is completely ignored.

I am using UI for WinForms 2015 Q3 with C# and Visual Studio 2015.

Is there some bug when RadControls don't have a parent form and are injected into some other parent container?

I can't find any COMPLETE CRUD example on the web, forum and demo page. Anyone has a clue where I could find one?

I need to support these features:
-Support for One to Many relations.
-Support for Many to Many relations.
-Deleting relation (mapping table row) when deleting a Many to Many row from child grid.
-Change FK to null when deleting a One to Many row from a child grid
-Saving data On Changes.

Entity Framework or DataSet / DataAdapters will do. EF would be preferable (as it already handles all my relation requirements) but I believe it is not officially supported yet (and I had some troubles getting child deletion to work).

Thanks!

Hi All

Hopefully I have missed something simple but I cannot seem to get SelectedValue to work in a databound list control.

The scenario is that I have a ListControl which has been filled from a DataTable with the DisplayMember set to a Name and the ValueMember set to a Database Id.

I programatically try to set the SelectedValue to a given Database Id, nothing happens, the selected value does not change, the ListControl selection point does not move, no events generated.

The various SearchString functions are useless to me because they work on the DisplayMember not the ValueMember and I would have duplicate names in my list.

I have tried writing my own routine to find the value manually and return an index, but I am also having problems with SelectedIndex not being set properly. This seems to work fine in simple scenarios but in a more complex scenario where the list is being changed and updated, it seems to stop working. As yet I cannot determine what is causing the problem with SelectedIndex but if I can get SelectedValue to work I do not have to worry about it.

I am using the Q1 2011 controls

Any feedback gratefully received.

Peter

Hi,

I am using CheckedDropDownList control in my UI. I have nearly 154 items to be handled with this control. So the UI becomes hanging after selecting and clearing it programmatically. I am using the following codes.

For selection

foreach (var text in dbValues)
    {
        foreach (RadCheckedListDataItem item in this.radCheckedDropDownList1.Items)
        {
            if (item.Text == text)
            {
                item.Checked = true;
            }
        }
    }

For Clearing

radCheckedDropDownList1. CheckedItems.Clear();

if there any convenient way to do this??. Please advice.

I noticed that the RadTextBox does not have a Character Casing option of Proper Casing, which is basically capitalizing the first letter of each word. It would be nice if the RadTextBox control had this property.

I have a ListView with the ViewTyp-property set to IconsView.

The icons contains both an image and text.

My problem is that only about 15 characters is shown in the icon. Overflowing text isn't shown.

Is there a way to automatically expand the icon size so that all the containing text is shown?

Hi have a problem showing data with a two level hierachy... I have followed the documentation and tutorials on this subject, creating child templates and setting relations etc...

I am displaying Candidates assigned to a single booking.

The top level displays the Candidate Name (and includes the CandiateId)
        The next level displays skills (which includes the skill Id, but NOT the CandidateId - This data is actually associated to the single booking, so repeated under every candidate)
                The third level displays the pay per skill AND per candidate (So needs to link to SkillId on the level above and link to the Candidate ID 2 levels above)

 

I have added the GridViewRelation for the third level to the second, but when I add the relation from the third level to the first, it seems to be simply ignored.

Can anyone help?

Hi,

I am usingRadListControl to show some bound data and implemented drag-drop following the instruction given here. The Drag drop works okay, but I need to implement scrolling while dragging an item so that it can be dropped anywhere the user wants to. I've tried to search for it, but was not successful. Could anyone please provide any solution or workaround for this?

Thanks
