RoundRectShape auto disappear from ShapedForm

Hi,

I tried to add the "RoundRectShape1" to each of my form by change their shape to "RoundRectShape". But, the problem I am facing now is...sometimes, the RoundRectShape1 will just auto disappear (for random page, like entire project having 10 pages, 5 RoundRectShape might be disappear). When I go back to the shape and change it back to "RoundRectShape", if I am lucky, it will add "RoundRectShape1" again. If I am not, then it will add "RoundRectShape2", "RoundRectShape3" and so on.......

Please advice.

[Solved] RadTextbox - Keyboard navigation missing Shift+Tab functionality

I am using RadTextbox in one of my project to get consistent UI throughout application and I am really happy to achieve that using Telerik controls.

But one thing I found in while testing my app that RadTextbox don't support Shift+Tab functionality. This is used to navigate backward using keyboard.

Is there any property need to be enabled to achieve this?

Also while using keyboard - when button get focus, it don't change it look.
I believe it should look same as Mouse over state.

My application has kind of data entry form and require keyboard navigation for fast input. I will really applicate if both textbox and button can behave as good as they work with mouse.

radCarousel Start/Stop Animation

Folks,

In my app I needed to display a large variety of chart selections for the user to choose. In doing so, I didn't want the user to have to click or hold the Next or Previous buttons to execute the repeater functionality. What I really wanted was to have a method to start and stop the animation, and once started, will continue exactly as if the user continually clicked on the Next or Previous button, stopping once a carousel item was selected. Don't have it perfected yet where it's as smooth flowing as I like, but I think this would be great functionality for you to add.

Kind Regards,
Matt

application using ribbonbar moved to another machine doesn't run

Hello,

I have got this issue and don't know how to solve it.

On my development machine (win xp home sp2) I can build a solution using radRibbonBar (free control as a benefit of registration of MSVS2008 Express) and run it with no problem.
Than I move the executable to other machine (win xp prof sp2) and it crashes on start. It is not a development machine so there is no VS installed.

The crash memory dump says only System.IO.FileNotFound.
Rest is a stack dump etc, so it doesn't say to much.

I have tried to run it on other development machine but with no radRibbonBar installed and it crashed on startup as well.

Is it some common issue?

I will provide more detailed info if needed.

Event Fired for Unselecting Node

I'm looking for a way to determine when the SelectedNodes property changes.

When an item is added to SelectedNodes, this is easy because the Selected and Selecting events are fired. I know there's no corresponding event for unselecting a node. However, is there any other event that is fired when the selection status of a node changes?

Thanks for your help.

ImageColumn NoFilter Doesn't work

Hello,
I Use winform Q3 2007.
I want to disable filtering feature of an ImageColumns. So i set ;

gridViewImageColumn1.Filter.Function = GridKnownFunction.NoFilter;

But, firstly it doesnt prevent user inputing filter text box of the column,
secondly and most important one, when you input something in the filter textbox of the image coloumn and select some menu item in the filtering context menu ( i mean "equal", "greater", ...menu ) it still wants to filter the expression and so program fails with
System.Data.SyntaxErrorException: The expression contains invalid name
message.

for now, I overcome this case by coding this,

private

void BLSecimDataGrid_MasterGridViewTemplate_FilterChanging(object sender, FilterChangingEventArgs e)
{
if (sender is Telerik.WinControls.UI.GridViewImageColumn)
{
GridViewImageColumn gridViewImageColumn = ((Telerik.WinControls.UI.GridViewImageColumn)sender;
if (!string.IsNullOrEmpty(e.NewStringValue)) e.Cancel = true;
}
}

i think it's a bug and i want to know, if there is another solution without coding and just setting some property :)

Thank you

Serkan APUL.

[Solved] Change cell using CellFormatting

Question regarding CellFormatting

I have just bought a couple of licenses of radcontrols. And I must say; I am very impressed! It helps me save loads of time.

I have a radgrid filled with data (like this):

Name Bit (should be hidden) Phone

John        1                                    22445566
Mike       0                                    44556677
Joan        1                                    44556677

And I want to change the background-color on Name-cell if Bit is set to 1. The background color for the cell with John and Joan should be yellow. And Mike should stay as it is.

This is normally functionality that I would solve using the OnItemDataBound-event. But now I guess I have to use the CellFormatting-event instead.

I figured out that I could not grab the value of Bit, because the column is hidden (radgridDialog.Columns["myBitField"].IsVisible = false;)

So then I tried to prefix my name-column from my stored procedure. So John and Joan became <pre>John and <pre>Joan. Not the nicest solution I have seen. But I was starting to get desperate. Do anyone have an better idea?

The logic almost work. The only thing I'm having problems with now is to change the value of the cell. My function looks like this:

    
            void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)  
        
            {  
        
                    // exclude header element in the data column                         
        
                    if (e.CellElement.ColumnInfo is GridViewDataColumn && !(e.CellElement.RowElement is GridHeaderRowElement))  
        
                    {  
        
                         GridViewDataColumn column = (GridViewDataColumn)e.CellElement.ColumnInfo;  
        
                          if (column.DataField == "Name")  
        
                          {  
        
                              if (e.CellElement.Value.ToString().StartsWith("<pre>"))  
        
                              {  
        
                                     Font font = e.CellElement.Font;  
        
                //What should the line below be? I see that e.CellElement.Value is readonly  
        
                                     //e.CellElement.SetValue(Telerik.WinControls.RadProperty rd, (object)e.CellElement.Value.ToString().Replace("<pre>", ""));  
        
                                     e.CellElement.Font = font;  
        
                                     e.CellElement.BackColor = Color.Yellow;  
        
                                     e.CellElement.ForeColor = Color.Tomato;  
        
                              }  
        
                         }  
        
                  }  
        
            }

Thanks

DragDrop between trees

I've got two trees in my form. One has a list of items and one has a list of categories those items can go into. The items don't have to be in a category and they can be in more than one category.

I'd like the user to be able to drag a node from the list tree and capture that it is dropped on a category and have it show up as a child node under that category. By default this works but the node is actually removed from the list tree and put in the other tree. I'd like it to not get removed from the list but have it act more like a copy operation than a move.

I'm sure I can make this work by capturing the right events and adding in some logic, but before going through the trouble of tracking down exactly what I needed to do, I wanted to make sure I wasn't missing some kind of flag or setting on the tree that would do exactly what I'm talking about automatically.
