Hi,

I have a RadDropDownList control in my WinForms window. Right now, when I click on this control for the first time since opening a window, the whole text inside RadDropDownList text box is selected.  What I would like to happen is to just set cursor at the end of existing text with no text selection.

I tried handling most of the events for RadDropDownList (like GotFocus or Click) with:

When I checked during debugging, the selection is properly changed by my method, but in the end the text is selected whole by something else after that.

How can I get no text selection when clicking first time into this RadDropDownList text box?

Any ideas?

 

Thanks

Wojtek

 

hello, i have use the approach from article https://docs.telerik.com/devtools/winforms/knowledge-base/display-and-edit-html-text-in-grid-cells to

show html in gridview ,but after set the datasource , the html style didn't display.  Just like the following image ,i have set the color to red use font element:

the second problem is that ,when the grid view render finished ,the first cell of the gridview is selected and the backgroud color is blue, when i set the second cell to selected , the first cell bgcolor not changed. the method clearSelection of the GridView cann't work,even though i called this method in constructor ,the first cell bgcolor is still blue.

thanks

Hi,

Is it possible to have multiple grids in your chart when working with multiple axes? I only get the grid for the last axis, which is the yellow one in the image below. I would like to have a grid for each axis.

Hi,

I want to have functionality that user can add row in a grid but cannot update the existing data in a grid how we can do.
hope you understand my requirement.

i.e. Row Insert Allowed but update not allowed.

Thanks,
Shubham Jain

I'd like to hide the formula bar on the spreadsheet control. Can this be done?  (see attached)

Hello team,

As said in the title, I have a Chart with a cartesian grid visible and working fine. The problem is when I add a series programmatically and the series data is empty (see img.2): my chart displays the new axis as expected with no values since there is no data for the series, but the grid disappears.

Img.1 : Two series with data. The grid is visible fine.

Img.2: Two series with one empty. The grid disappears.

Why do some C# applications have an app.config file and others do not? Both of these solutions were initialized as Visual C# Windows Form Applications.

This one I created in Visual Studio Community version:

This screen capture bit is from a youtube tutorial. I followed along with the instructor in the video and He created it with a menu selection as a Visual C# -> Windows Form Application.

I tried following along with the tutorial and I noticed that the instructor's IDE, Visual Studio Community version, had a Solution Explorer that included the app.config file. I am curious and concerned because I believe system settings can be entered into the app.config file and so his code will be different from mine and my code might not even run at all.

 

I am using a gridview, I have a column created without linking to combo type data, in the createcell event I fill the combo list but when selecting an element it is not shown in the column, however its value is taken. Could someone help me now? break your head
