Hello,

I encountered the following issue (and found a solution) with GridView when using the Office2010Black theme:

When the font of the parent form (RadForm) was set to let's say Segoe UI; 9,75pt; style=Bold and this form contained a RadGridView, then the font of the GridView root element even got this font settings and thus all texts of the grid view were displayed in the font of the parent window with the following visual result:

Reason:

In the RootRadElement of the RadGridView the Font property wasn't set to a specific text repository.

Solution:

The font property of the RootRadElement of the RadGridView has to be set to a specific text repository.

Hi guys, how are You. 

I have one quesition and I hope You guys can help me.

Ok, datasource in my radgridview is DataTable( filled with DataAdapter / query). < - I have to use this because quety is using PIVOT  construct.

You can see the results of my query in attachment. Now You see that cells with the values? its 3 , 20, 8 , 10 etc. Now i want to change the color or what cell based on that value. Ex. if the cell value is 20 then 20 % of that cell should be Color.Red and so on, cell with Null value or 0 value should stay the same color ( default one ). 

I hope You guys will understand my question.

Hello,

I'm able to set the background color of the layout control by setting its BackColor property to a Color value but I can't find a way to reset the background color to the Theme's default. The Method ResetValue() is not available for RadLayoutControl.

Any help would be appreciated!

Thanks

Hi;

I am trying to selectAll all value from RadGridView. On ViewModel, I have a ListCollectionView, which represents all value from RadGridView. And i was able to take every value and set IsSelected to true.

foreach (var value in ListCollectionView)
{
value.IsSelected = true;
}

On RadGridView; those value that i can see, are highlighted but if i scroll down those i couldn't see are not  highlighted.

Is anyone why.

Thank you for help.

Hi, 

I am creating some custom RadDiagramShapes, using Shape -> Create new custom shape. I have also added custom connectors and configured the LightVisualElement child to display some text. (as in attachement)

Is there any way for these connectors to stay always visible in RadDiagram, even if shape is not selected?

I have tried to override the UpdateVisualStates method from RadDiagramShape, using VisualStateManager.GoToState(), with no success. 

I am using .NET Framework 4.5.2  and Telerik 2017.3.912.40

Thanks!

Hello. In my raddropdownlist is enabled autocomplete function (suggest mode). I'm intercept KeyUp event and when Text.Length in my TextBox element of RadDropDownList is 4,i make request to my API and fill dropDownList. (it's for optimization, because count of all my entities for dropDownList is more than 2 000 000 elements)

It's working fine, but only when I press the keys not very fast. If I quickly type a word to search, then a pop-up window with possible results for autocomplete does not showing! I can switch between options by pressing the keys down and up, and the options are changes in the TextBox element, but without a drop-down list.

Question: Is there any event that happens when autocompletion shows a drop-down list? I can catch a situation when the list does not drop out and manually execute the command to display.

Hello

We recently moved our winform application from standard forms to telerik forms. The application is a tray application, and before moving we used to us about 6MB of memory at startup. This stayed pretty stable. 

Since moving, I noticed we are now using 70MB of memory. Because this is a tray app, it could be oped hundreds of times on a single server from different users. 

I was trying to figure out what is using the memory, and created a blank winforms form app, and a blank winforms using telerik. I notice a huge immediate difference. The winforms app uses 2MB, the telerik app uses 20MB. 

Does anyone have any advise how I can reduced the amount of memory being used in a telerik winforms app?

Many thanks
