Hi,

I'm currently populating chat history when a forum opens. I want to have a button that clears the chat window and gets the latest conversation. I'm not finding a way to clear the message history however. If you happen to have some direction that would be great. 

Thanks for the assistance in advance.

Hi,

I tried an update to 2019.1.117 (from 2018.3.1016) with the Upgrade Wizard and after the "Upgrade Wizard Information" I'll get an "Telerik VSExtensions Error"

Here the StackTrace:

System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.
   bei Telerik.WinControls.VSX.Wizards.UpgradeProjectWizard.GetShouldEnableHDPI()

Does anyone got an idea what's missing?

Hi,

I have installed 2019.1.115.40 trial and I am testing RadGridView and trying to achieve require results using ColumnGroups view. From the documentation I have achieved the following.

ColumnGroupsViewDefinition view = new ColumnGroupsViewDefinition();

view.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[0].Rows[0].ColumnNames.Add("CompanyID");

I have learnt that the "CompanyID" should be same as of the Column-Heading of the data-table (data-source) provided to the grid.

My question is: Is it possible if I can change this "CompanyID" text after data has been loaded into the grid.

Or is there anything I can do, as with the datagridview, we use Name property for binding and Text property for display purpose.

Attached image might help.

Thanks

Hi,

Is it possible to change the design of the progressbar in the GraphicalViewItem? I would like to make it a bit bigger and change the color.

Hello,

I use multiselect in my gridview. I've found a strange behavior when I deselect a row among several selected rows.

For example,

Step 1, I've selected 4 rows by using Shift+left click. Here is the row stats.

Row Index | IsSelected | highlighted | isCurrent

    0            |     yes         |      yes       |      no

    1            |     yes         |      yes       |      no

    2            |     yes         |      yes       |      no

    3            |     yes         |      yes       |     yes

Step 2, I've deselected third row by using Ctrl+left click. In terms of display, nothing changes.
Row Index | IsSelected | highlighted | isCurrent
    0            |      yes       |        yes     |        no
    1            |     yes        |        yes     |        no
    2            |     no          |        yes     |       yes
    3            |     yes        |        yes      |       no

Step 3, I've deselected second row by using Ctrl+left click. In terms of display, 3 rows are highlighted, but actually 2 rows are selected.
Row Index | IsSelected | highlighted | isCurrent
    0            |     yes        |       yes       |       no
    1            |     no          |      yes        |      yes
    2            |     no          |       no        |      no
    3            |     yes         |      yes       |       no

I understand that current row and selected row are both highlighted. It's comprehensible to developer. But this behavior is not such friendly to software user.

I tried to disable highlight to current row by using row formatting. No luck.

To be more clear, I hope that only selected row can be highlighted.

Please help me. Thank you.

Hi Guys,

Im currently using winforms to run multiple displays through a RadDocking system and have been asked to refresh the displays at the highest frequency possible. And i have a couple of questions regarding this.

What "graphics engine" does the ui use if any, e.g. directX etc.

Are there any optimizations i might have missed for updating the controls at high frequencies for controls like chartViews, GridViews and any other common control general optimizations.

Cheers

Dan
