Hi everyone,

I used the below code to show the Dropdown Popup everytime user hits Tab to go to that control. However, now the pop up will disappear if user clicks the little button on the right side of the DropDown control (normal way to show popup), this issue only happens on the first time when the control gets focused. Do you know how to fix this?

Thank you.

Private Sub DropDown_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles dpdBodyCondition.Enter
       Dim dpd As RadDropDownList = sender
       If dpd.IsPopupVisible = False Then
           dpd.Popup.Show(dpd)
       End If
   End Sub

I was able to create a bar chart with one set of bars (series)  and bound it to a DataTable without any problem.  Now my boss wants me to create two series - how do I bind it to a data source?  Do I bind it to a DataSet or bind the DataTables to each series?

1.  Is there a way that I can set the top level folder they can access. So lets say I have a directory structure  C:\Files\ExplorerFile\Ticket\4\Testing/  I set the explorer to open at C:\Files\ExplorerFile\Ticket\4\  They can navigate down and create new folders but I do not want them to go up past \4.

 

2. The default is set to Move but you can hold ctrl or shift to make it a copy.  Is there a way to set it to default to copy, or turn off the move function?

3. Is there a way to set the control o if you double click a file that it will open rather then right click and open?

I am trying to export a grid with different row heights.

I have AutoSizeRows = true.

On the apps screen the grid looks great. :)

But when I export it I get an error:

rowHeight should be greater or equal than 0 and less or equal than 600.

 spreadExporter.CellFormatting += spreadExporter_CellFormatting;

I have a spreadExporter_CellFormatting function and had:

if (e.GridCellInfo.RowInfo.Height > 600)
            {
                e.GridCellInfo.RowInfo.Height = 600;
            };

But it didnt stop the error happening.

Question, how do I check for the Row height value and set it before/during the export?

 

Thanks

Deasun.

I'm struggling to find anything in the documentation about how to style the bars in a bar chart.

I'd like the bars to look as per the attachment, with a shadow to the bottom and to the right.

With series defined as a BarSeries, I tried this, but it had no effect on the appearance of the bars:

series.BorderBoxStyle = Telerik.WinControls.BorderBoxStyle.FourBorders
series.BorderBottomShadowColor = Color.Gray
series.BorderRightShadowColor = Color.Gray
series.BorderRightWidth = 20
series.BorderBottomWidth = 40

Please could you let me know how to achieve this?

We have used RadGridView in our Windows Application and initially we use 2012 year versions of respective telerik dll's.

With those dll's on our specific form where we have used RadGridView, if user enter a filter value  to filter desired type of rows from all bunch of rows and close the and  reopen the form user can see his last entered filter value has been retained so the rows user can see are also filtered on the basis of filter value.

But when tried to Upgrade to 2020 version of respective telerik dll's we observed above mentioned functionality does not work.

Attached is the respective image of grid. Kindly assist on this.

Hi,
We have used a Telerik RadGridView in our Windows Application.
On specific form user has a option to right mouse click and open conditional formatting
then user gets a popup window of Conditional Formatting Rules Manager. 
In that Rules Manager window - we can see some properties under Format section such as CellBackColor and RowBackColor.
for these very particular options CellBackColor and RowBackColor we have set some standard color from code and want to keep it as a standard
thus want to prevent user to go and edit these properties and change the color to something else. 
So is it possible to completely disable to edit/hide these options (CellBackColor and RowBackColor) from code, so end user could not change it ?
Please find attached image of Rules Manager.

Hello,

I'm trying to run the RadGridView1_Scroll event in my application, but it is never triggered. I have tried in VB.NET and C#, and both Scroll events are not run.

Do I need to set any property first?

I verified the event handler and they are correctly defined.

In addition I've built another two projects in C# and VB.NET to test the Scroll event of the common GridView from Visual Studio. And the run ok.

Any help will be welcome. Thank you in advance.

Best regards,
Txarlie
