I have a grid with a checkbox column. If a user marks the checkbox and then clicks on the "Save" button, I'm pulling the value of the checkbox, but it returns FALSE. It seems like the row is not being committed even when I have left the grid. What is trick for this?

(see screenshot)

Dim oPDFExporter As New GridViewPdfExport(oRadGridView)
With oPDFExporter
   AddHandler .CellFormatting, AddressOf oPDFExporter_CellFormatting
   AddHandler .CellPaint, AddressOf oPDFExporter_CellPaint
   .PageMargins = New Padding(10, 10, 10, 10)
   .ExportSettings = oPdfExportSettings
   If bLandScape Then
     .PageSize = New SizeF(297, 210)
   Else

Hi there,

I'm trying to recreate the "drag column to group by it" feature shown in the animation on this webpage:

http://www.telerik.com/support/kb/winforms/gridview/details/high-performance-with-radgridview-and-virtual-mode-including-filtering-sorting-and-grouping

Neither of the 2 C# projects at the bottom of the page have the drag grouping feature enabled by default.

Trying to drag a column header onto the grouping row causes a "invalid operation" cursor icon to be displayed

Please could you look into this and advise on how to get the demo source code giving the same results as the animation ?

Many thanks in advance,

James

I have recently updated to the latest version from 2016 Q1 and noticed a change in the way the RadTextBox displays when the Visual Studio 2012 Light theme is used.

The issue is easily reproduced by creating a new project and adding a RadTextBox with AutoSize as false and a Height of 20. Everything displays normally under the default theme.

Now add the Visual Studio 2012 Light theme and set the RTB to use it. The bottom of the RTB disappears. Not good. It isn't happy with anything under a Height of 24.

How can this issue be resolved? I've encountered similar issues with this theme in the past and I was not expecting the update to the latest version to break something which has been working just fine under older versions.

Hi,

When i use "radGridView1.Rows.Clear();" to clear rows from gridview, rows are removed in background but not visually until i click on expanding mark (+)

I want to know how to clear gridview rows in background and visually

I cannot seem to get the AnimatedPropertySetting to work with a radRadialGauge. We have this code to update the gauge from serial data approx every 5 seconds (via delegate):

public void DisplayTempChart(float temperature)  

 {             

//radialGaugeNeedle1.Value = temperature;   <----- when this is uncommented, the needle responds correctly         

AnimatedPropertySetting setting = new AnimatedPropertySetting(                 <----- this property setting never works, the needle is never updated

    RadRadialGaugeElement.ValueProperty,                 

     this.radRadialGauge1.Value,                  

     temperature,                 

     12,                 
     40);              

setting.ApplyEasingType = RadEasingType.OutBounce;              

setting.ApplyValue(radRadialGauge1.GaugeElement);         

}

Any help is appreciated!

Hi There,

I have created a marker called Car. This marker has a property called m_sLicensePlate.

How can i find that specific marker based on this property. The markers are in a specific layer.

My idea is something like :

Car findMarker(string p_sLicensePlate)

{

MapLayer carLayer = new MapLayer("Cars");

foreach (Car Item in carLayer.....)

{

    if (Item.m_sLicensePlate == p_sLicensePlate) return Item;

}

return null;

}

I was recently put in charge of updating a very old screen. It uses nested gridviews to drill down the mapping structure of a file. IE There is a list of files in the master template, detail template and file layout template among other child templates below these. 

    I need to insert a subdetail template for certain cases that then opens into the file layout template. Can I do this? In certain cases I want to display the detail then subdetail, and finally the file layout template while still being able to go from detail to layout for other entries (files). If it will work this way, I can have file layout and subdetail be tabs on the same level, I just need to have subdetail open the file layout below it. 

I have access to the latest Telerik version, though the program was written with an older version.
