Rad Button Inside a Rad Grid
Hi Srikanth,
When the page index changes the grid items are re-crated and re-jump to the new data. This ways that the ItemCreted and ItemDataBound events volition fire for each detail. Since these are the same items in the grid, just their information changes, their indexes remain the same. And then, such behavior would exist expected.
Perhaps you can consider getting some flag from the jump row instead of its alphabetize: https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/rows/accessing-cells-and-rows#accessing-raw-field-information-and-central-values.
For instance, dataItem.GetDataKeyValue("someField") will give you lot an object that is that field'due south contents. Just make sure to add that field to the DataKeyValues collection of the MasterTableView.
Once y'all extract that flag from the row, you tin can replace e.Item.ItemIndex with information technology in the logic that disables/enables buttons and then it only fires for the rows you want, not for all rows.

Marin Bratanov

TimePicker doesn't work at all
Hi Adrian,
When creating a custom editor it is necessary to set the proper name attribute for it to the relevant field. This way the value will be bound to the underlying editor correctly. Delight modify the editor function like in the following snippet and permit me know how the behavior changes:
editor: function (container, options) {
var input = $( "<input/>" );
input.attr( "proper name" , options.field);
input.appendTo(container);
input.kendoTimePicker();
}
In case the behavior persists delight send united states a dojo sample where the result is replicated so we can examine information technology locally.

Change and filter TrackBall tooltip information
Hi Telerik Team,
I'thou currently looking into the Telerik WPF chart command (RadCartesianChart with line serial).
What I'm trying to effigy out is a mode to modify the tooltip information of a TrackBall.
Currently the ToolTip info says Value: x, Category: y like in your screenshot on this
page: https://docs.telerik.com/devtools/wpf/controls/radchartview/features/behaviors/trackball
I desire to create a different design for it, reading, Date: twenty.xx.xxxx, NumberOf: y and
filter all 0 values (y) out of the tooltip info. I'm using MVVM pattern with C#. I got to
the point where I can change the tooltip text (binding to TrackInfoUpdated consequence) but at
this bespeak I can't get the values of the current TrackBall data series. In the VS2017 debugger
the values and categories are visible but it seems that these values are not publicly bachelor.
Peradventure you lot've an idea how to get the values?
Cheers in advance.
Best Regards,
Thomas

Go column values from radgrid outside of grid events of client side
Howdy,
From the code yous have shared I tin encounter that Buttons are created and added programmatically to the grid within the ItemDataBound issue. The problem is that the event fires only one time when the grid is bounden, every other time a postback is washed the buttons volition not be bachelor on the page. When creating or changing RadGrid's structure programmatically, information technology is important to use the correct right outcome and method do it. Meet Creating a RadGrid Programmatically assistance article describing this topic.
Run into as well:
- Creating Template Columns Programmatically
- Include Additional Action Button
After for accessing rows, cells, prison cell values, controls of built-in columns or well for template columns, I tin can recommend the the Accessing Cells and Rows article. This describes the approach for both client and server side programming. Here is some other article that can exist useful in your in such scenarios: Using the GetItems GetColumn and GetColumnSafe Methods.
I hope this answers your concerns.

IsHidden binding not showing Pane
I'm setting the style of my RadPane just similar the 'VisualStudio' example:
< Style TargetType = "telerik:RadPane" BasedOn = "{StaticResource RadPaneStyle}" >
< Setter Holding = "CanDockInDocum entHost" Value = "False" />
< Setter Belongings = "Header" Value = "{Binding Header}" />
< Setter Holding = "IsHidden" Value = "{Binding IsHidden, Mode=TwoWay}" />
</ Fashion >
< Style TargetType = "telerik:RadDocumentPane" BasedOn = "{StaticResource RadPaneStyle}" >
< Setter Property = "Header" Value = "{Binding Header}" />
< Setter Property = "IsHidden" Value = "{Binding IsHidden, Mode=TwoWay}" />
</ Style >
My ViewModel has the IsHidden belongings, and is notifying fine. Removing the panels works. Notwithstanding, 'unhiding' them fails.
protected override RadPane CreatePaneForItem( object item)
{
var viewModel = item every bit IDockPane;
if (viewModel == cipher ) return base .CreatePaneForItem(item);
var pane = viewModel.PaneType == PaneType.DocumentPane ? new RadDocumentPane() : new RadPane();
pane.DataContext = item;
RadDocking.SetSerializationTag(pane, viewModel.Header);
pane.Content = new TextBlock { Text = "Exam" };
return pane;
}
Later some searching these forums, it seems an result with the binding not updating because it'due south removed from the visual tree? If then, is there any alternatives? How is the Visual Studio case getting effectually this? I can find no other lawmaking that attempts to restore the hidden panes - but perchance I'm missing it.
I tried simply listening for the IsHidden holding alter:
viewModel.PropertyChanged += (sender, args) =>
{
pane.IsHidden = viewModel.IsHidden;
};
And this half works. The first time it does cypher, but the second fourth dimension y'all 'cycle' the IsHidden property (say with a checkbox) information technology appears again! Except the tabs are missing their headers.
The DataContext is fix fine, and if I become in and press 'reset' on the binding in the Visual Studio live belongings editor it refreshes just fine to the correct header.

Overflow Button
Hi
I take implemented a command bar within a docked side panel as tin exist seen in the commencement image.
I have hidden the overflow and grips and fix the stretch horizontal belongings to true on the strip chemical element AND the textbox then the text box automatically resizes if the width of the console is changed. So far and so skillful.
The trouble I am having is that when I resize the panel the refresh button disapears much earlier than expected - see second paradigm. Its almost as if there is a hidden push button to the right of the refresh push. i only desire the refresh push to disapear when the right border is about to touch the icon - see image 3.
Does everyone know how I tin do this?
