Hello Nandkishor Phalke,

I suggest you to place this HyperlinkButton inside a GridViewDataColumn's Header property directly:

<telerikGrid:RadGridView x:Name="radGridView1" Width="450" Height="450"......>

<telerikGrid:RadGridView.Columns>

<telerikGrid:GridViewDataColumn ......>

<telerikGrid:GridViewDataColumn.Header>
<Grid>

<HyperlinkButton x:Name="lnkCompanyNameInStyle" Content="Select Company to Compare".../>
</Grid>

</telerikGrid:GridViewDataColumn.Header>

</telerikGrid:GridViewDataColumn>

</telerikGrid:RadGridView.Columns>

</telerikGrid:RadGridView>

Hi Nandkishor Phalke,

Since Header property is object you can add anything. For example:

column.Header = new HyperlinkButton();

What if you have a bunch of column headers with checkboxes in them. And then wihin a function you wanted to loop through all of the header cells and find out the lable of those which are checked..What's way to fo this ?

Hello Sajjad Shah,

Could you please take a look at this forum thread:CheckboxInGridView.
Generally you could add the checkbox as it is shown in the previous post and using our extension method ChildrenOfType to extract the checkBoxes and determine whether it is checked or not,you can find more info about this here.
Please let me know if I can assist you further.

Thanks. This part I had worked out already and got it to work. I have another question. I am trying to automatcally check the checkboxes on the column header. I am using Style for checkboxes on the column header. I have a web service (WCF) which brings the data and the columns get defined. I have to check few boxes by default (when user looks at the the screen). Although my logic to check tick the checboxes comes after the service call return. My number of columns are still not expected as what i want them to be. Is there any specifc event i should be after which gets fired after the column count on the grid is : what i expect it to be.

Thanks.

Hello,

You can cast desired column Header property to CheckBox and set desired properties.
