I have a RADGrid with one button column and rest bound columns as follows;

<telerik:RadGrid ID="DocsList" runat="server" AllowPaging="True" GridLines="None"

OnNeedDataSource="DocsList_NeedDataSource">

<MasterTableView AutoGenerateColumns="False">

<Columns>

<telerik:GridBoundColumn FooterText="Document" UniqueName="Document" SortExpression="ContactTitle"

HeaderText="Document" DataField="Document" Resizable="true">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn FooterText="Index" UniqueName="Index" HeaderText="Index"

DataField="Index" Display="false">

<ItemStyle Width="0px" />

</telerik:GridBoundColumn>

<telerik:GridBoundColumn FooterText="MediaURL" UniqueName="MediaURL" HeaderText="MediaURL"

DataField="MediaURL" Display="false">

<ItemStyle Width="0px" />

</telerik:GridBoundColumn>

<telerik:GridButtonColumn FooterText="View" ButtonType="ImageButton" UniqueName="View"

HeaderText="View" ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center"

CommandName="Select" DataTextField="CustomerID" ImageUrl="~/Resources/Images/submit.png">

<ItemStyle Width="20px" />

</telerik:GridButtonColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

I have a few questions;

1. How can I attach an onclick event to the buttons in the button column so when a button in a row is clicked then value of one of the bound columns in the same row is returned?

2. The button images' seems to have an annoying shadow (image1.jpg attached). How can this be removed?

3. When this web page is being viewed in browser and browser window is scaled down the buttons start to crop instead of grid rescaling to allow the button to remain fully visible (image2.jpg attached). How can this be fixed?

Many Thanks

Regards

Hello John,

Straight to your questions:

In order to implement the desired functionality, you can handle the ItemCommand event of the grid and retrieve the corresponding value as it is explained in this help topic. Another approach is to manually add an OnClick event handlers of the buttons on ItemCreated.
The shadow cannot be caused by the RadGrid. Do you have a FormDecorator on the page? If the issue persists, please send us the image.
I recommend that you set the width of the grid to 100% and set the columns in pixels. In this way the columns will occupy the available space.

I hope this helps.

Best wishes,

Hi Mira

Many thanks.

For some reason I can’t get rid of the shadows under the buttons in the grid buttons column. Web page code below. Any help would be appreciated.

Thanks
