Dear

I'm applying security by disable all controls with certain CssClass based on permission, for example I'm adding Insert CssClass to controls I want to disable or enable base on user role.
Now this is working great with RadGrid but unfortunately when using Detail/Hierarchy Grid within RadGrid I can't apply this logic, I don't know why, can you help me please?

Hello,

Please try with below code snippet.

foreach (GridDataItem item in RadGrid1.MasterTableView.Items)

{

if (item.HasChildItems)

{

foreach (GridDataItem citem in item.ChildItem.NestedTableViews[0].Items)

{

ImageButton ibtn = citem["Edit"].Controls[0] as

ImageButton; // Edit is column UniqueName

ibtn.Visible = false;

}

<Columns>

<telerik:GridButtonColumn ButtonType="ImageButton" CommandName="Edit" FilterControlAltText="Filter column column"

ButtonCssClass="Update" UniqueName="Edit" HeaderStyle-Width="3%">

<HeaderStyle Width="3%" />

</telerik:GridButtonColumn>

</Columns>

Hello,

1.

Please try to execute this code snippet in the page_Prerender event because Grid binding data (generate button) after the page_load event.

var securedControls = Helpers.Methods.GetAllControls(this)

.OfType<WebControl>()

.Where(c => c.CssClass == "Insert" ||

c.CssClass == "Update"||

c.CssClass == "Delete");

2. Please try with above solution if it is not worked then have to access controls using my last reply code snippet.

Because this is the functionality/limitation from .net framework.

There is not any issue of DetailTableView. - We can not access the controls directly which was inside the Data control (like : repeater, GridView...etc).

Let me know if any concern.

Thanks,
Jayesh Goyani
