Put a RadChart in a DetailTable

[charles]

Hi, for my application i have to create a RadGrid. In this RadGrid there's a list of item and when i click on one of them it opens and we can find inside a GridTableView which have inside of it some text in the first column and in the second column a RadChart. As far as I get, I can display everything but i had to save the RadChart as an image and then put it inside the Grid. But now I have some new things that I have to do and that doesn't work anymore. This way i cant use any mapping from my CodeBehind since it's a simple image. To achieve this i've followed this example http://demos.telerik.com/aspnet-ajax/grid/examples/programming/detailtabledatabind/defaultcs.aspx. I'm creating my RadChart inside the DetailTableDataBind event and add it to the grid. But if i want to keep the mapping I have to insert the RadChart and not the image of it. If I do that it displays only that: Telerik.Web.UI.RadChart.

Can you help me find the problem please.

I also have the same problem.
I need tu put a RadChart in a RadGrid but in a DetailTables.
When I want to bind de RadChart with some data I do:

 protected void dataBoundRadGrid1(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = e.Item as GridDataItem;
            chart = item["GraphicColumn"].FindControl("RadChart1") as RadChart;


            if (chart != null) chart.DataBind();
        }
    }

but chart is always null.

Hello Vincent,

Try the following code to access RadChart in DetailTableView.
aspx:

<telerik:GridTableView Name="Detail" . .></telerik:GridTableView>

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
 if (e.Item is GridDataItem && e.Item.OwnerTableView.Name == "Detail")
 {
    GridDataItem item = (GridDataItem)e.Item;
    RadChart chart = item.FindControl("RadChart1") as RadChart;
 }
}

Thanks,
Princy.

This is my ASPNET code. I've put the c# code you gave me but e.Item.OwnerTableView.Name is always "" (null).

Hi Vincent,

I am not quiet sure about your requirement. I guess you want to access the RadChart in the ItemDataBound event. I don't understand the way you are binding the GridTableView. If you are binding it in code behind and the HierarchyLoadMode is ServerOnDemand (default) then DataBind of a child GridTableView would only take place when an item is Expanded.If you want to access the RadChart before the item is expanded, please set the HierarchyLoadMode to Client/ServerBind. Please take a look into this documentation for more information.

Please provide the way you are binding the GridTableView, if this does'nt help.

Thanks,
Princy.
