Hello,

Thanks for all the answers to my questions thus far!

This time I'm having trouble setting the alternativerowcolor of a gridview programmatically after setting the datasource. Essentially something like this would be ideal:

radGridView1.TableElement.AlternatingRowColor = Color.Blue;

However, I can see no way of getting to the table element from the gridview, even through the rootelement, mastergridviewtemplate and gridelement properties...

Thanks for the help!
Jeremy

Hi Jeremy,

You should cast the GridElement property to GridTableElement. You should additionally set the EnableAlternatingColor to true. Here is a sample:

((GridTableElement)this.radGridView1.GridElement).AlternatingRowColor = Color.Blue; 
this.radGridView1.EnableAlternatingRowColor = true

I hope this helps. If you have more questions, don't hesitate to ask.

All the best,

Hello Telerik Team,

I am looking to do the same functionality for the child templates, I want to change the alternating row colour for child template inside the Gridview, please guide me if there is any way to do so. basically I need alternating colour different in both main grid and child template, lets say Beige in main grid and Lavender in child template.

Many thanks,

Sheraz

Hi Sheraz Naseeb,

This can be done by handling the ChildViewExpanded event. Here is a sample:

this.radGridView1.ChildViewExpanded += new ChildViewExpandedEventHandler(radGridView1_ChildViewExpanded);
this.radGridView1.EnableAlternatingRowColor = true;
this.radGridView1.TableElement.AlternatingRowColor = Color.Beige;
 
void radGridView1_ChildViewExpanded(object sender, ChildViewExpandedEventArgs e)
{
    GridTableElement tableElement = (GridTableElement)this.radGridView1.GridViewElement.GetRowView(e.ChildRow.ViewInfo);
    tableElement.AlternatingRowColor = Color.Lavender;
}

Hi Edgar,

The ChildRow in this case is of type GridViewDetailsRowInfo and it lives inside the master GridTableElement. That is why when calling the GetRowView method, it returns the root table element. You can use the following code instead:
void rgvDetails_ChildViewExpanded(object sender, ChildViewExpandedEventArgs e)
{
    GridDetailViewRowElement row = radGridView1.TableElement.GetRowElement(e.ChildRow) as GridDetailViewRowElement;
    if (row != null)
    {
        row.ContentCell.ChildTableElement.AlternatingRowColor = Color.FromArgb(211, 211, 211);
    }
}

I hope it helps.
