Hello,


I am working with a hierarchical GridView and I'd like to recover the information displayed on the child part I just clicked on (where there is a "+" sign).

So how can I access the informations displayed on this child part when entering the following function :

 

 

private

 

 

void OnGridViewMyChildViewExpanding(object sender, ChildViewExpandingEventArgs childViewExpandingEventArgs)  ?

I tried several tricks with the sender and the childViewExpandingEventArgs  objects, but with no results until now.

Thank you.

Hello Bruno,

You can get to the ChildRows of the parent row that you are expanding in the following way

this.radGridView1.ChildViewExpanding += new ChildViewExpandingEventHandler(radGridView1_ChildViewExpanding);

void radGridView1_ChildViewExpanding(object sender, ChildViewExpandingEventArgs e)
{
    foreach (GridViewRowInfo childRow in e.ParentRow.ChildRows)
    {
        MessageBox.Show(childRow.Cells["childColumnName"].Value.ToString());
    }
}

Hope that helps
Richard

Thank you for your answer.

Unfortunately, when trying your solution, i find that ParentRow.ChildRows  is null, so I cannot have access to the cells.

Hello Bruno,

What version of the controls are you using? I have tried this with the latest Q3 2010 SP1 release and all works fine.

Richard

Hello,

Sorry, it appeared that we are working with a derived version of Telerik GridView, and some behaviours have been modified.
That's why ChildRow is not initialized.
