How can I determine which childrow was click in a heirarchical gridview

[Eddie Harvey]

I have a GridView that has a child template and a relation. I can populate both without an problems at all. When I expand to view the childrows and click/double click one of them I need to open a secondary form that displays some additional data. In order to do that I need to be able to determine the properties of that childrow which was clicked. However, I keep getting the row in the  MasterTemplate... how do I go about this.

Hello Eddie Harvey,

Thank you for your question.

You can find out whether a RadGridView row belongs to the Parent or Child template using the following code snippet:

private void radGridView1_CellDoubleClick(object sender, GridViewCellEventArgs e)
{
    if (e.Row.ViewTemplate == this.radGridView1.MasterTemplate)
    {
        // it is a Parent row
    }
    else
    {
        // it is a Child row
    }
}

I hope it helps.

And if I have a GridView that has a child template and this child template has another child template inside. How can I know if the event click is in the Master, the child or the child inside?

 

Kind regards,

Hello Fernando,

You can use the following recursive method to define the level of hierarchy of each GridViewTemplate:

private void radGridView1_CellClick(object sender, GridViewCellEventArgs e)
{
    int templateLevel = 0;
    GridViewTemplate parentTemplate = e.Row.ViewTemplate.Parent;
    while (parentTemplate != null)
    {
        templateLevel++;
        parentTemplate = parentTemplate.Parent;
    }

    // templateLevel = 0 -> MasterTemplate
    // templateLevel = 1 -> ChildTemplate of the MasterTemplate
    // templateLevel = 2 -> ChildTemplate of the first level ChildTemplate
    // ...
}

I hope it helps.
