Rad Grid event event output

Question

Can someone tell me what is happening in this section? Why does this make the elements invisible?

protected void rgStateTax_PreRender( object sender, EventArgs e )
    {
        if( rgStateTax.MasterTableView.IsItemInserted )
        {
            foreach( GridItem item in rgStateTax.Items )
            {
                item.Visible = false;
            }
        }

        if( rgStateTax.EditItems.Count > 0 )
        {
            foreach( GridDataItem item in rgStateTax.Items )
            {
                if( item != rgStateTax.EditItems[0] )
                {
                    item.Visible = false;
                }
            }
        }
    }

here rgStateTax is the radar grid, and PreRender is the event before the page actually appears on the screen, right?

Answer 1

Yes, PreRender is called before the control for the page is displayed.

This piece of code simply iterates over almost every element in the grid and makes it invisible.

if( rgStateTax.MasterTableView.IsItemInserted ) This checks if the element has been inserted into the grid.

foreach( GridItem item in rgStateTax.Items ) This goes through each element in the radgrid.

item.Visible = false; This means that every element is invisible.

Regarding the next part:

if( rgStateTax.EditItems.Count > 0 ) , .

foreach( GridDataItem item in rgStateTax.Items ) radgrid ( , ).

if( item != rgStateTax.EditItems[0] ) , ( , .

item.Visible = false; , .
