Help with itemcommand

[Venkatesh]

Hi,
I have the below code in Itemcommand. I want to restrict users to enter only 2 rows. And also, if an existing row is deleted and number of rows is within 2, user should be able to add new item. This code is not working

int count = radgrid1.MasterTableView.Items.Count;
                  if (count > 2)
                  {
                      e.Canceled = true;
                      radgrid1r.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.None;

                  }
                  else
                  {
                      radgrid1.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.TopAndBottom;
                  }

Also, i am  clicking on "ADD NEW ITEM" twice to make it disapper.
If the items inserted are 2 then automatically the "add new item" should not be displayed.
How to fix this?

Hi Venkatesh,

Have you tried calling Rebind() for the grid after setting these properties? If you do not want to rebind the control, you can try directly hiding the command item by setting Visible=false.
To access the command items directly, use RadGrid1.MasterTableView.GetItems(GridItemType.CommandItem). This will return a collection of the items.

Hi,

You can take the items count in prerender and hide the commanditem.
C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
   {
        int count = RadGrid1.MasterTableView.Items.Count;
        if (count >=10)
        {
            GridCommandItem cmd = (GridCommandItem)RadGrid1.MasterTableView.GetItems(GridItemType.CommandItem)[0];
            cmd.Visible = false;
        }
}

Thanks,
Shinu.

HI,
Thanks for the reply.
The prerender code is almost fine. I have the "Add new item" command in "Top and Bottom". With the code you provided, it hid only the "Top" one.
How to hide the bottom "Add new item" command also.

Thanks

Hi Venkatesh,

To hide the second command item, you also need to write:

(GridCommandItem)RadGrid1.MasterTableView.GetItems(GridItemType.CommandItem)[1]

In my opinion, it would be a bit better if you first check the length of the collection returned by GetItems and if it is larger than 0, do a foreach loop where you hide each item. This way you do not hard-code the index and are save in scenarios where the command item isn't always there.

Hi,

Try looping through the items as shown below.
C#:

protected void RadGrid2_PreRender(object sender, EventArgs e)
{
    int count = RadGrid2.MasterTableView.Items.Count;
    if (count >= 10)
    {
        foreach (GridCommandItem item in RadGrid2.MasterTableView.GetItems(GridItemType.CommandItem))
        {
            item.Display = false;
        }
     }
}

Thanks,
Shinu.
