Need to diable some controls inside edit form based on some condition

[Pams]

Hi,
I am using radgrid to display user information.( name, position, company, IsExternal, IsPreferred)
Each row will have edit button.
When user clicks edit button, if that user is external user, the all fields will be editable.
If the user is Internal user, then only Ispreferred should be editable, and all other fields should be readonly.

Any help pls,
Thanks,
pams

Hello Pams,

I suppose you are using BoundColumns. Try the following code in ItemCreated event to set ReadOnly for required fields.

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
  if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
  {
       if (UserName == "Internal user")
     {
                GridEditFormItem item = (GridEditFormItem)e.Item;
                TextBox txtbx = (TextBox)item["Name"].Controls[0];
                txtbx.ReadOnly = true;
                TextBox txtbx1 = (TextBox)item["Position"].Controls[0];
                txtbx1.ReadOnly = true;
                TextBox txtbx2 = (TextBox)item["company"].Controls[0];
                txtbx2.ReadOnly = true;
                TextBox txtbx3 = (TextBox)item["IsExternal"].Controls[0];
                txtbx3.ReadOnly = true;
        }
    }
  }

Also check the following help documentation.
Accessing cells and rows.

Note: If you are using TemplateColumns, then access the columns using FindControl method.
