hello,

for all of my grids, i use a custom EditForm of type UserControl. this gives me wonderful design flexibility. however, sometimes i need to do special things in the editform UserControl -- for ex, if our user has read-only access, i need to disable some things.

so, programmatically, how can my hosting ASPX page pass in variables (or set properties, or pass in arguments) on the editform UserControl?


thanks!
matt

Hello Matt,

Check out the following code to access a control in the UserControl EditForm and disable it based on a condition.
cs:
 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e) 
    { 
        if (e.Item is GridEditFormItem && e.Item.IsInEditMode) 
        { 
            if ( user condition
            { 
                GridEditFormItem item = e.Item as GridEditFormItem; 
                UserControl user = item.FindControl(GridEditFormItem.EditFormUserControlID) as UserControl; 
                 TextBox txtbx = user.FindControl("TextBox1") as TextBox;                 
                 txtbx.ReadOnly = true;
                //or txtbx.Enable=false
            }             
        }          
    } 

Thanks
Princy.

princy,

thanks. that may work.

but is there no way to simply pass an argument into the UserControl, so that i can perfom all sorts of things in the UserControl's code-behind?


thanks,
matt

telerik - is there no other way to pass an argument to the EditForm's UserControl? this way i could manage all kinds of private options inside the "fooControl.ascx.cs" class.

thanks,
matt

Matt,

The grid will set DataItem property for your user control (if you have such).
You can use also FormTemplate where you can declare your user control and set any desired property.
