[Solved] How to loop through all controls inside Edit Form Template

[Zinoviy Margovskiy]

Hi Telerik,

I have a Radgrid with EditForm of type "Template".

On Server side at one point I need to traverse through all controls inside the Edit Form  template and their values.
Usually to get a reference to a control I do something like:
         

RadComboBox cntrlDDLhippingAccountType = null;
cntrlDDLhippingAccountType = (RadGrid1.MasterTableView.GetItems(GridItemType.EditFormItem)[0]).FindControl("ddlID") as RadComboBox;

Since, I need to reference all of the controls this time I tried to do the following:

       foreach (Control c in (RadGrid1.MasterTableView.GetItems(GridItemType.EditFormItem)[0]).Controls)
        {
            if (c is RadInputControl)
            {
                ((RadInputControl)c).Text = String.Empty;
            }
            else if (c is RadComboBox)
            {
                ((RadComboBox)c).SelectedIndex = 0;
            }
        }

But this did not work, because Controls collection returns only EditFormTableCell control(s).
So the question is how can I Loop through all editable controls inside Edit Form template and set their values.

Hello Zinoviy,

You need to reference the Controls of the corresponding GridEditFormItem's EditFormCell to traverse the editors in the FormTemplate custom edit form. Hence your code should be modified as follows:

foreach (Control c in ((RadGrid1.MasterTableView.GetItems(GridItemType.EditFormItem)[0] as GridEditFormItem).EditFormCell).Controls)
   {
       if (c is RadInputControl)
       {
           ((RadInputControl)c).Text = String.Empty;
       }
       else if (c is RadComboBox)
       {
           ((RadComboBox)c).SelectedIndex = 0;
       }
   }
