[Solved] Adding Button Control to GroupHeader

[Brenda]

Hi,
In my application I would like to add a Button for each group header.
When the user clicks on the Button I want him to be able to insert a new record.
In order for the Insert to work I need to read an ID field value, which is used to Group the records (GroupID).

Here's what I have been able to get so far:
1.I was able to add button to GroupHeader in the Grid's ItemCreated event:
======
if (e.Item is GridGroupHeaderItem)
                {
                    GridGroupHeaderItem groupHeader=         (GridGroupHeaderItem)e.Item;
                   
                    Button objButton = new Button();
                    objButton.CommandName = "Add";
                    objButton.ID = "Button_Add";
                    objButton.Text = "Add ";
                    groupHeader.Cells[0].Controls.Add(objButton);
                   
                }

====

2. Now when the User Clicks on the Button I can get the GroupHeaderItem for which the Button was clicked by interception the ItemCommand Event.

3.I used the FireCommandEvent("InitInsert", string.Empty); to get the Insert input boxes. One problem here is that the Inser section comes on the Last page of the Grid (Paging enabled) can this be fixed?

4. My Main concern is that I am not able to get the GroupID (field in my DB) that is used in GridGroupByField  at design time.
I need this value to be able to insert the record. Is there a way to do this?
I can get this value from the GroupHeader or from any Row in the Group, where the Button was clicked.

Thanks for your help.

Hi,

Try the following code snippet to stop the insert form appearing on the last page of the Grid.

VB:

Private Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.WebControls.GridCommandEventArgs) Handles RadGrid1.ItemCommand
        If e.CommandName = RadGrid.InitInsertCommandName Then
            e.Canceled = True
            e.Item.OwnerTableView.IsItemInserted = True
            e.Item.OwnerTableView.Rebind()
            Return
        End If

Thanks for the Input. I will try the code.
Could you also possible recommend some solution for reading the FieldValue associated to the GroupHeaderItem where I have inserted the Button.
I have mentioned the scenario in my original post.

Thanks,
Brenda.

Hi Brenda,

Try the following code snippet.

CS:

  protected void RadGrid2_PreRender(object sender, EventArgs e)
    {
        foreach (GridGroupByExpression exp in RadGrid2.MasterTableView.GroupByExpressions)
        {
            foreach (GridGroupByField fld in exp.GroupByFields)
            {
                string strField = fld.FieldName.ToString();
            }
        }
    }

Thanks
Shinu.

The code for preventing the insert row from being on the last page of the grid ends up putting the insert row at the top of the current page in the grid.  This is close to what I am looking for, but not quite.  I have the Add New Record button in each Group Header, is there a way to put the Insert row at the beginning or end of the group's rows?

Hi Ryan,

I believe there is no direct way to place the insert form  at the end or beginning of a group. A suggestion though would be to use a NestedviewTemplate and design the insert form accordingly . You can expand the insert form for the first or the last row in the group by looping through the group collection.

Telerik has provide  several properties explained in the link below where you can change the position of the insert form (eg:current page,last page..).
