How to perform different actions on controls for Editing and Inserting? EditFormType is Template.

[GrZeCh]

Hello!

I have DropDownList control in my FormTemplate and I want to perform different actions for this control while Editing and Inserting. How can I do that?

EditFormType is Template

Thanks in advance

already been there and I had problem with accessing controls in EditForm under ItemCommand event. Can You maybe give me an example?

Hi,

Try accessing the DropDownList control  in the ItemDataBound event as shown below.

CS:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {

        if ((e.Item is GridEditFormItem) && (e.Item.IsInEditMode))
        {

            GridEditFormItem edititem = (GridEditFormItem)e.Item;
            DropDownList ddl = (DropDownList)edititem.FindControl("DropDownList");
        }
   }

Thanks
Princy.

It works but how can I check what action is performed (editing or adding new item)?

Hello GrZeCh,

I think that the information from this help article will help you determine the edit/insert mode inside the ItemCreated/ItemDataBound handlers of RadGrid:

Yes. Thats exactly what I needed.

Few minutes ago I solved my problem using this:

                if (e.Item.DataItem is GridInsertionObject)
                {

                }
                else if (e.Item.DataItem is DataRowView)
                {

                }

but I use code from URL given by You

Hi there...
Inserting data is not a problem.
But when I update the data, there's an error : "Object reference not set to an instance of an object"

My ASPX :

                <EditFormSettings CaptionFormatString="Rubah Project: {0}" CaptionDataField="nama_proyek_en" EditFormType="template" FormTableStyle-Width="600">
                 <PopUpSettings ScrollBars="None" />                              
                  <EditColumn ButtonType="ImageButton" InsertImageUrl="~/images/icon_ok.gif" EditImageUrl="~/images/icon_ok.gif" CancelImageUrl="~/images/icon_cancel.gif" EditText="Ubah" HeaderText="Silakan merubah data proyek :" UniqueName="EditCommandColumn1" UpdateText="Simpan">
                  </EditColumn>                                                    
                  <FormTemplate>
                    <table border="0">
                        <tr>
                            <td style="width:120px;">Nama Proyek (English)</td>
                            <td>:</td>                           
                            <td><telerik:RadTextBox ID="txtNamaProyekEn" runat="server" Text='<%#IIf(DataBinder.Eval(Container.DataItem, "nama_proyek_en") Is DBNull.Value, "", Eval("nama_proyek_en"))%>' EmptyMessage="Masukkan nama proyek dlm Bahasa Inggris" Width="200" MaxLength="150" ></telerik:RadTextBox></td>
                        </tr>
                        <tr>
                            <td style="width:120px;">Nama Proyek (Indo)</td>
                            <td>:</td>
                            <td><telerik:RadTextBox ID="txtNamaProyekID" runat="server" Text='<%#IIf(DataBinder.Eval(Container.DataItem, "nama_proyek_id") Is DBNull.Value, "", Eval("nama_proyek_id"))%>' EmptyMessage="Masukkan nama proyek dlm Bahasa Indonesia" Width="200" MaxLength="150" ></telerik:RadTextBox></td>                           
                        </tr>
                        <tr>
                            <td style="width:120px;">Lokasi Proyek</td>
                            <td>:</td>
                            <td><telerik:RadTextBox ID="txtLokasi" runat="server" Text='<%#IIf(DataBinder.Eval(Container.DataItem, "location") Is DBNull.Value, "", Eval("location"))%>' EmptyMessage="Masukkan lokasi proyek" Width="150" MaxLength="100" ></telerik:RadTextBox></td>                           
                        </tr>
                        <tr>
                            <td style="width:120px;">Tanggal</td>                           
                            <td>:</td>                           
                            <td><telerik:RadDatePicker ID="txtTanggal" runat="server" SelectedDate='<%#IIf(DataBinder.Eval(Container.DataItem, "tanggal") is DBNull.Value, Datetime.now, Eval("tanggal")) %>'  Skin="WebBlue"></telerik:RadDatePicker></td>
                        </tr>
                        <tr>
                            <td colspan="3">
                                <asp:ImageButton ID="imgSave" runat="server" ImageUrl="~/images/icon_ok.gif" CommandName='<%# IIf( DataBinder.Eval(Container, "OwnerTableView.IsItemInserted"), "PerformInsert", "Update") %>' ToolTip='<%# IIf((TypeOf(Container) is GridEditFormInsertItem), "Tambah", "Ubah")%>' />
                                <asp:ImageButton ID="imgCancel" runat="server" ImageUrl="~/images/icon_cancel.gif" CommandName="Cancel" ToolTip="Batal" />
                            </td>
                        </tr>
                       
                    </table>
                  </FormTemplate>
                </EditFormSettings>

Here is My VB :

Protected Sub rgAll_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles rgAll.ItemDataBound

If TypeOf e.Item.DataItem Is GridInsertionObject Then

            Dim objEditFormItem As GridEditableItem = CType(e.Item, GridEditableItem)

            Dim sqlProjectAdd As New SqlCommand("sp_ProjectAdd", myConn)
            sqlProjectAdd.CommandType = Data.CommandType.StoredProcedure
            sqlProjectAdd.Parameters.AddWithValue("@nama_proyek_en", CType(objEditFormItem.FindControl("txtNamaProyekEn"), RadTextBox).Text)

            Try
                myConn.Open()
                sqlProjectAdd.ExecuteNonQuery()
                myConn.Close()
                rgAll.DataBind()
            Catch ex As SqlException
                lblInfo.Text = "Error saving data : " & ex.Message & "<br \>"
                lblInfo.Visible = True
            End Try
            myConn.Close()

        ElseIf TypeOf e.Item.DataItem Is DataRowView Then

            Dim editedItem As GridEditableItem = CType(e.Item, GridEditableItem)

            Dim sqlProjectEdit As New SqlCommand("sp_ProjectEdit", myConn)
            sqlProjectEdit.CommandType = Data.CommandType.StoredProcedure
            sqlProjectEdit.Parameters.AddWithValue("@project_code", rgAll.MasterTableView.DataKeyValues(e.Item.ItemIndex)("project_code").ToString)
        sqlProjectEdit.Parameters.AddWithValue("@nama_proyek_en", CType(editedItem.FindControl("txtNamaProyekEn"), RadTextBox).Text)

            Try
                myConn.Open()
                sqlProjectEdit.ExecuteNonQuery()
                myConn.Close()
                rgAll.DataBind()
            Catch ex As SqlException
                lblInfo.Text = "Error saving data : " & ex.Message & "<br \>"
                lblInfo.Visible = True
            End Try
            myConn.Close()
        End If
End Sub

The error comes when I tried to get the value from :
CType(editedItem.FindControl("txtNamaProyekEn"), RadTextBox).Text

Can someone tell me where do I miss?

Hello Anto,

Based on the code snippet, it is hard to determine what is causing the exception at your end. To further address the issue, it will be best if you open a formal support ticket, and send us a small project sample, demonstrating the behavior.
We will review it locally, and advise you further.

Best wishes,
