[Jaime]

Hello...

Now I'm having problems with EditForm. I have added the following template. When I click the pencil to edit a row of the RadGrid (databounded to a datasource) all TextBox fields appear empty.

Any help woul be greatly appreciated

<EditFormSettings EditFormType="Template">
<EditColumn UniqueName="EditCommandColumn1"></EditColumn>
    <FormTemplate>
        <rad:RadPanelbar ID="pnlUsuario" runat="server" Skin="Default2006" Width="100%" ValidationGroup="grpSeleccion">

Hi Jaime,

How the grid is bound in your case? Are you using DataSourceID?

Hi,

Try using  DataBinder.Eval expressions in the template's definition:

<%# DataBinder.Eval(Container.DataItem, "ColumnName") %>

Thanks,
Princy

Hello !

Vlad:
Yes, I am using DataSourceID bound to an ObjectDataSource.

Princy:
I tried it, but it didn't work.

I used

                            <tr>
                                <td class="label" style="width: 110px">Nombre</td>
                                <td style="width: 250px"><asp:TextBox CssClass="texto" MaxLength="50" Columns="50" ID="txtNombre" Text='<%# DataBinder.Eval(Container.DataItem, "FirstName") %>' runat="server"></asp:TextBox>
                                    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="txtNombre"
                                        ErrorMessage="Debe ingresar el nombre del usuario" SetFocusOnError="True" Display="Dynamic">*</asp:RequiredFieldValidator></td>
                            </tr>

But that text field is still appearing empty when I enter edit mode. Other fact I could mention. If I write the name of a non-existent column, no exception occurs so I suppose the only thing that is happening is to show the form, not to bind the data.

Thanks
Jaime

I have implemented EditCommand of the GridView which actually is called when I press the pencil icon.

By using immediate window I saw the content of e.Item property:

e.Item
{Telerik.WebControls.GridDataItem}
    [Telerik.WebControls.GridDataItem]: {Telerik.WebControls.GridDataItem}
    base {Telerik.WebControls.GridTableRow}: {Telerik.WebControls.GridDataItem}
    CanExpand: false
    ClientRowIndex: -1
    DataItem: null
    DataSetIndex: 19
    Display: true
    Edit: true
    Expanded: false
    GroupIndex: "18"
    HasChildItems: false
    IsDataBound: true
    IsInEditMode: false
    ItemIndex: 19
    ItemIndexHierarchical: "19"
    ItemType: AlternatingItem
    OwnerGridID: "grdUsuarios"
    OwnerID: "grdUsuarios_ctl01"
    OwnerTableView: {Telerik.WebControls.GridTableView}
    RowIndex: 40
    Selected: false

I don't know if this can help to solve the problem, but just in case

I have found the problem !!!

The fact is that I have a RadPanelBar inside the FormTemplate and inside it, I placed the TextBox controls.

To make a test, I placed a TextBox outside the RadPanelBar and the TextBox was correctly filled with the data.

The question now is: how can I use RadPanelBar inside the form template? I need to group the elements that are edited and instead of using HTML tables and implementing expand and collapse by myself, I found RadPanelBar a good alternative.

Thanks
Jaime

Hi Jaime,

When the TextBoxes used in the edit form are nested in another control which runs at server, it is expected that the binding expression does not work properly. Therefore you have to set the textbox controls value in the ItemDataBound event handler of the grid:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
    {
        GridEditFormItem item = e.Item as GridEditFormItem;
        RadPanelBar panelBar = item.FindControl("pnlUsuario") as RadPanelBar;
        TextBox txt1 = panelBar.Items[0].FindControl("txtNombre") as TextBox;
        txt1.Text = (item.DataItem as DataRowView)["FirstName"].ToString();
        ....
    }
}
