Automatic operations and custom template edit form

[Aleksandar]

To test automatic updates/inserts/deletes, I am using your sample app at: http://www.telerik.com/community/code-library/submission/b311D-kkmhe.aspx
It works fine for AutoGenerated edit form, but not for template form. To reproduce the problem, just paste the following code after closing columns tag (</COLUMNS>):

<EditFormSettings CaptionDataField="Edit contact:" ColumnNumber="2" EditFormType="Template" >
                <FormTemplate>
                <table id="ContactsMiddle" runat="server" style="width:100%; border:none 0px #ffffff; color:#9EB6CE; text-align:left;">
                                    <tr>
                        <td style="width:100px; padding-left:10px" >Last Name:</td>
                        <td style="width:250px;"><asp:TextBox runat="server" EnableViewState="true" Width="70%" ID="inpContactName" Text='<%#Bind("LastName")%>'></asp:TextBox></td>
                        <td style="width:100px; padding-left:10px" >First Name:</td>
                        <td style="width:250px;"><asp:TextBox runat="server" EnableViewState="true" Width="70%" ID="inpContactHomePhone" Text='<%#Bind("FirstName")%>'></asp:TextBox></td>
                    </tr>
                    <tr>
                        <td style="width:100px; padding-left:10px" >Title:</td>
                        <td style="width:250px;"><asp:TextBox runat="server" EnableViewState="true" Width="70%" ID="inpContactEmail" Text='<%#Bind("Title")%>'></asp:TextBox></td>
                        <td style="width:100px; padding-left:10px" >Address:</td>
                        <td style="width:250px;"><asp:TextBox runat="server" EnableViewState="true" Width="70%" ID="inpContactCellPhone" Text='<%#Bind("Address")%>'></asp:TextBox></td>
                    </tr>
                    <tr>
                        <td style="width:100px; padding-left:10px" >Date:</td>
                        <td style="width:250px;"><asp:TextBox runat="server" EnableViewState="true" Width="70%" ID="TextBox1" Text='<%#Bind("HireDate")%>'></asp:TextBox></td>
                        <td style="width:350px; padding-left:10px" colspan="2" >
                            <asp:LinkButton CssClass="lnkSubmit" ID="btnOK" runat="server" CommandName="Update">OK</asp:LinkButton>
                            <asp:LinkButton CssClass="lnkSubmit" ID="btnCancel" runat="server" CommandName="Cancel">Cancel</asp:LinkButton>
                        </td>
                    </tr>

                </table>

                </FormTemplate>

                </EditFormSettings>

The returned error is:

You have specified that your update command compares all values on SqlDataSource 'SqlDataSource1', but the dictionary passed in for oldValues is empty.  Pass in a valid dictionary for update or change your mode to OverwriteChanges.

I see only one example with edit form template on your web site, and that one is using non-standard data source and is visualy very difficult to follow. Not to mention dirty code with ? instead of parameter names and non-maximisable code window.

Please let me know how to use custom template form for automatic operations.

Hello Aleksandar,

Please test the example I attached to this thread. It is a simplified version of our online demo.

I hope this helps.

I'm having a similar layout from the OP at the exception that where you have "First Name", "Last Name" etc.. I'm having labels. I need to access the labels to set the text based on the current user culture.

I'm using ASP.NET AJAX Q3 2010

Edit mode set to: RadGridPersonel.MasterTableView.EditMode = GridEditMode.PopUp;

Here is my edit/insert template;

<EditFormSettings InsertCaption="Add new record" CaptionFormatString="Edit Personnel: {0}" CaptionDataField="FIRST_NAME" EditFormType="Template">

    <FormTemplate>
        <table id="personnelFormTable" cellspacing="1" cellpadding="1" width="400" border="0">
            <tr>
                <td colspan="2">
                    <asp:ValidationSummary ID="ValidationSummary1" runat="server" ValidationGroup="editForm" />
                </td>
            </tr>
            <tr>
                <td>
                    <asp:Label ID="lblFirstName" runat="server" Text="First name"></asp:Label>:
                </td>
                <td>
                    <telerik:RadTextBox ID="rtbFirstName" runat="server" Text='<%# Bind("FIRST_NAME") %>' MaxLength="50">
                    </telerik:RadTextBox>
                    <asp:RequiredFieldValidator ID="rfvFirstName" runat="server" ErrorMessage="Fisrt name is mandatory" ToolTip="Fisrt name is mandatory" ControlToValidate="rtbFirstName" ValidationGroup="editForm">*</asp:RequiredFieldValidator>
                </td>
            </tr>
            <tr>
                <td>
                    <asp:Label ID="lblLastName" runat="server" Text="Last name"></asp:Label>:
                </td>
                <td>
                    <telerik:RadTextBox ID="rtbLastName" runat="server" Text='<%# Bind("LAST_NAME") %>' MaxLength="50">
                    </telerik:RadTextBox>
                    <asp:RequiredFieldValidator ID="rfvLastName" runat="server" ErrorMessage="Last name is mandatory" ToolTip="Last name is mandatory" ControlToValidate="rtbLastName" ValidationGroup="editForm">*</asp:RequiredFieldValidator>
                </td>
            </tr>
             <tr>
                <td>
                    <asp:Label ID="lblLocation" runat="server" Text="Location"></asp:Label>:
                </td>
                <td>
                     <telerik:RadComboBox ID="rcbLocation" runat="server" AppendDataBoundItems="true"
                        DataSourceID="odsLocation" DataTextField="Name"
                        DataValueField="LOCATION_ID" SelectedValue='<%# Bind("LOCATION_ID") %>' onprerender="rcbLocation_PreRender">
                        <Items>
                            <telerik:RadComboBoxItem Text="" Value="" />
                        </Items>
                    </telerik:RadComboBox>
                    <asp:RequiredFieldValidator ID="rfvLocation" runat="server" ErrorMessage="Location is mandatory" ToolTip="Location is mandatory" ControlToValidate="rcbLocation" ValidationGroup="editForm">*</asp:RequiredFieldValidator>
                </td>
            </tr>
        </table>
        <table style="width: 100%">
            <tr>
                <td align="right" colspan="2">
                    <asp:Button ID="btnSave" Text='<%# (Container is GridEditFormInsertItem) ? GetGlobalizedValue("Insert") : GetGlobalizedValue("Update") %>'
                        runat="server"
                        CommandName='<%# (Container is GridEditFormInsertItem) ? "PerformInsert" : "Update" %>'
                        ValidationGroup="editForm" CausesValidation="true">
                    </asp:Button>
                    <asp:Button ID="btnCancel" Text="Cancel" runat="server" CausesValidation="False" CommandName="Cancel">
                    </asp:Button>
                </td>
            </tr>
        </table>
     </FormTemplate>
</EditFormSettings>

From that template I need to set the text for lblFirstName, lblLastName, lblLocation, btnSave and btnCancel.

and here is what I have so far;

protected void RadGridPersonel_ItemCommand(object sender, GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.InitInsertCommandName )
    {
        (RadGridPersonnel.FindControl("lblFirstName") as Label).Text = Resources.RadGrid.Template.FirstName.ToString();
    }
}

RadGrid.Template is a resource file I created and which contains the FirstName etc keys.
However this fail.

What I'm doing wrong? Can someone help please!

Hello Mario,

You can access the Label and set its text in ItemDataBound like below.

C#:

protected void RadGridPersonel_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridEditFormInsertItem && e.Item.OwnerTableView.IsItemInserted)
        {
            GridEditFormInsertItem insertItem = (GridEditFormInsertItem)e.Item;
            Label lb = (Label)insertItem.FindControl("lblFirstName");
            lb.Text = // your value
        }
    }

Thanks,
Princy.

Princy, thank you for your reply. I tried your approach which is similar to a few I did before and worked on other projects. However for that project it leaves the label blank. I have been given that application last week and I fount out that every grid use a base class to perform some routines. Nothing with text thought. I believe this add a round trip to the server and remove everything I can change dynamically from the templates. I've tried from ItemDataBound, ItemCreated and ItemCommand and none works.

When I go like this on the aspx page;

<

 

asp:Label ID="lblFirstName" runat="server" Text="<%# Resources.RadGrid.Template.FirstName %>"></asp:Label>

 

The label retains the value and display properly.

Thanks again for your help :)
