Automatic updates with Usercontrol

[Steve Y]

I noticed that there's a new feature within RadGrid in the latest release: Q3 2008 SP1 (Version Number 2008.3.1125)

RadGrid

What’s New:

• Added support for automatic updates with UserControl edit form type if the control implements IBindableControl

Does this mean that a usercontrol edit form can now use standard controls with Bind i.e.

<%` Control Language="C#" AutoEventWireup="true" CodeFile="ucTestGrid.ascx.cs" Inherits="UserControls_ucTestGrid" %>

<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("FirstName") %>' TabIndex="1" />
<asp:TextBox ID="TextBox2" runat="server" Text='<%# Bind("LastName") %>' TabIndex="2" />

<asp:button id="btnUpdate" text="Update" runat="server" CommandName="Update" />
<asp:button id="btnInsert" text="Insert" runat="server" CommandName="PerformInsert" />
<asp:button id="btnCancel" text="Cancel" runat="server" causesvalidation="False" commandname="Cancel" />

I tried it but could not get the grid to actually perform the update. When I click edit in the grid, it pops up the edit usercontrol with the two textboxes displaying the actual text from the selected row. When I change one of the values and click update, the popup box seems to behave properly (i.e. it closes), there's now error thrown, but the row in the original grid is not updated.

I'm using a simple test grid and a Linq Data Source with inserts, updates and deletes enabled. My Grid has auto updates etc enabled too.

Either my assumption that this is now possible based on the 'what's new' change is mistaken or I've messed up my code.

Any thoughts?

Thanks, Steve

Hello Steve,

Can you post your IBindableControl implementation? Please check the demo from this blog post for more info:

Vlad,

Thanks for the link to the example. I followed it and finally realized I had not named the textbox IDs the same as the field names. Changed my code and it all works perfectly.

Thanks. Steve

I'd like to do the same but with Manual update.

like in :

    protected void rgCA_UpdateCommand(object source, GridCommandEventArgs e)
    {
        GridItem editItem = (GridItem)e.Item;
        vPersonneDetail cm = GridData[ItemIndex(editItem)];
        cm.PersonneNom = (editItem.FindControl("PersonneNom") as RadTextBox).Text;

        //Assign_rgCA(ref cm, e);
        //GridData.RemoveAt(ItemIndex(editItem));
        //GridData.Insert(ItemIndex(editItem), cm);
        //e.Item.Edit = false;
    }

When I arrive at the line
cm.PersonneNom = (editItem.FindControl("PersonneNom") as RadTextBox).Text;
Find Control return null
 (GridData is my RadGrid1.DataSource of type List<vPersonneDetail>)

Thanks!

Hello Alexandre,

Review the implementation from the following online resources to learn how to perform manual updates with WebUserControl custom edit form:
