[Solved] Can't get RadGrid's ExtractValuesFromItem to work

[bemara57]

I'm a little new at this- but I'm trying to update my MembershipUser via the built-in EditForm in the RadGrid, but it's not taking any of my edits. It doesn't produce any errors, it just updates the user with the same exact info as before, ignoring my changes. What am I doing wrong? I'd greatly appreciate any help or direction.

    protected void RadGrid1_UpdateCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
    {
        // Get edited row
        GridEditableItem editedItem = e.Item as GridEditableItem;

        // Get primary key of editted item
        object dataKey = editedItem.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["ProviderUserKey"];

        //Locate the changed row in the data source
        MembershipUser liveUser = membershipProvider.GetUser(dataKey, false);

        // Check if user still exists in data source
        if (liveUser == null)
        {
            statusLabel.Text += "Unable to locate the user for updating.";
            e.Canceled = true;
            return;
        }

        // Update new values
        Hashtable newValues = new Hashtable();

        // The GridTableView will fill the values from all editable columns in the hash
        editedItem.OwnerTableView.ExtractValuesFromItem(newValues, editedItem);

        try
        {
            // Update user object with form data
            liveUser.Email = (string)newValues["Email"];

            membershipProvider.UpdateUser(liveUser);
            statusLabel.Text += "User " + liveUser.UserName + " updated.";
        }
        catch (Exception ex)
        {
            statusLabel.Text += "Unable to update user. Reason: " + ex.Message + ".";
            e.Canceled = true;
        }

        // Refresh grid view data
        RadGrid1.Rebind();
    }

Hello bemara57,

Rebinding the Grid is not necessary. You can comment the last line to check if this is causing the problem.

Otherwise the example online here:

http://www.telerik.com/DEMOS/ASPNET/Prometheus/Grid/Examples/DataEditing/ExtractValues/DefaultCS.aspx

seems to update the Grid records. I hope comparing the code will help you resolve the problem.

Thanks but I found that it was a timing issue. First I did this (which made the grid go all blank when I clicked anything like the edit button):

    protected void Page_Load(object sender, EventArgs e)
    {    
        if (!Page.IsPostBack)
        {
            RadGrid1.DataSource = membershipProvider.GetAllUsers();
            RadGrid1.DataBind();
        }
    }


I had to do this to get it working:
    protected override void OnPreRender(EventArgs e)
    {
        RadGrid1.DataSource = membershipProvider.GetAllUsers();
        RadGrid1.DataBind();

        base.OnPreRender(e);
    }
