ArgumentOutOfRangeException on Remove All

[George]

I am implementing a RadGrid that lists admin information messages.  Each row has a row delete X and I have a Remove All button.  The single row deletes work fine but the Remove All gives after the delete.

[ArgumentOutOfRangeException: capacity was less than the current size.
Parameter name: value]

I am creating my grid completely from C# code with a very minimal grid definition in the . The remove all looks like this.

protected void RemoveAll_Click(object sender, EventArgs e)
{
    HomeGrid.DataSource = null;
    DataService.Factory().RemoveAllMessages(user.orgId);
    HomeGrid.Rebind();
}

This is my grid definition without the columns

RadGrid adminGrid = HomeGrid;
adminGrid.NeedDataSource += new GridNeedDataSourceEventHandler(AdminGrid_NeedDataSource);

adminGrid.Skin = "Default";
adminGrid.AutoGenerateColumns = false;
adminGrid.EnableViewState = false;
adminGrid.GroupingEnabled = false;
adminGrid.AllowPaging = true;
adminGrid.PageSize = 500;
adminGrid.Height = Unit.Percentage(100);
adminGrid.EnableHeaderContextMenu = true;
adminGrid.AllowSorting = true;
adminGrid.AllowFilteringByColumn = true;
adminGrid.AllowMultiRowSelection = false;
adminGrid.AllowAutomaticDeletes = true;

adminGrid.ClientSettings.EnableRowHoverStyle = true;
adminGrid.ClientSettings.Selecting.AllowRowSelect = true;
adminGrid.ClientSettings.Selecting.EnableDragToSelectRows = true;
adminGrid.ClientSettings.ReorderColumnsOnClient = true;
adminGrid.ClientSettings.AllowColumnsReorder = true;
adminGrid.ClientSettings.ColumnsReorderMethod = GridClientSettings.GridColumnsReorderMethod.Reorder;
adminGrid.ClientSettings.Virtualization.EnableVirtualization = true;
adminGrid.ClientSettings.Virtualization.InitiallyCachedItemsCount = 2000;
adminGrid.ClientSettings.Scrolling.AllowScroll = true;
adminGrid.ClientSettings.Scrolling.UseStaticHeaders = true;
adminGrid.ClientSettings.Scrolling.ScrollHeight = Unit.Percentage(100);
adminGrid.ClientSettings.Resizing.AllowColumnResize = true;
adminGrid.PagerStyle.Mode = GridPagerMode.NextPrevNumericAndAdvanced;
adminGrid.GroupingSettings.CaseSensitive = false;

and this my  RadGrid definition

<asp:panel runat="server" ID="HomeGridPanel"  CssClass="windowPercent" >
            <telerik:RadGrid runat="server" ID="HomeGrid"  OnItemCommand="HomeGrid_ItemCommand"></telerik:RadGrid>
</asp:panel>

I looked at other posts and could not figure out anything to do about this.   I added AllowAutomaticDeletes based on searches which did not help.

How can I get rid of the ArrayList ArgumentOutOfRangeException when the Grid goes from having data to no data on a Rebind()?

On removing single rows going from 1 to zero works fine but Remove All gives the error one row.  I think the difference is the single row remove is done from an OnItemCommand RadGrid call while the Remove All is done from a server button click method.

Hi,

Can you please share the"RemoveAllMessages" method declaration and the whole RadGrid  configuration so that we can further research on the problem and advise yo for the possible reason of this error?

It is a simple delete using an SQL statement.

public void RemoveAllMessages(Guid orgId)
{
    if (orgId.Equals(Guid.Empty)) {
        return;
    }
    using (SqlConnection theConnection = GetConnection()) {
        SqlCommand command = null;
        SqlTransaction deleteTransaction = null;
        try {
            theConnection.Open();
            deleteTransaction = theConnection.BeginTransaction();

            command = new SqlCommand("DELETE FROM OrgMessages WHERE Orgaz = @orgId", theConnection, deleteTransaction);
            command.Parameters.Add(new SqlParameter("@orgId", SqlDbType.UniqueIdentifier)).Value = orgId;
            command.ExecuteNonQuery();

            deleteTransaction.Commit();
        }
        catch (Exception ex) {
            DatabaseThrowError(this.ToString(), command, ex);
        }
    }
}

That removes all messages associated with the organisation messages being displayed in the grid. 

The data source for the grid is done with...

protected void AdminGrid_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
{
   HomeGrid.DataSource = DataSource;
}

 

DataSource is an object of type public class AdminHomeData : System.Data.DataTable

The AdminHomeData DataSource object exists and  is empty on the Rebind()..

Considering it feels like an internal bug in the Telerik software, I worked around it by refreshing the page and getting rid of the crashing Rebind() when removing all messages. Removing 1 message rebinds fine.

Hi,

Can you pleas elaborate on how exactly the columns are added to the rad grid control, as i suppose that the programmatically added columns might cause the issue on your end?
