Exception during custom sorting 2010 Q2 SP2.

Exception during custom sorting 2010 Q2 SP2.

Hi

2010 Q2 SP2.

 I have random exception when I want sort in grid.

 I do something wrong or there is bug in grid?

 In my scenario I do custom sorting:

 

 

private void radGridView1_CustomSorting(object sender, GridViewCustomSortingEventArgs e)
{
        if (e.Column.Name == "Size")
        {
            SizeObject size1 = e.CellValue1 as SizeObject;
            SizeObject size2 = e.CellValue2 as SizeObject;
            if (size1.Size > size2.Size)
            { e.SortResult = 1; }
            else if (size1.Size < size2.Size)
            { e.SortResult = -1; }
            else
            { e.SortResult = 0; }
        }
        if (e.Column.SortOrder == RadSortOrder.Descending)
        { e.SortResult *= -1; }
    }
}

 

ArgumentException - Insufficient space in the target location to copy the information.

Hello Raymond,

Please try the following example, everything is working as expected, please let me know if you are doing something different:

using System;
    using System.ComponentModel;
    using System.Windows.Forms;
    using Telerik.WinControls.UI;

    public partial class Form1 : Form
    {
        private RadGridView radGridView1 = new RadGridView();

        public Form1()
        {
            InitializeComponent();
            this.Load += new EventHandler(Form1_Load);
        }

        void Form1_Load(object sender, EventArgs e)
        {
            radGridView1.Dock = DockStyle.Fill;
            radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

            this.Controls.Add(radGridView1);
            radGridView1.DataBindingComplete += new GridViewBindingCompleteEventHandler(radGridView1_DataBindingComplete);
            radGridView1.CustomSorting += new GridViewCustomSortingEventHandler(radGridView1_CustomSorting);
            radGridView1.EnableSorting = true;

            radGridView1.DataSource = new ProductsCollection(5000);
        }

        void radGridView1_DataBindingComplete(object sender, GridViewBindingCompleteEventArgs e)
        {
            ((RadGridView)sender).Columns["Size"].CustomDataOperation = CustomDataOperation.Sorting;
        }

            if (e.Column.SortOrder == RadSortOrder.Descending)
            {
                e.SortResult *= -1;
            }

Hello Raymond,

As illustrated by the Emanuel's example, the code snippet you use is not the reason for this issue itself. Since I am not able to reproduce the issue, I would kindly ask you to create a new support ticket and attach your project to it. This will allow me to assist you further.

Best regards,
Alexander

I think I will prepare example with problem in next week...

Hello Raymond,

Feel free to open a new support ticket and send us the sample project when it is ready.

Best wishes,

It is very random issue so it doesn`t hurt me so much.

When I finish more urgent issues in my app I will check this problem…
