How do you get the column index the 'target' was moved TO?

e.Target.OrderIndex is NOT correct for where it was moved TO

Hello Stephanie,

You can use the OnColumnSwapped event: https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/client-side-programming/events/oncolumnswapped. The target column index is where the dragged column will be, so this is the TO index.

If we take the online demo (https://demos.telerik.com/aspnet-ajax/grid/examples/columns-rows/columns/column-row-resize-reorder/defaultcs.aspx) and add that event to it, you will get the behavior you can see in the video attached below.

Note that this works best with the default ColumnsReorderMethod value which is Swap. If you set it to Reorder, the event will fire for each column pair that is swapped for the reorder to take place.

Regards,

Thanks, but I am still having trouble.

First - I am not a fan of the 'swap' version. that seems much less intuitive for our non-tech savvy clients.

Second - how do you get and save those values then? I am using the ColumsReorder method. I have tried many variations, but nothing seems to work. This is what I have now but the order is not changing for our saving method.

    protected void radReport_ColumnsReorder(object sender, GridColumnsReorderEventArgs e)
    {
        RadGrid rg = ((RadGrid)sender);

        for (int i = 0; i < rg.MasterTableView.RenderColumns.Count(); i++)
        {
            for (int c = 0; c < fields.Count; c++)
            {
                // After moved column
                if (fields[c].Column.Equals(rg.MasterTableView.RenderColumns[i].UniqueName))
                    fields[c].ColumnNum = iIndex++; // rg.MasterTableView.RenderColumns[i].OrderIndex - 1;
            }
        }
    }

Hi Stephanie,

When columns are reordered on the server, the Swap method is always used: https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/columns/reordering.

To get the actual index on the server, you must subtract 2 because of the structure columns in the grid as noted in the article above. Nevertheless, I will improve its structure to make this information clearly visible.

Here is a simple example:
