radfileexplorer custom column sorting

[Billy]

I have a radfileexplorer with three custom columns that are created like this: 

// Sets up a gridTemplateColumn for the Owner

GridTemplateColumn gtcOwner = new GridTemplateColumn();

gtcOwner.HeaderText = "Owner Name";

gtcOwner.UniqueName = "Owner";

gtcOwner.DataField = "Owner";

gtcOwner.SortExpression = "Owner";

rfe.Grid.Columns.Add(gtcOwner);

// Set up a gridTemplateColumn for the upload date

GridTemplateColumn gtcDate = new GridTemplateColumn();

gtcDate.HeaderText = "Date";

gtcDate.UniqueName = "Date";

gtcDate.DataField = "Date";

gtcDate.SortExpression = "Date";

rfe.Grid.Columns.Add(gtcDate);

//Sets up gridTemplateColumn for Visibility

GridTemplateColumn gtcPermission = new GridTemplateColumn();

gtcPermission.HeaderText = "Permission";

gtcPermission.UniqueName = "Visibility";

gtcPermission.DataField = "Visibility";

gtcPermission.SortExpression = "Visibility";

gtcPermission.HeaderStyle.Width = Unit.Pixel(72);

rfe.Grid.Columns.Add(gtcPermission);

When I click the column header the sort icon changes and the content sorts once. Subsequent clicks produce no change. The filename and size columns sort as expected.

Hello Billy,

When creating template columns programmatically, you must create the templates dynamically in the code-behind and assign them to the ItemTemplate and EditItemTemplate properties of the column. I would recommend you to review the following help article which elaborates more on this matter.

I believe the problem is because I'm not creating the grid template columns in the Page_Init() method. Is there a way to grab a column click event and sort client side?

Hi Billy,

Client side sorting is supported only with client side databinding. Please check out the following demos:
Grid - Declarative Binding
Grid - Client-Side Binding and Caching
If you want only to fire the sort command on the client you could use the client side sort() method.
