[CSharp]

i try add custom button column as descripted in demo like:

private void AddGridButtonColumn(string name, string uniqueName, bool sortable)
        {
            //remove first if grid has a column with that name
            RemoveGridColumn(uniqueName);
            // Add a new column with the specified name
            GridButtonColumn gridButtonColumn1 = new GridButtonColumn();
            gridButtonColumn1.HeaderText = name;
            if (sortable)
                gridButtonColumn1.SortExpression = uniqueName;
            gridButtonColumn1.UniqueName = uniqueName;
            gridButtonColumn1.DataTextField = uniqueName;

            RadFileExplorer_SharedFolderBrowser.Grid.Columns.Add(gridButtonColumn1);
        }

but no button appears in grid.

Hello CSharp,

I see that you use this demo as base for your code, but I need to examine your full code in order to provide a solution. Could you please open a new support ticket and send me a runnable project that shows your approach and I will rework it in order to make it to work.

I too am trying to get a GridButtonColumn to display in the grid.. none of the examples show a button. All seems to work ok except no button visible

GridButtonColumn gridButtonColumn1 = new GridButtonColumn();
gridButtonColumn1.HeaderText = "View";
gridButtonColumn1.Text = "View";
gridButtonColumn1.Visible = true;
gridButtonColumn1.UniqueName = "View";
RadFileExplorer1.Grid.Columns.Add(gridButtonColumn1);

Hi Ken,

I have already answered your support ticket on the subject, but for convenience I am pasting my answer here as well:

The FileExplore does not allow you to add directly a GridButtonColumn, but you could use the approach shown in this article and add an <input type="button" instead of an <img>. You can directly attach a JavaScript handler to the buttons in order to apply the desired functionality:

in the content provider:

public override DirectoryItem ResolveDirectory(string path)
{
    DirectoryItem oldItem = base.ResolveDirectory(path);
    foreach (FileItem fileItem in oldItem.Files)
    {
        string htmlText = string.Format("<input type='button' value='{0}' onclick='onClickHandler(this);' />", "click me");
        fileItem.Attributes.Add("Button", htmlText);
    }
    return oldItem;
}

The implementation of the  onClickHandler:

<script type="text/javascript">
    function onClickHandler(button) {
        alert("Clicked");
        // your logic
    }
</script>

For your convenience I am attaching a sample project demonstrating the approach.
