[Solved] Working with data bound columns

[Michael Dunbar]

I am creating a grid programmatically:

RadGrid gridFileView = new RadGrid();
gridFileView.ID = gridFileViewID;
gridFileView.Skin = "Vista";
gridFileView.AllowPaging = true;
gridFileView.PageSize = 20;
gridFileView.AllowSorting = true;
gridFileView.ClientSettings.AllowRowsDragDrop = true;
 gridFileView.ClientSettings.Selecting.AllowRowSelect = true;
pnlFileView.Controls.Add(gridFileView);

AddExistingFiles(gridFileView, docs);

 and am creating the columns with the following code:

private static void AddExistingFiles(RadGrid gridFileView, ExternalDocuments docs)
    {
        // Bind files to grid
        gridFileView.DataSource = docs;
        gridFileView.AutoGenerateColumns = false;
        gridFileView.MasterTableView.DataKeyNames = new string[] { "Guid" };

        AddGridRow(gridFileView);

        gridFileView.DataBind();
    }

    private static void AddGridRow(RadGrid gridFileView)
    {
        GridBoundColumn boundColumn;

        boundColumn = new GridBoundColumn();
        boundColumn.DataField = "DocumentType";
        boundColumn.HeaderText = "Type";
        gridFileView.MasterTableView.Columns.Add(boundColumn);

        boundColumn = new GridBoundColumn();
        boundColumn.DataField = "Uploaded";
        boundColumn.HeaderText = "Date added";
        gridFileView.MasterTableView.Columns.Add(boundColumn);

        boundColumn = new GridBoundColumn();
        boundColumn.DataField = "Title";
        boundColumn.HeaderText = "Title";
        gridFileView.MasterTableView.Columns.Add(boundColumn);

        boundColumn = new GridBoundColumn();
        boundColumn.DataField = "Filename";
        boundColumn.HeaderText = "File";
        gridFileView.MasterTableView.Columns.Add(boundColumn);

        boundColumn = new GridBoundColumn();
        boundColumn.DataField = "Description";
        boundColumn.HeaderText = "Description";
        boundColumn.AllowSorting = false;
        gridFileView.MasterTableView.Columns.Add(boundColumn);

        boundColumn = new GridBoundColumn();
        boundColumn.DataField = "FileSize";
        boundColumn.HeaderText = "File size";
        boundColumn.AllowSorting = false;
        gridFileView.MasterTableView.Columns.Add(boundColumn);
    }

I would like to get the DocumentType data bound column and replace the text with an image based on what that text is. Any ideas on how I go about approaching this?

Thanks,

Michael

No suggestions anyone?

Hi Michael,

Try setting the UniqueName property for the Grid column. Access the Grid cells in the ItemDataBound event using the column's UniqueName and then add the image to grid cell depending on the text.

CS:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {

        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            string strtxt = item["DocumentType"].Text;
            if (strtxt == "test")
            {
                Image img = new Image();
                img.ID = "image1";
                img.ImageUrl = "Images/img1.gif";
                item["DocumentType"].Controls.Add(img);
            }
        }
  }

Thanks
