I have an xml document formated like this that I am populating a grid with using Autogenerated columns.  the Google column does not show as a hyperlink.  is there a way to make the autogenerated hyperlink column?


<?xml version="1.0" encoding="utf-16" ?>

Hello Ted,

I followed your scenario in order to replicate the issue but to no avail. Please find attached a small runnable application, which handles the desired functionality. Give it a try and let me know how it goes or if I am leaving something out.

I hope this helps.

I see what you are doing but I was hoping to get around modifying each row on Itemdatabound (just for performance as this will be a huge amount of data) but Thanks for the example.  I was wondering if with and XML document (not a database) if there was a way to formate the xml to tell the AutoGeneration to make it a hyperlink?

Hello Ted,

Note that runtime auto-generated columns will always appear after the user-specified columns, unless the columns are ordered programmatically.

When the AutoGenerateColumns property is set to true, a GridBoundColumn object is automatically created for each field in the data source. Each field is then displayed as a column in the Telerik RadGrid control in the order that the fields appear in the data source. This option provides a convenient way to display every field in the data source; however, you have limited control of how an automatically generated column field is displayed or behaves.

I hope this information helps.

OK.  this worked fine until I added a detail table to my grid.  now when I first load the grid it shows the linkbutton but when you click and expand to the detailtable, the mastertableview looses the link button formatting.  is there a way to keep this formatting in a hierachical grid?

Hi Ted,

Unfortunately I could not reproduce the issue you are facing. At this point in order to progress in the resolution of this matter, I will ask you to open a formal support ticket and send me a small project. It would allow me to track the issue locally.
As soon as I do I will get back to you with additional information/suggestions.

Best wishes,

Ted, Pravlina,

Did a support ticket get raised for this? If so, what was the outcome?

I ask 'cos this is exactly what I'm seeing.

Yes, I did get it working.  if you are using XML you will want a function similar to this.  hopefully that will help you also.

void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

 

{

 

if (e.Item is GridDataItem)

 

{

BuildLinks(e);

}

}

private static void BuildLinks(GridItemEventArgs e)

{

GridDataItem item = e.Item as GridDataItem;

TableCell tb = item["Google"];

LinkButton lnk = new LinkButton();

lnk.ID = "lnk";

tb.Controls.Add(lnk);

if (item.DataItem != null)

{

XPathNavigator nav = ((IXPathNavigable)item.DataItem).CreateNavigator();

lnk.Attributes.Add("onClick", "javascript:window.open('" + nav.GetAttribute("Google", nav.NamespaceURI) + "');return false;");

}

lnk.Text = "Google";

lnk.Attributes["href"] = "#";

}

Thanks Ted.

Sadly, this doesn't solve my problem in that the links disappear if you interact with the grid.

Back to the drawing board! :-)
