How to add GridButtonColumn (Link Button) to Auto generated grid dynamically

[Tray]

 my requirement is little different. I have a RadGrid (Auto generated columns) on my web page. I’ve got 4 columns all together (From DB). There is a column called “Doc Name”. As I use Auto generate column feature, I get all columns as GridBoundColumns.  I need to change “Doc Name” Grid Bound Column to link button or hyper link column. (Each and every row has a related .PDF file which need to be opened when user click a cell of that column)

Eg:

Doc Name                           Document Title                     Fields                 

Doc 1                                        Drawing 1                             text                   

Doc 2                                         Drawing 1 of 2                     button

Could you please help me to find how to change GridBoundColumn to GridButtonColumn (Link/Hyperlink) in runtime?

Hi,

Try the following code to achieve your scenario.
C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
 if(e.Item is GridDataItem)
 {
   GridDataItem item = (GridDataItem)e.Item;
   HyperLink link = new HyperLink();
   link.NavigateUrl = "Page.aspx";
   link.Text = item["OrderID"].Text;
   item["Doc name"].Controls.Add(link);
 }
}
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
  if (e.Item is GridDataItem)
  {
      GridDataItem item = (GridDataItem)e.Item;
     HyperLink link = new HyperLink();
            link.NavigateUrl = "Page.aspx";
            link.Text = item["OrderID"].Text;
            item["Doc name"].Controls.Add(link);
        }
 }

Thanks,
Shinu.

Hi,

You can access the column using its DataField property. You can change the column to hyperlink as shown below.
C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
 if(e.Item is GridDataItem)
 {
   GridDataItem item = (GridDataItem)e.Item;
   HyperLink link = new HyperLink();
   link.NavigateUrl = "Page.aspx";
   link.Text = item["Doc name"].Text;
   item["Doc name"].Controls.Add(link);
 }
}
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
  if (e.Item is GridDataItem)
  {
      GridDataItem item = (GridDataItem)e.Item;
     HyperLink link = new HyperLink();
            link.NavigateUrl = "Page.aspx";
            link.Text = item["Doc name"].Text;
            item["Doc name"].Controls.Add(link);
        }
 }

Another approach is to add one GridHyperlinkColumn to the Columns property collection of RadGrid. And from code behind hide the corresponding AutoGenereatedColumn for the field 'Doc name'.

Thanks,
Shinu.
