GridView - RowCreated Event Check the Value and Hide Row and Cell Values

This sample code will help you to perform hide and other operation at row level inside the Gridview RowCreated Event.

ASP.NET Code:

<asp:GridView ID="GridViewAllNews" runat="server" DataSourceID="ObjectDataSourceAllNews" 

OnRowCreated="GridViewAllNews_RowCreated"                                                                              DataKeyNames="Id" >
                                                                          

First check if EventArgs is null just return. always check for RowType is DataRow and DataItem is not null.

Find the control using

Image newsImage = (Image)e.Row.FindControl("Image2");

and set the visibility of cell.

C# code:

protected void GridViewAllNews_RowCreated(object source, GridViewRowEventArgs e)
  {
      if (e.Row == null) return;

      // display if 'Visible' = true
      if (e.Row.RowType == DataControlRowType.DataRow && e.Row.DataItem != null)
      {
          bool visible = (bool)DataBinder.Eval(e.Row.DataItem, "Visible");
          e.Row.Visible = visible;
      }

      // display image if a url is specified
      string imageUrl = (string)DataBinder.Eval(e.Row.DataItem, "ImageUrl");
      if (String.Empty.Equals(imageUrl))
      {
          Image newsImage = (Image)e.Row.FindControl("Image2");
          if (newsImage != null)
              newsImage.Visible = false;
      }

   }
