Hi,
I am using the following code to allow fixed headers
ReportView.DataSource = dt;// data table ReportView.DataBind();
ReportView.DisplayLayout.UseFixedHeaders = true;
But I cant see any data in the web grid. However, whe I export to excel, all the data gets exported to excel, which means that the data is there for some reason, its not visible (like setting background, border and forecolor everything to white).
When I comment the last line however, I see the data.
Any help will be highly appreciated.
Thanks,
Sameer
I am having exactly the same problem. I am using the infragistics ver 8.2 CLR 2.0
I tried in the following sequence in the PageLoad (http://forums.infragistics.com/forums/p/3438/19613.aspx#19613), but still it is not working as expected. I even tried to place these attributes in the aspx page, but not working as expected.
this.UltraWebGrid1.Bands[0].Columns[0].Header.Fixed = true;
this.UltraWebGrid1.DisplayLayout.StationaryMargins = StationaryMargins.Header;
I am afraid to try on 8.3 CLR 3.5 because that has another problem with related to StationaryMargins - the grid won't display rows when there is only one record in the data, we have to manually check this condition and set the stationary margin to none. Is there any hot fix for these bugs?!!
Hello,
This one is very weird, I tried again using different versions and all was working fine - here is my setup and you can see my result on the screenshot:
<html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title></title> </head><body> <form id="form1" runat="server"> <igtbl:UltraWebGrid ID="UltraWebGrid1" runat="server"> </igtbl:UltraWebGrid> </form></body></html>using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using Infragistics.WebUI.UltraWebNavigator;using System.Data;using Infragistics.WebUI.UltraWebGrid;public partial class _Default : System.Web.UI.Page { protected override void OnLoad(EventArgs e) { base.OnLoad(e); UltraWebGrid1.DisplayLayout.UseFixedHeaders = true; UltraWebGrid1.DataSource = getTable(); // any sample table UltraWebGrid1.DataBind(); } private DataTable getTable() { DataTable dt = new DataTable(); dt.Columns.Add("Col1"); dt.Columns.Add("Col2"); for (int i = 0; i < 10; i++) { DataRow row = dt.NewRow(); row["Col1"] = "Col1 Data " + i; row["Col2"] = "Col2 Data " + i; dt.Rows.Add(row); } return dt; }}
At this point I believe there are two options:
1) Contact Developer Support directly with the sample project so that they can see if there is something else affecting the grid. Developer Support can be reached here:

2) Download the latest version 2008.3 and give it a try and see how it goes
Thanks for your quick response.
Sorry for not mentioning this earlier, I am using 2007.3 version.
Yes, I have managed to replicate the issue in a very simple case.
I have the following code in the Page Load event
UltraWebGrid1.DisplayLayout.UseFixedHeaders = true; // uncommenting this makes the data visible again
UltraWebGrid1.DataSource = getTable(); // any sample table
UltraWebGrid1.DataBind();
{
DataTable dt = new DataTable();
dt.Columns.Add("Col2");
row["Col1"] = "Col1 Data " + i;
dt.Rows.Add(row);
}
I have not changed a single porperty after adding the grid to the page.
<head runat="server">
</head>
<body>
<form id="form1" runat="server">
<div>
<igtbl:UltraWebGrid ID="UltraWebGrid1" runat="server">
</igtbl:UltraWebGrid>
</div>
</body>
</html>
Am I missing something? I need to demo the Grid capabilities to my manager today, and I really need to get this to work. I appreciate your help.
Hello Sameer,
I am trying to reproduce the problem (using the latest 2008.3) release, but unfortunately to no avail. In every case I tried, UseFixedHeaders worked as expected for this feature and the grid was successfully shown.
Furthermore, it is really weird that UseFixedHeaders has this effect on the grid - are you sure that this is the only line of code the interferes in the scenario? Can you isolate a very simple grid and see how UseFixedHeaders affects it?
