Looking to implement a gridview with a fixed header? I've tried various solutions including this link and this one.
While I've managed to get it working, the main issue lies in the alignment of header width and column width. The scroll and freeze functionality works fine, but visually there's an inconsistency between the header and columns. It seems like when I don't use the freeze logic, the header width appears correctly.
Upon comparing the provided code with mine, I noticed that they defined columns directly in the design, whereas I set them through SQL data source in the code behind. This difference might be causing the width discrepancy.
<form id="form1" runat="server">
<div>
</div>
<asp:GridView ID="GridView1" runat="server" Font-Size=12px CellPadding="4"
ForeColor="#333333" GridLines="Vertical">
<RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
<FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
<HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<EditRowStyle BackColor="#999999" />
<AlternatingRowStyle BackColor="White" ForeColor="#284775" />
</asp:GridView>
</form>
A screenshot clearly illustrates the highlighted problem (notice the disparity in widths).
Could the absence of <th> tags and column names being explicitly specified be the root cause?
If so, how can this issue be resolved? How can I ensure that the header width matches the column width accurately?
Edit:
The rendered HTML page shows some discrepancies compared to the ASP.NET page viewed in the browser. Even with slight differences, the header width issue persists in both versions.
