Highlighting a row dynamically based on a value

Posted 01 July 2010 - 09:30 PM

I have a label which gets a case number when the page loads.

I have a grid view which shows all the concurrent case numbers. I want to highlight the row in the grid view which has the same case number as in the label. I tried doing it using several methods, but it didn't work, although it compiles fine. Please help me to accomplish this. Pls suggest corrections.
Option 1: using OnRowDataBound as shown in the code below

 <table id = "pt_info_table>
<tr>
<td>CSI Case No :</td>
<td><asp:Label ID="pt_caseNo" runat="server" /></td>
...
</tr>

</table>


<asp:GridView ID="gvConcurrentCases" runat="server"
            EmptyDataText="No Concurrent cases Found"  
        AutoGenerateColumns="False" EnableViewState = "true"  HeaderStyle-Height = "20" RowStyle-Height = "20"
        OnRowDataBound = "gvConcurrentCases_OnDataBound">
        <Columns>
         <asp:TemplateField >
                <ItemTemplate >
                        <asp:CheckBox ID="CheckBoxMerge" runat="server" Enabled="true" />
                </ItemTemplate>
                <HeaderStyle HorizontalAlign="Right" VerticalAlign="Middle" />
                <HeaderTemplate >
                    <asp:CheckBox ID="chkBxHeader" onclick="javascript:HeaderClick(this);" runat="server" />
                </HeaderTemplate>
            </asp:TemplateField>
        <asp:TemplateField HeaderText="Case No.">
                <ItemTemplate>
                <asp:Label ID="LblCaseNo" runat="server" Text='<%# Eval("CaseNo") %>' visible="false"></asp:Label>  
              <a class="link_Concurrent" href='details.aspx?caseno=<%# Eval("CaseNo") %>&ai=<%# Request.QueryString["ai"] %>&pi=<%# Request.QueryString["pi"] %>&ci=<%# Request.QueryString["ci"] %>'>
                <%# Eval("CaseNo") %>
                </a>
                </ItemTemplate>
        </asp:TemplateField>
        <asp:BoundField HeaderText="Case Type" DataField="CaseTypeName" />
        <asp:TemplateField HeaderText="Accession Date" >
            <ItemTemplate>
                <%# completedDateAndStep(DataBinder.Eval(Container.DataItem, "CreatedDate").ToString(), Eval("StepName").ToString())%>
            </ItemTemplate>
        </asp:TemplateField><asp:TemplateField HeaderText="Completed Date" >
            <ItemTemplate>
                <%# completedDateAndStep(DataBinder.Eval(Container.DataItem, "CompletedDate").ToString(), Eval("StepName").ToString())%>
                <asp:Label ID="CompletedStatus" runat="server" Text='<%# Eval("StepName") %>' visible="false"></asp:Label>  
            </ItemTemplate>
        </asp:TemplateField>        
        <asp:TemplateField HeaderText="Note"  >
            <ItemTemplate>
            
            </ItemTemplate>
        </asp:TemplateField>


        </Columns>
        </asp:GridView>       

    <asp:Label ID="Label1" runat="server" ></asp:Label><br />
    <asp:Button ID="MergeReports" runat="server" Text="Batch Save Reports" onclick="MergeReportFiles" />



 protected void Page_PreRender(object sender, EventArgs e)
    {
        getConcurrentCases();
        RemoveCheckBoxes();
        PutCheckMarks();
        
    }

    protected void gvConcurrentCases_OnDataBound(object sender, GridViewRowEventArgs e)
    {

        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (Convert.ToString(DataBinder.Eval(e.Row.DataItem, "CaseNo")) == pt_caseNo.Text.ToString())
            {
                e.Row.BackColor = System.Drawing.Color.Blue;
            }
        }
    }



    protected void MergeReportFiles(object sender, EventArgs e)
    {
        Label1.Text = "          ";
        int NumOfReportsSelected = GetCaseNumsForMerge();
        //if (NumOfReportsSelected < gvConcurrentCases.Rows.Count)
        //    Page.RegisterStartupScript("if (Confirm", "<script language=Javascript>confirm('Not all cases are signed out. Are you sure to continue'));</script>");

        {
            string[] ReportFileNames = GetReportFileNames();
            foreach (string item in ReportFileNames)
            {
                string curFile = item;
                if (!File.Exists(curFile))
                    Page.ClientScript.RegisterStartupScript(Type.GetType("System.String"), "ALERT", "alert('" + curFile.Substring(36) + ": Report Not Found');", true);
            }
            saveMergedFile(ReportFileNames);
        }

    }


Option2: going through each row in the grid and checking the value match
 <table id = "pt_info_table>
<tr>
<td>CSI Case No :</td>
<td><asp:Label ID="pt_caseNo" runat="server" /></td>
...
</tr>

</table>


<asp:GridView ID="gvConcurrentCases" runat="server"
            EmptyDataText="No Concurrent cases Found" 
        AutoGenerateColumns="False" EnableViewState = "true" HeaderStyle-Height = "20" RowStyle-Height = "20">
        <Columns>
         <asp:TemplateField ItemStyle-HorizontalAlign ="Center" ItemStyle-VerticalAlign = "Middle" >
                <ItemTemplate  >
                        <asp:CheckBox ID="CheckBoxMerge" runat="server" Enabled="true"  />
                </ItemTemplate>               
                <HeaderStyle HorizontalAlign="Right" VerticalAlign="Middle" />
                <HeaderTemplate >
                    <asp:CheckBox ID="chkBxHeader" onclick="javascript:HeaderClick(this);" runat="server" />
                </HeaderTemplate>
            </asp:TemplateField>
        <asp:TemplateField HeaderText="Case No.">

There should be a "RowStyle-CssClass" attribute for the GridView. To set that, you would need to do something like this...

<asp:GridView .... 
RowStyle-CssClass='<% Eval("CaseNo") == pt_caseNo.Text ? "css_SameAsCaseNo" : "css_DifferntFromCase" %>' ...>

// the rest of your markup

</asp:GridView>


this hasn't been tested by this is one way to do it. You are basically doing an inline-if statement to determine the CSS class that will be used for the row.

This, of course, would mean that you need to use CSS.

I tried this one also. It did not work.
