Dear Friends,

Am Fresher to Asp.net, Please can you Clear/Solve my doubt.

I have a GRIDVIEW on My WEBFORM.
I have Displayed Data in GRidview using SQlserver 2005....its fine.

In this GRIDVIEW I have two Columns with Dates..... VALID FROM and VALID TO.

Valid from is cell[4] and Valid to is Cell[5]

Suppose if the date VALID FROM is Greater than VALID TO..... Valid From cell should be blink.

Please can u show me how to do this.

Thanks in Advance.

You will need to apply CSS styles to the cell using an event such as the RowDataBound. I'd suggest looking on google for an example.

suppose you are having two labels in gridview as :

XML

<asp:TemplateField HeaderText="FromDate">
                    <ItemTemplate>
                        <asp:Label ID="lblFromDate" runat="server" Text='<%#Eval("fromdate") %>'></asp:Label>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="ToDate">
                    <ItemTemplate>
                        <asp:Label ID="lblToDate" runat="server" Text='<%#Eval("todate") %>'></asp:Label></ItemTemplate>
                </asp:TemplateField>

Then you compare the two dates in RowDataBound Event using DateTime.Compare function such as:

C#

if (e.Row.RowType == DataControlRowType.DataRow)
        {
            Label fromdate = (Label)e.Row.FindControl("lblFromDate");
            Label todate = (Label)e.Row.FindControl("lblToDate");
            DateTime fdate = Convert.ToDateTime(fromdate.Text);
            DateTime tdate = Convert.ToDateTime(todate.Text);
            
            if (DateTime.Compare(fdate, tdate) > 0)
            {
                fromdate.Style.Add("text-decoration", "blink");
            }.......

get more infomation about DateTime.Compare from google.
Hope this helps.
