how to call dropdown SelectedIndexChanged event in page load event in c#

I have  Web page that uses LinkButton control inside Template Fields of Gridview.

I am trying to work on LinkButton Click event and trying to preserve the Value of LinkButton that user click, and based on that value, i want to refresh tha page data.

I used CommandName and CommandArgument property of Linkbutton, but i can use that property only in GridView_RowCommand method by checking e.CommandName expression. But the problem with that Gridview_RowCommand event fire after all other page_load activity. So the value never used in the page_load event to refresh the data in all other control.

I also tried to use OnClick Method, Session variable and Hidden variable. but when i run Response.Redirect method from Gridview_RowCommand, it clear all the Session and Hidden variable values. also tried (Response.Redirect(,false)) method but never got success.

Any suggestion will be appricated in advance.

        <tr>
    </table>
</asp:Content>

Now in page load ev

I have a webpage which displays content drawn from a single record in a database table. I've been asked to change this so that the content displayed alternates between 2 records each time the page is requested by a browser (I guess this would equate to each PageLoad event).

The records to be displayed are chosen on the basis of two dates, a beginning date and and ending date, that define a time period in which the record is to be active. The table containing these records has 2 columns containing these dates (begin date is contained in "dtDisplay" and end date is "lastDisplay."

I'm not sure how to amend the existing code behind to make this happen. Here is the c# that I inherited from a developer who is no longer available. Thanks for any help:

private void getfeatured_properties()
        {
           string today = DateTime.Now.Date.ToString();

           SqlCommand cmd = common.openDatabase();
           if (cmd.Connection.State == ConnectionState.Open)
           {
              try
              {
                 string sql = "select propID from featured_properties where " +
                    "dtDisplay <= '" + today + "' and " +
                    "lastDisplay >= '" + today + "'";
           

Hello forum,

I have a checkboxlist (cblTeamMates) with a sqldatasource (sqlTeamMates) that has 3 columns (ID, FullName and Status ).  The datavaluefield and datatextfield for cblTeamMates is "FullName" and the 2 status values possible are "Available" and "Absent".  How do I go about, in the page load event,  checking all  the names (FullName) whose Status is "Available"?

Thank you.
