Web form page load event


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.

displaying 2 alternating db records with each new page load event


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)
                 string sql = "select propID from featured_properties where " +
                    "dtDisplay <= '" + today + "' and " +
                    "lastDisplay >= '" + today + "'";

Creating a custom drop down field type with SelectedIndexChanged Event

Hi All, I am trying to create a custom drop down field type and I was able to acheive that using the MS link http://msdn.microsoft.com/en-us/library/bb861799.aspx. As per the link, once the custom field is created we can override the "Validate" method to write the Validation logic and that works fine for me too. However I am facing a challenge even before going to Validate . Let me explain my actual requirements here. I need to build a custom drop down field and expose the field to the user in "Edit Properties " Page of a document library. Along with this field, I will be having some OOB site columns in the Edit Properties Page (Ex: Title, Subject etc)  . When user selects a value in the drop down, I need to hide/show few OOB site columns based on certain criteria.  I am facing a challenge of how to capture the "SelectedIndexChanged " event for the Custom drop down field in Sharepoint (Can we wire the SelectedIndexChanged event to a custom dropdown field type) ? Is this acheivable in SP 2010 Custom field type ? If so, how can I do it ? Can any of you kindly help me here?   Regards, Yesh
