I have three controls a textbox, a drop down and a check box on a webform as below;
[Code]....
I have an SqlDataSource defined and configured with SELETC and UPDATE commands as below;
[Code]....
How can I;
1. Query the SqlDataSource for a specific record (ie ApplicantID = some value) and then read the selected data in the three controls on the webform?
2. Update user changes from the three webform controls back to the SqlDataSource?

i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?

I just need to know how to select in c# select from my sql server database for the purpose of seeing if data already exists.. do not need to display the data (i know how to select the data and display it in a data grid) but I am checking to see if dates are already in the database before performing an insert since there can not be duplicate dates... it is late but I only can figure out how to use the data as it applies to viewing or if bound to a control. Also I am not using the aspx... in tags... my c# is seperate... do I have to use a stored procedure just to see if the row exists???

As I understand the "gridview" control has a select link that can be enabled, I am fairly new to web development but what I was hoping to do was to click on the select link and then have the record that I have selected display on a seperate webpage. Is this relatively easy to do? Can anyone point me in the right direction?

I have a web page which has about 11 gridviews.Hence the page takes bout 15 seconds to load.The grids are 1 below the other.They are populated at the page load.
I need a solution to reduce page load time. Is there a way,where the gridview loads only if user scrolls to it. I donot want the user to make selection for everytime he wishes to see a gridview. The page should show gridview if its data is bound to it, not waiting for entire page gridviews to get populated.

I'm trying to get a link to load a new page that passes a value to the new page. To my dismay I've found out (or im doing it wrong) that this doesn't work in the repeater.

How would i get something like that to work in my repeater so it can show a new News page with more information on it.

I have a shopping cart and when someone views an item and then returns to the gallery I want it to be on the page they left. Right now I set a session equal to the page and then try to look for it in the page load. My problem is that I select an item and then click back to gallery and it seems to take me to a random page. You can view this at [URL] go to gallery, select an item and then go back to the gallery. here is the page load code.
if (Session["Page"] !=
null)
{
DataPager dp = (DataPager)lvGallery.FindControl("DataPager1");
int iPage = (int)Session["Page"];
dp.SetPageProperties(iPage, dp.MaximumRows, true);
}

I want to insert a record in the gridview and i have designed it as the fig: below shows.
Initially there is no data in the datatable to which the gridview is bound to,so the gridview is not displayed when the page load,ok
I want to ask that is it possible to display Gridview on page load with only the header and the footer?
i.e;the user can see the header names and the textbox and drop down list at the foorter so that they can insert data in the grid?

I have a GridView and a FormView on the same page. They both have separate DataSources. This is a simple Master Details configuration, when a someone clicks on the Select link in the GridView, the FormView brings up the Details data. But for some reason the FormView's DataSource is trying to retrieve data when I load the page. This is causing an error because no ID is passed from the GridView.
