View 6 RepliesI have a GridView on a page for maintainance of the database (mdf). Under this GridView1 I have a FormView1 where I use the ItemInsertTemplate to Insert new rows in my database (which shows the data in GridView1). The first textbox (BIDTextBox) i have on this template, contains text which identify a person. I would like to have a routine which checks if the same value that is entered in the BIDTextBox allready exists in the database. This routine should be fired upon leaving the control BIDTextBox.
I have tried with some stored procedure in my database, but that dosn't seem to do the trick. The most logical to me seems to do a loop thru my table "Ansatte" in my database using sql, selecting any occurence from the field "BID" in my table "Ansatte" that is simillar to the text entered in the BIDTextBox.
i want to allow user to select only one row at a time in gridview by selecting a chechkbox.

My scenario was different from the other. my data source is bind to a datatable, all is in hard code.

I have 5 user controls in a web form. Data is being loaded into the user controls at the user control page load event. I have a single save button for the entire web form(the the top of the page). Each user control has update panel and consists of many web controls like textbox, dropdown,gridview and many other.
after the page has been rendered successfully to the user.
Considered that he has changed text in one user control ( in few textboxes,dropdowns , grid) and clicked on save button.
Now I should save only the changes user has made ( in 1 user control) instead of saving all the 5 user controls.
how can i achieve this?

View 2 RepliesI have a gridview that returns several records for the same user and each record has a column with a check box. I need to allow the user to choose only one to check. Also one check box is always supposed to be checked. What is the best way to do it? I was thinking of writing a stored procedure that checks if only one is checked, and then returns true or false. I think there is a more efficient way to do it...
