View 3 RepliesI have a Datagrid control which is populated with data from an Access database when the page loads - a simple 'Select *' command. This page also contains a text box and a button, the idea being that the user can then filter the data by entering a value in the text box and clicking on the button to pass the new parameter to the datasource.
However, I cannot get this to work, I know it has something to do with 'IsPostback', but I am at a loss. I have tried variations of the following in the code behind page but to no avail.

View 1 RepliesI have one question regarding browser remembering previously entered values. I'm developing ASP.NET MVC 2 application and for some reason my web site suddenly stopped remembering previously entered values in text inputs. I can still see values entered yesterday, but non from today.
I also noticed that my username textbox values started appearing in email textbox although I never changed the name or id of my html elements. The only thing I did was to remove some input elements and added some new... But they all have unique id's and names...
I did a lot of search over the web, but just couldn't find the right answer...
Would it be possible that the model binding could be causing this which I implemented today? Or maybe some web.config configuration?
I have a webform, that needs to check the values entered against a database, and then send an email if the request turns out positiv.

View 2 RepliesIn a aspx page I am displaying records in the datagrid control. I have added one more column to the datagrid in my aspx page and this column is the template column which contains the checkbox control for each of the records. Then I have two buttons a) Display and b) submit
When i click Display button I get all the records in the datagrid from the database(about 700 rows). Then when I click the checkbox for a few rows and click the Submit button then it redirects to another aspx page (i have given response.redirect) . But sometimes when i click a few rows and then click the submit button the screen goes completely blank and it even does not redirect to the next page as specified(in the browser URL the initial page name is only shown).

I want to dynamically bind dataset values into datagrid's header datafield.
Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.
i.e like ds.Tables[0].Rows[0][0].
Is it possible to do it in Datagrid ItemDataBound function like,
e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]
or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.
