I have a GridView bound to an ArrayList of Custom Objects. I have a button as part of each row, which when clicked, I delete the row from the Arraylist, and re DataBind() the GridView. While this deletes the Row, it causes the Page to be refreshed that takes the User back to the top of the Page.
E.g. If the User clicks on the button of a row at the bottom of the Page, after the deletion, the Page gets refreshed and the User is now taken to the top of the Page.
This is irritating especially in long lists i.e. GridView with many rows. (I don't want to use paging here.) Is there any way to avoid this, or mitigate this problem.

I have a page with lots of panels on it. Some of the panels are user controls and some are just on the page. I have a form on the page where you can add users and a gridview which is a user control showing a list of users.When a new user is added on the form I want to do gridview.databind() for the gridview in the user control. Does anyone know how to do this?

I have a master template that all the pages on my site use. In the template there is an empty panel. In the code-behind for the page an imagebutton is created in the panel dynamically in my Page_Load section (makes a call to the DB to determine which button should appear via my controller). On some pages that use this template and have forms on them, pressing the Enter key fires the click event on this imagebutton rather than the submit button in the form. Is there a simple way to prevent the imagebutton click event from firing unless it's clicked by the mouse? I'm thinking a javascript method is a hack, especially since the button doesn't even exist in the master template until the button is dynamically created on Page_Load (this is ugly since I can't simply do <% =btnName.ClientId %> to refer to the button's name in my aspx page).I tried setting a super-high tabindex for the image button and that did nothing. Also set the button to be the DefaultButton in its panel on the master template but that did not work either. Moreover, I don't want to add a property to all of my pages that use this template (there are hundreds). It would be optimal to find a solution that works globally from my master template.I'll try to show our example here:We have a button on the top of each page in our system that lets you star the page as one of your favorites, sort of a server-side bookmark system. When the page loads it looks to see if the page is one of your favorites or not and then shows a gold star if it is, and a gray star if it is not. Clicking the imagebutton of a star toggles the page favorite status.In my master template (FullMenu.master) I have this panel
<asp:Panel runat="server" ID="pnlFavorite" style="display:inline;"></asp:Panel>
Next there is a class which creates the button and adds it to the panel on the master template:
public void InsertStarButton()
{
CreateStarButton();

View 3 RepliesWhat is the best solution for adding Textbox controls dynamically to a page when a button is pressed?
The secnario is: "The page initially loads with 3-4 textboxes already displayed but the user needs another textbox added. They click add textbox and another textbox control appears."
I would hope to be able to do this within a updatepanel and use AJAX async postback.
- I'm using a RequiredFieldValidator to check whether the text box is empty. I only wanted this validation to run when I press one specific button.
- I dont want the validation to be done on every button control within a page. For example, i have 2 buttons, one is showing a list of data and another will be checking for an empty text boxes. So, when I click the show list button, I dont want the validation to be run, what I want is the validation to be run on the check empty text boxes button.
I have an ASP.NET GridView that has four columns. The first three are typical BoundField elements bound to a DataTable. The forth is a TemplateField element that I create a DropDownList in on the OnRowCreated event for the GridView.
What I'm attempting to do is walk down the data source for the GridView when a button is pressed. I really just need to get the values for columns one and four of each row. The first three columns have data as expected but the forth is displaying as empty. Is this because it wasn't a part of the DataTable originally? Is there any way to get the value for each drop down as I've described it, or will I need to rework this so each drop down list is a part of the DataTable?
