I'm using a wizard control with 4 steps, when I use the previous button to navigate back to the previous step the page reloads but at the bottom of the page.Instead of showning the whole of the page, the user views the footer of the site and the previous button and next button.I'm sure there is a very simple answer to this but I just can't figure out how to get the page to reload to the top.

View 2 RepliesI have a special requirement with regards to popping up a MsgBox in ASP.Net. There seems to be various solutions across the Internet using the Javascript confirm box, and passes the response to a hidden control, from which VB.Net can the read and further respond ...but the Javascript code is initialted by a button on the ASP.Net Form. I want to be able to pop-up a MsgBox in the middle of my VB code-behind using the Javascript trick, which passes the result to the hidden control, which can then be read by VB.Net .... the problem is that the page has not refreshed and the hidden control still contains the value from the previous Submit .... I'll attach my code. If anyone can come up with a solution, will you have achieved the impossible!

I am trying to build myself a grid that displays some very simple data (a name and a price of food items on a menu) which the user can very easily edit. The idea is that the grid is always editable, and editing, deleting, adding a new row and hopefully swapping two rows can be done without posting back to the server (at all, not even in an update panel or something).
So far I managed to get deleting to work, but it requires a bit of an explanation. I have a pretty good idea of how to implement adding new rows so I will try that myself. The problem at the moment is swapping rows.
First of all, the data I am displaying in the grid are instances of the MenuItem class, which has properties:
Id (integer, unique identifier)Name (string)Price (float)
I'll explain this step by step:

The grid is a GridView with 6 rows: ....

I've written a web user control which I want to be able to drop into the markup for either aspx pages or other web user controls.I need my user control to be able to easily and efficiently work out if its inside another user control or an aspx page. My initial idea is to do it recursively with checks on the Parent property - continue looking up the nesting hierarchy until I find either a web form or a user control - but I'm not sure this the best way of going about this.
View 3 RepliesIs there a simple way to find a control in ASP.NET by id (in any nested container)? Other than traversing whole controls tree.
Something like this example:
TextBox tb = new TextBox() { ID = "textboxId"};
panel3.Controls.Add(tb);
And in other method/class:
TextBox nameTextbox = MethodToFindControl("textboxId") as TextBox;
I am loading a control to a page dynamically with LoadControl("src to file"). In the usercontrol i have a validator and some other controls that i would like to access from my page. I canät get it to work, null pointer exception. Scenario is like this. I have a Edit.aspx page which loads the EditTemplate.ascx usercontroll. I would like to get information or find the controls in the EditTemplate from the Edit.aspx site. I have tried exposing the controls and validators as properties but how do i access them from my Edit.aspx?
Example code:
Edit.aspx, the control is later added into a
Control control = LoadControl("src to ascx");
TemplatePlaceHolder.Controls.Add(control);
EditTemplate.ascx
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="CompanyImageFile" ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator>
CodeBehind
public partial class EditTemplate : System.Web.UI.UserControl, IEditTemplate {
public RequiredFieldValidator Validator {
get { return this.RequiredFieldValidator1; }
set { this.RequiredFieldValidator1 = value; }
}
From the Edit.aspx site i would like to check the validators isValid property. Isvalid is set in a Save method. The save button that saves the template is located in edit.aspx, so the post in done from that page. So the question is how to get a hold of the property from the usercontrol in the edit.aspx page, where and how should this be done?
