I need to change the readonly property of a asptextbox from the code behind based on certain conditions.
I know how to run a function when the page loads, but I don't know how to reference the form fields to change the readonly property.
Can anyone point me in the right direction?
I would like to set a value:

however, i am also checking if that email already exists, and i want to use the rquiredFieldValidator to show the message, and set the page as invalid.
i've tried the following:
valEmail.IsValid = False
valEmail.Text = "xxx"

the validator itself looks like this:

On the RowDataBound event of a gridview I am setting the name of the HtmlInputRadioButton inside the GridViewRow. The problem is that asp.net automatically makes the name unique therefore ungrouping the radio buttons.
Is there a way that I disable this?
Edit - Here's how I am setting the name:
[code]....
Due to the numbers "106" and "107" in the name of the respective radiobuttons it ungroups them.
I have the following code to playback video clips.. we are getting to the point where i need to get this setup and populated from our table.. i already have the data i need to put into the needed parameters, but cant figure it out.. i have tried to add runat="server" and add an ID to the parameters i need to control, but when the page loads, the video window is displayed, but no video is available. and at the moment i have the video hard coded to test, but will need to replace that with video links stored in the table.. what am i missing or doing wrong?

I'm trying to dynamically create a grid view in C#, the grid will have two columns, one of which is a hyperlink field.Now i've noticed when creating the grid view statically in aspx, the DataNavigateUrlFields property accepts a single string as it's value (the field in the data source with the URL in).
When creating it in code, the very same property is a string[] array, rather than a single string, and is expecting multiple fields which combine together to make the URL (if I've understood MSDN correctly), but what if I just want a single field for the URL?
Why does aspx let me do this, but the C# not?
Here's my code:
Name.HeaderText = "Exercise"; Name.DataField = "Name"; Link.HeaderText = "More Info"; Link.DataTextField = "Link"; Link.DataNavigateUrlFields = "Link";
The code above does NOT compile, I got the following error:
Error 2 Cannot implicitly convert type 'string' to 'string[]' This is regarding the last line.
Here is the aspx code, which it's fine with:
<asp:HyperLinkField HeaderText="More Info" DataTextField="Link" DataNavigateUrlFields="Link" target="_blank" />
Does anyone know how I can dynamically create a hypertext field for a grid view, where it only takes a signle field from the data source as the URL?

View 1 RepliesI am trying to set up my first custom validator in VS 2010 VB. I want it to use a Sub or Function that is in my code-behind. I have searched the WEB but the instructions and examples that I have found do not show me how to use code-behind.
The main problem that I am running into is that I can not find a way to connect the validator to a sub that preforms the validation check.
I created an image button in my header template. When clicked, it calls the Sorting method. When I change the image url in code behind, it does not render. By setting a break point, I can see the property being updated, but I assume it is getting overridden by the default I set in the HTML page.
Code:
<HeaderTemplate>
<span>Claim Id</span>
<asp:ImageButton ID="btnClaimIdSort" runat="server" ImageUrl="~/Styles/UpArrow.ico" OnClick="Sorting" ToolTip="ClaimId" />
</HeaderTemplate>
Code:
protected void Sorting(object sender, EventArgs e)
{
var sortButton = (ImageButton)sender;
// parse new sort
var newField = sortButton.ToolTip;
// parse existing sort
var existingSortArgs = this.ClaimSort.Split(' ')

I have a master page (Site.master) with a navigation menu linked to a datasource (Master.sitemap). I have a nested master page that has another navigation menu. For any item clicked in this nested navigation menu, I want a particular menu item in the Site.master navigation menu to be selected.
Here's my Site.master menu:
[Code]....
In my Site.master.cs I have this:
[Code]....
In the nested master page, Products.master I have this:
[Code]....
In the Products.master.cs file I try to change the selected item.
[Code]....
The master navigation and products navigation menus work just fine by themselves. But when I've tried to set the selected item of the master menu in the Page_Load above, I can't seem to access it. What I've found in trying to do this is the NavigationMenu seems to be uninitialized. The menu Items list is empty. What am I missing here? Why are there no menuItems in the Master.NavigationMenu control?
I have some pages that need user to sign in. If not, I need to redirect user to signin page. I know this can be done by using some code like"<system.web><authorization><deny users="?"/></authorization></system.web>" in web.config.
But can I just write some code to do the same function?
like in page load method, I can check whether user is sign in, if user is not signed in yet, how can I redirect user to the login page by using code? and how can I stop sending the content of the page to user?
I would like to be able to set the EmptyDataText property using code-behind. I have created a custom GridView control called PagingGridView. Here is the definition:
public class PagingGridView : GridView {
}
In my ASPX page, I would created a new GridView definition by doing this:
<cc:PagingGridView id="MyGrid" runat="server" ><cc:/PagingGridView>
When I databind the control, I would like my custom control to automatically detect an empty data source and build a table with all the header columns and a row containing the empty data text. The rendered code for the empty data source would be like:
<table>
<tr>
<td>Col1</td><td>Col2</td>
</tr>
<tr>
<td colspan="2">No Records to display</td>
</tr>
</table>
My initial thought was to override the EmptyDataText property but I could not get that to work.
what I am trying to do is add a method to my gridview's sorting event to add a class to the column being sorted so the user can know if the data is being sorted ascending or descending and on what column. I am currently trying to do it through a switch statement on the sort expression to determine what column it's coming from but I am unaware of how to set the css class.

I'm using user controls as web parts in an asp.net application. I have skinned the webparts by adding .PartTitleStyle (etc) to my css. I'd now like to let the user select from a list in an editor part to choose the style for the web part.I'm able to change the title for the webpart, but can't seem to figure out how to change the css to use .PartTitleStyleCustom instead of the default, even trying to set the wp.BackColor seems to have no effect. Here is the code I have so far in the page load event of my user control:
