MVC :: Setting Attributes Conditionally In Html.BeginForm
May 6, 2010I have a form that should have all html elements disabled unless a user id is present, indicating that a user has been loaded for editing. I've done this, which works:
[Code]....
This works, and all is good. I couldn't set an if statement up to control creation of the entire Html.BeginForm, which was a bit of a pain. When I tried, the View thought I was creating 2 form begin tags with only one end tag, even though it was inside a conditional statement. Whatever. The problem I now have is that I need to assign an id for the form to work with a validation plugin. I can't add the id = "someID" inside of the condition, because it won't be available when the user id is present, which completely defeats the purpose. I can't move the ternary condition to inside of the 'new' statement - I tried. I thought this would work:
[Code]....
But no dice. I get the following error: Type of conditional expression cannot be determined because there is no implicit conversion between 'AnonymousType#1' and 'AnonymousType#2'. What? Seriously? I'm not trying to convert anything. I'm either assigning a new html attributes section with one set of values or another set of values. Since I can't perform the conditional logic inside of the 'new' statement, I have to recreate the entire 'new' statement after the condition is tested, but this still doesn't work, as I get the aforementioned error. As a short-term fix, I'm going to just render an actual html form tag with the required data, but I'd like to know why it is that code executed/rendered within conditional statements doesn't understand that both true and false results aren't running, and also how to fix this issue while still using the Html.BeginForm helper.

Moving The Javascript Code To Design View Is Not Working. Only Code-behind Attributes.Add ("onclick" Works. Puzzled
Jul 15, 2010I wanted to disable a button after it is clicked and at the same time fire the post back event to generate a report. My first set of code did not work because soon after the button is disabled the page won't submit/post back. here's the first set of code which was not implemented. the onclientclick calls a javascript function which has these lines
document.getElementById('btnGenerateReport').disabled=true;
GetPostBackEventReference(btnGenerateReport,'');
since it was not posting back,i tried the following on page_load code behind
btnGenerateReport.Attributes.Add("onclick", "this.disabled=true;" + ClientScript.GetPostBackEventReference(btnGenerateReport, ""))
that worked well. but I tried to copy the javascript that got generated and pasted directly on design view
onclick="this.disabled=true;__doPostBack('btnDownloadClientsWithConviction','');"
its not working from client side alone after I disable the code behind attributes.add
but when I check the view source the 2 pages are the samewhy am I not able to move the code from code-behind to design view?

C# - How To Dynamically Retrieve All The Possible Attributes (variable Attributes) Values Of One Of The Xml Node
Aug 10, 2010I am using the following XML structure
<SERVERS>
<SERVER NAME="A1" ID="1"></SERVER>
<SERVER NAME="A2"></SERVER>
<SERVER NAME="A3" ID="3" Parent="XYZ"></SERVER>
<SERVER NAME="A4" ID="4"></SERVER>
<SERVER NAME="A5" Parent="abc" value="10"></SERVER>
<SERVER NAME="A6"></SERVER>
</SERVERS>
I am accessing this xml file by using LINQ to XML in asp.net by using C#. I am able to access all the attributes of an XML node by explicitly specifying the name of the attribute. I want to write query on this xml file which reads all the attribute values of the xml node (In our example the node is SERVER) dynamically means I want to write the query which can read the read the value of the attribute Name & ID from first node, only name from second row, Name, ID & Parent from the third row , Name & ID from the fourth row, Name, Parent & Value from the fifth row & only Name from the sixth row without modifying the existing code every time. Once I add one of the attribute ( for example if I add the attribute ID in the sixth row ) in the above xml file then I dont need to modify my LINQ to XML query. My query should dynamically fetch the total number of attributes & display their values. Is their any way to do this ?

Setting HtmlInputRadioButton Name In GridView From Code Behind
Jan 6, 2011On 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.

Web Forms :: Setting DataNavigateUrlFields In Code?
Jun 15, 2010I'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?

VS 2010 / Setting Image Button URL In Code Behind?
Sep 16, 2014I 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(' ')

Web Forms :: Setting Menu Selected Item From Code Behind?
Nov 10, 2010I 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?
Security :: How To Deny User With C# Code Instead Of Setting Web.config
Oct 16, 2010I 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?
Forms Data Controls :: Setting EmptyDataText From Code Behind
Jun 10, 2010I 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.

AJAX :: Setting Focus On ModalPoupExtender From Code Behind Show() Method?
Feb 22, 2011I have figured out a method for displaying a modal popup using the ACT ModalPopupExtender from the server side.This is really important because there is a fair amount of server side initialization that I require prior to showing the dialog.
Basically, I assign a dummybutton as the TargetControlID. Then I define a link button such that when clicked it fires an OnClick event. The handler then does whatever initialization is necessary and uses the show() method of the ModalPopupExtender. This is not rocket science. However, what appears to be rocket science is getting a control within the MPE to get the cursor focus. The problem as I see it is that because I am manually showing the dialog, the JS add_shown function never fires. Of course the add_shown function is attached through JS by using the behavior ID of the MPE. It appears to be the standard way to set focus within a MPE dialog. It appears to only work if the targetcontrolid is a real button that shows the MPE dialog when clicked.
Is it possible to set the focus within a MPE dialog when you are programatically showing the dialog and not attaching a real button press event to the MPE Target Control ID? Obviously the Page.SetFocus or Control.Focus() do not work either before or after the modal dialog is shown:
protected void SignIn_Click(object sender, EventArgs e)
{
Session["InTimeOut"] = true;
Session["logintries"] = 0;
SI_user_login_id.Focus(); /// ---> This does not set the focus either before or after the show method
this.ModalSignOn.Show();
}
