Mar 17, 2011
I have created a gridview which adds a remove button through item template. I wish to know how do u remove the row from grid view dynamically depending upon the button he clicks ?
protected void RemoveBtn_OnClick(object sender, EventArgs e)
{
Button clickedButton = sender as Button;
GridViewRow row = (GridViewRow)clickedButton.Parent.Parent;
int rowID = Convert.ToInt16(row.RowIndex);
GridView1.DeleteRow(rowID);
}

I need to have a siteMapeNode for a menu control to only show up during development.
The following node would be in the web.sitemap file.
[Code]....
I can either put this node in my web.sitemap file and remove it in release builds.
Or Add the node in debug builds.
Probably done in PreInit or Page_load events.

I've been at this same question in different forms now for a while (see e.g. Entity Framework and MVC 3: The relationship could not be changed because one or more of the foreign-key properties is non-nullable. ), and it's still bugging me, so I thought I'd put it a little more generically:
You have an entity object (using Entity Framework), say User. The User has some simple properties such as FirstName, LastName, etc. But it also has some object property lists, take the proverbial example Emails, to make this simple. Email is often designed as a list of objects so that you can add to that object properties like Address and Type (Home, Work, etc). I'm using this as an example to keep it generic, but it could be anything, the point is, you want the user to be able to add an arbitrary number of these items. You should also be able to delete items (old address, or whatever).
Now, in a normal web page you would expect to be able to add these items in the same View. But MVC as it seems designed only makes it easy to do this if you call up an entirely new View just to add the address. (In the template for an Index View you get the "Create New" link e.g.).
I've come across a couple of examples that do something close to what I mean here:
[URL]
and
[URL]
The problem is, although the sample projects on these sites work fine, with mock model objects, and simply lists (not an object with a child list), it's a different thing if you actually want to do something with the posted information - in my case save to database through the Entity Framework model. To adapt these cases to that, all of a sudden I'm in a maze of intricate and definitely not DRY code... Juggling objects with AutoMapper and whatnot, and the Entity Framework won't let you save and so on (see above link if you're interested in the details).
What I want to get at is, is it really possible that this is such an uncommon thing to want to do? Update a child collection in the same View as the parent object (such as the email addresses in this case)? It seems to me it can't be uncommon at all, and there must be a standard way of handling this sort of scenario, and I'm just missing it (and no one here so far has been able to point me to a straighforward solution, perhaps because I made it too abstract with my own application examples).

sometimes we need to use the asp image control so we can generate empty alt tags (visual studio 2005 does not render any attributes set
to an empty string). I know how to do this and also how to remove the border style that is automatically added
(http://blog.josh420.com/archives/2007/10/aspnet-image-control-border-width-inline-style.aspx).
We implemented this 6 months ago, however, only today have I discovered that it does not work when images are created dynamically.The first implementation was for asp images that have been set up within an aspx page:
-<asp:image runat="server" id="imgMast1" GenerateEmptyAlternateText="True" alternatetext="" imageurl="" />
The above works-no border style is rendered and the imageurl is populated in code.I have other pages where I'm building up sections dynamically using C# code, such as:-
System.Web.UI.WebControls.Image featureImage = new
System.Web.UI.WebControls.Image();
featureImage.GenerateEmptyAlternateText = true;
featureImage.ImageUrl = imageSrc;
divImage1.Controls.Add(featureImage);
divImageFeature.Controls.Add(divImage1);
When creating controls dynamically like this, the solution describe above does not remove the border style.

I want to create a mailto anchor tag at runtime. Is this possible? I've tried this:
[Code]....
Neither of these worked. I tried adding the "mailto:" in front of the {0}, but this just became part of the perceived URL. I read a post online about using data attributes to add the value as a property of a class, but I can't do that, as I'm stuck using .NET 3.5 for this project. I honestly didn't think this was going to be such a big deal. I just want to populate the email address of the anchor tag with a variable value.

Newbie in using AJAX . Programming in C# and using SQL as a database. Here is my scenario. User selects a project and I want to display the subprojects related to that project. Here is the query I use to retrieve subprojects.
"SELECT SubProjectName,StartDate,Description FROM SubProject WHERE ProjectName'"+ddlProjectName.text+"';
Currently I store the results of the query in a Dataset. I want to get the SubProjectName in the Header of the Accordion and StartDate and Description values to the text box for each accordion. ( This is what I need to do in each accordian for each subproject)
<asp:AccordionPane ID="AccordionPane2" runat="server">
<Header>
<a href="" onclick="return false;" class="accordionLink">SubProject 1</a>
</Header>
<Content>
<table width="100%" cellpadding="0" cellspacing="0">
<tr>
<td class="td_left" colspan="2">
<asp:Label ID="Label1" runat="server" Text="Start Date"></asp:Label>
</td>
<td class="td_left" colspan="2">
<asp:TextBox ID="StartDate" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td class="td_left" colspan="2">
<asp:Label ID="Label2" runat="server" Text="Description"></asp:Label>
</td>
<td class="td_left" colspan="2">
<asp:TextBox ID="txtDecription" runat="server"></asp:TextBox>
</td>
</tr>
</table>
</Content>
</asp:AccordionPane>
How can I do this? Some code example would be great on how to creat the accordinas ,text boxes dynamically and fill the values.

I have a requirement whereby one or more image buttons need to be created in a user control at runtime. The number of buttons is determined from a database where a user can add one or more rows that contain an image for each button, so if a user adds 3 images to a table, 3 image buttons are created. Ive used this code but I get an error at runtime
The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.
[Code]....
this is the usercontrol aspx
[Code]....
I basically want one or more buttons to render within the div in the usercontrol. Ive only got the code written for one button at the moment while I test the rendering, eventually they will be rendered in a loop of records taken from a database. Whats the best way to do this ?

I'm building an application that will be used by a number of different schools who want completely separate databases so I've decided to have multiple connection strings and membership/role providers in my web.config file. In my code, I'm trying to set which connection string and provider to use at runtime for the correct database according to the logged in user.
I'm coming into a lot of bits in my code that previously worked fine, that now don't. For example, I used to use:
[Code]....
But now that I've changed it to this, it doesn't work anymore:
[Code]....
The compiler tells me that AddUserToRole is not a member of 'r'. I've had similar problems not just with Roles but Membership too, like with calling CreateUser.
I'd still like to be able to use all these methods that I was using before which are extremely handy. I just want to be able to set the membership/role provider at runtime rather than use the default one. Am I doing something wrong? Is there a simpler way to go about this?

The following link describes the relationships between a Partial View and its parent in terms of ViewData: [URL] In relation to the text: "A partial view enables you to define a view that will be rendered inside a parent view. Partial views are implemented as ASP.NET user controls (.ascx).
When a partial view is instantiated, it gets its own copy of the ViewDataDictionary object that is available to the parent view. The partial view therefore has access to the data of the parent view. However, if the partial view updates the data, those updates affect only the partial view's ViewData object. The parent view's data is not changed"
how the parent view can make use of the new data added or existing data changed and updated, by the partial views? My question is around how to load partial views dynamically at runtime using Html.RenderPartial(...) whilst having one version of the data used and updated by the parent view and it's children.
