In an ASP.net MVC view, I have 3 partial views. And 3 Partial Views are having "submit" button.
I would like to display error / success message after click on Submit button based on some server side business logic.
I want handle exceptions in update panel control with c#.
View 1 RepliesI have created a partial view but I can`t figure out why i`m getting the following error message:
System.Web.HttpCompileException was unhandled by user code Message="c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\c2056548\c79d0820\App_Web_createdetails.ascx.2a617771.afok-sty.0.cs(150): error CS0030: Cannot convert
type 'ASP.views_project_createdetails_ascx' to 'System.Web.Mvc.ViewUserControl'" Source="System.Web" ErrorCode=-2147467259
What does that mean and how can I correct that?
I need to display an error message in the view when there's an error in rendering the partial view in that View.
How can i handle the exception while rendering partial view and display the error message in the view?
I have a page with an UpdatePanel with a UserControl in it. That UserControl contains a GridView with a nested UserControl that seems to disappear when the parent UserControl is rebound. I cannot for the life of me figure out why the child UserControl disappears. The code works beautifully on the first load, but any partial postback causes the "Pick" UserControl to disappear.
[Code]....
I have a linkbutton inside a updatepanel and when the update panel does a partial page rendering, the linkbutton disappears.
<asp:UpdatePanel ID="up" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList ID="drp" runat="server" AutoPostBack="true" CausesValidation="true">
<asp:ListItem Text="" Value="" />
<asp:ListItem Text="a" Value="a" />
<asp:ListItem Text="b" Value="b" />
<asp:ListItem Text="c" Value="c" />
</asp:DropDownList>
<asp:LinkButton ID="link" Text="abc" runat="server" />
</ContentTemplate>
I think that is because the link button is rendered using a script and that script is not run after the post back.
I have the following code:
public static PartialViewResult DateTime(this HtmlHelper helper)
{
return System.DateTime.Now.ToLongTimeString();
}
and now I want to return a Partial view from inside the DateTime method. But helper instance does not have any method for partial view.
I have a Controller set up for a certain View. This View contains 2 partial Views (ascx files). Each partial View has a Controller method that yields its DataModel. The containing View doesn't currently display any data, but just serves as a container for the 2 partial Views.
Here's the problem: The Index action of the containing View runs, but the Controller methods for the partial Views don't, so I get a null exception when the Model tries to render out the data that should be available. I'm using MVC 1.0, which is something of a bummer, since it seems that the next version is supposed to have something other than "RenderPartial" that will assist with this very issue. However, since I'm stuck for the moment with 1.0, can anyone give some advice on getting the Controller methods to run for the partial Views?
I removed the Trigger section the partial post back does not occur when I click add button on footertemplate of the gridview.
View 1 RepliesI have UserControl and within that control i have asp:ListView. Inside the ListView i have a asp:LinkButton. When i click on the LinkButton the control raises full postback, no matter if the UserControl is inside UpdatePanel or is not.

<asp:ListView ID="lvImages" runat="server" OnItemCommand="lvImages_ItemCommand">
<ItemTemplate>
<div>
<asp:Image runat="server" ID="imgImageThumb" ImageUrl='<%#Eval("Image") %>' GenerateEmptyAlternateText="true" />
<asp:LinkButton runat="server" ID="lbtnImageAdd" CommandName="Add" CommandArgument='<%#Container.DisplayIndex %>'
CausesValidation="false" Text="Add" />
</div>
<ItemTemplate>
</asp:ListView>

<ContentTemplate>
<cuc:UserControl ID="cucUserControl" runat=server/>

I am using an updatepanel and a grid is placed within the same.Now,I have a checkbox corresponding to each row of the grid.If I check it,say corresponding to one row and click a button(placed outside the panel), a popup will be opened which is a separate aspx page having its own functionality.

I got this an asp.net 3.5 page that and I have few tabs (telerik tabs control with pageview) and I have panel on the top of the page and inside that has a label control displaying error message if it's any.
At the moment, if I want to display this, at the end of the event clicked button for instance, I have to do a custom URL redirection class to itself passing error message and display the error. BUT the problem with this approach let say you are working on 4th tabs and you click save button inside this then you loose the state of series of control (what's is being choosed, selected, typed etc). The page refreshed and displayed at the first tab again.
I want to display the error and at the same time know the state is for every control on the 4th tabs and automatically goes to 4th tabs. BTW ... this validation is done through server level.
All the examples and websites i have looked at redirect a user to the error.aspx page when an error occurs. How do you just display a friendly error message on the page the user is viewing saying something like "Sorry unable to do whatever" I've tried using a try catch block on my class that executes a stored procedure and put another try catch on the controller, but this does not work and i still get the default error message (System.InvalidOperationException was unhandled by user code) My code is below:
[Code]....
So how can i just return ViewData["SqlError"] message in page.
I am trying to handle the unhandled exceptions in my project.I tried with this following code in my web.config filebut it is not at all redirecting to an error page which i have created instead of that it is throwing an exception in my code itselef. How to print the error description over therein my custom error page.
---------------------------------------------------------------------------------------------------
<sys.web>......<customErrors mode="On" defaultRedirect="~/Error.aspx"></customErrors>...</sys.web>
---------------------------------------------------------------------------------------------------
And even i tried in Global.asax page in Application_Error() method like below
Exception ex = Server.GetLastError();Response.Redirect("~/Error.aspx?errmsg="+ex.message);Server.ClearError();
And in my Error.aspx.cs page i have placed a label and i have written code like this
protected void Page_Load(object sender, EventArgs e) {
Label1.Text=Request["errmsg"];
}
But it is not getting redirected my error page and not displaying anything on it.
When the user clicks the submit button on a form I want to return a success / failure message to the user and i'm wondering what the best way to send the message back to the user is.
For example on a login form if the user enters an incorrect password i'd want the view to reload with a message telling them that login failed. Or on an update form the original view they had would show up with a message saying update was successful.
My idea is to have a few partial views or HTML helpers that look for a ViewBag property like "ErrorMessage" or "SuccessMessage" and conditionally show themselves when these properties have a value. These components could be added to the _Layout or manually each form where they are required.
Edit
I have since found out that the ValidationSummary method takes a parameter of whether to exclude property errors which means you can use it to show when login / registration has failed. But there seems to be a bug where the validation summary is still generated even if there are no errors.
I have a master page with a partial view. I want the partial view to display only when viewing a specific page/action. Is there any conditional I can wrap around the partial view that checks for the page/action I'm viewing?
