I have a asp radiobutton on my page and when I display the page it appears that the border for he radiobutton is 50px and the text for the radiobutton is shoved down to the next line. I have the markup for the radiobutton below. When I use a standard HTML radiobutton it appears correctly on the page. See markup below:

I want a separate config file (not app.config) that stores style for various controls in my web application. For example i want to specify the CSS file that modifies all instances of GridView in the website. what is best practice?
View 2 Repliesi added this entry in my web.config file
pages
masterPageFile="~/default.master"
so that all my content pages (.aspx) in my application could use default.master as their master page,
i read we do this so that we don't have to mention the MasterPageFile="~/default.master" everytime in all the .aspx content pages, but , my query is whenever i add a new .aspx page in my website from VS 2010, it dosen't automatically add MasterPageFile="~/default.master" to the Page header, am i missing something.
ASP.net radiobutton change event writes the new selection to an XML file and that needs to be shown on the page but does not show the changes on the page since the page load occur before the event fires. give some insight how to resolve this.

I am new to ASP.NET development and I am running into an issue using master/content pages. I have a master file that basically defines all of the layout for my site. The only thing that the content pages are supposed to display is some very basic text/images/html, made available by one ContentPlaceHolder control in the master file.
My problem is in the display. When I view the content page, none of the layout that should be inherited from the master page is displayed -- I end up with just a 'blank' page. What seems odd, is that if I look at the Design View in VS 2005, the content page appears to show the layout that is defined in the master. Here is a sample of the source for the master and one of the content pages...
Master Page: content_pages.master

I have an application in which a user can choose from different (learning)groups. User has only access to registered groups. When the user enters the site, he can choose (in a dropdown) which group he wants to see, so the complete site filters content related to that group. So every controller needs to access this global "group" object.What is the best way to do this in ASP.NET MVC? I've thought about a BaseController or ActionFilters. Is there any other best practice?I've build a WebForms application and there I used a BasePage so that any other page has access to the group.

I have a ReportViewer (ver 10) that is rendering far wider than the box it's meant to display in. The problem is that the Parameters area is appearing much wider than the actual report area. If I put an "overflow: auto" in the div that contains the ReportViewer control, then I get a horizontal scrollbar at the bottom, but then in order to click the "View Report" button I have to scroll way over, thus moving the entire report.
Ideally I would like the Parameters area to stay stationary, but a horizontal scrollbar to appear on the report area so that it can be scrolled if necessary. What is the best way to go about doing this?
Here's what my control setup looks like now:
<div class="reportingFrame" style="text-align: center; width: 100%; overflow: auto">
<sam:ReportViewer ID="UiReportViewer" runat="server"
AsyncRendering="False"
ProcessingMode="Remote"
ShowExportControls="False"
ShowPrintButton="False"
ShowPromptAreaButton="False"
ShowRefreshButton="False"
SizeToReportContent="True"
Width="100%" />
</div>
Currently I'm looking at some jQuery tricks to reformat the output from the ReportViewer control into a better system
I have a repeater in which there is a Row which brings a value of Salary from a table. And there is a condition:
1)When user adds the salary value in a textbox, there are two radio buttons, YES and NO,
I want, whenever user selects the yes option, the salary value should be displayed in the repeater.
see the code for the Repeater and Textbox, Radiobuttons:-
Repeater code:-
<asp:Repeater ID="rep_Jobs" runat="server">
<ItemTemplate>
<h3 class="parag"><%# Eval("Position") %> - <%#Eval("Location") %></h3>
<div>

Note: The textbox of salary and Repeater is two different page. What should I do to show in repeater when the radiobutton is selected YES.

What is the recommended or usual way an ASP.net web application(in C# language) can store/access values that are needed accross the various pages in a website. For example a basic company website might need the company's name and other related information available to multiple pages. Where do I declare these variables/values and how do I access them. Coming from c++ application programming I would usually store such data in a Singleton class object.

How to do wide search and export the records to excel file ? im quite new in asp.net .
I have a series of GridViews in a Tab Panel - databound to a generic List of Business Objects. The columns in the Gridview are all similar to the following:
<asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName">
<ItemTemplate>
<asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList ID="ddlCompany" runat="server"></asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>
The GridView generates the "Edit" link at the beginning of the row, all the events fire ok. The problem is that the data is getting long. When in 'display mode', it's fine because the GridView control is smart enough to break some text into multiple lines (in particular Project, Title and Worker names can get pretty long). The problem come in editing mode. Drop-down lists DON'T break entries into multiple lines (for obvious reasons). Going into Edit ode on a row in the Gridview can make the Griview expand horizontally to twice the screen size (blowing through the width limits in the Master page and CSS but that's only a related problem).
What I need is something like the ModalPopup - but trying to tie it to an ID in an EditItemTemplate gives me errors when the page renders (because the 'ddlXXXX' doesn't exist at the time). In addition I don't know how to dynamically populate the panel so that I can get a response from it (like the ID of the Company they selected)
.
I'm also trying to avoid javascript and would like this to be a 'pure' aspx/code-behind solution (for simplicity's sake among others).
All the examples I find are of Modal Popups with the panels pre-defined. Even if it (the popup panel) were something like a list of checkboxes, it could be databound to the SortedList I have ready to go and an OK/Cancel button combination to accept or ignore things. I'm just not sure of what goes where.
EDIT: Final solution looks as follows:
<asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName">
<ItemTemplate>
<asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:LinkButton ID="lnkCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:LinkButton>
<asp:Panel ID="pnlCompany" runat="server" style="display:none">
<div>
<asp:DropDownList ID="ddlCompany" runat="server" ></asp:DropDownList>
<br/>
<asp:ImageButton ID="btnOKCo" runat="server" ImageUrl="~/Images/greencheck.gif" OnCommand="PopupButton_Command" CommandName="SelectCO" />
<asp:ImageButton ID="btnCxlCo" runat="server" ImageUrl="~/Images/RedX.gif" />
</div>
</asp:Panel>
<cc1:ModalPopupExtender ID="mpeCompany" runat="server"
TargetControlID="lnkCompany" PopupControlID="pnlCompany"
BackgroundCssClass="modalBackground" CancelControlID="btnCxlCo"
DropShadow="true" PopupDragHandleControlID="pnlCompany" />
</EditItemTemplate>
</asp:TemplateField>
And in the code-behind, lstIDLabor is the generic List of data lines (of which Company is one of the properties that is also a business object) that is bound to the GridView:
Sub PopupButton_Command(ByVal sender As Object, ByVal e As CommandEventArgs)
Dim intRow As Integer
Dim intVal As Integer
RestoreFromSessionVariables()
Select Case e.CommandName
Case "SelectCO"
intRow = grdIDCostLabor.EditIndex
Dim ddlCo As DropDownList = CType(grdIDCost.Rows(intRow).FindControl("ddlCompany"), DropDownList)
intVal = ddlCo.SelectedValue
lstIDLabor(intRow).CompanyID = intVal
lstIDLabor(intRow).Company = Company.Read(intVal)
Case Else
'
End Select
MakeSessionVariables()
BindGrids()
End Sub

View 1 RepliesFor certain parts of the site the allow inserting and updating of data we have some try / catch logic in place.. Now we would like to display a custom error page explaining what didnt happen. Instead of just a generic message that says error occurred. Here is 1 error that is generated due to Primary Key constraints, we woudl like to redirect them to our error.aspx page which is already setup and configured in the web.config but within that page display a more user friendly detail message of why they got the error. In the example below, we may want to say, "There was an error with the "Access Insert" please make sure that the values you entered on the previous page are unique" thats just an example, but gives an idea of what we are trying to do.
