In my immediate window I get the following:
?DirectCast(Me.FindControl("txtFName"), TextBox).Text.ToString().Trim()
Referenced object has a value of 'Nothing'.
?txtFName.Text
"Lisa"
So .. if I take out the DirectCast syntax, the value is passed but with DirectCast I get the Referenced Object has a value of nothing .. why and do I even need DirectCast here?
I am making some application in asp.net 1.1 in that I am displaying data in datagrid from database. In data grid first column is of check box and radio button and in the last column we have text box now thing is that when i click on check box crosponding textbox we fill some figure and at the end we press calculate button to get total. After getting total we have to press continue button to go next step
But suppose if some body remove that check the we should press calculate button or chnage some figure in the text box then we should press calculate button again to recalculate. for that i kept autopost back on check box oncheckedchanged event and text box ontextchanged event and hide continue button so user will click calcutae button abd then continue button will re-apper
Problem it that it taking too much refresh and taking long time. So was lloking for some ajax method to use in my application.
What the difference between the what is byval sender as object and DirectCast(LoginView1.FindControl("NewAssignTL"), DropDownList)
both of them works. can anybody enlighten me with the knowledge.

The following CLR syntax works fine in my aspx page:
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="Website.MyBasePage`1[HomePageViewModel]" %>
But this C# syntax does not:
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="Website.MyBasePage<HomePageViewModel>" %>
Note, I am not using ASP.NET MVC, but this works fine if using System.Web.Mvc.ViewPage<> from ASP.NET MVC.
My MyBasePage looks like this:
public class MyBasePage<TModel> : Page where TModel : class {
public TModel Model
{
get { return (TModel)HttpContext.Current.Items["model"]; }
}
}
For reporting we used report RDLCs and displayed using an ASPX form. We implemented using the route as shown below. This resulted in forcing us to use the page route below and also to use the hyperlink instead of the normal Action Link. The question is how do we convert the asp:hyperlink ASPX syntax to Razor syntax.
//Custom route for reports routes.MapPageRoute( "ReportRoute", // Route name "Reports/{reportname}", // URL "~/Reports/{reportname}.aspx" // File );
<li><asp:HyperLink ID="hypReport" runat="server" NavigateUrl="<%$RouteUrl:routename=ReportRoute,reportname=StaffRpt%>">Staff Report</asp:HyperLink></li>
I am working with a sql server database with about 50 stored procedures. The database and stored procedureswere not created by me. The stored procedures all begin with a number in their name.
Example: 17P_Comsetter
The problem I am having is that if I try and execute the stored procedure at the command line in Query Analyzer,the query analyzer appears not to like that the stored procedure begins with a number. For example:
If I try an run the stored procedure as follows:
EXEC 17P_Comsetter
Then I get the following error message:
Msg 102, ..... Incorrect Syntax near '17'
I am using SQL server 2005. Does anyone know why I am getting this error message?
DataRow[] filterRows = ds.Tables[0].Select("Running Status= case State when 'True' then 'Running' When 'False' Then 'Stoped' end Where Active='1' and State='1'");
this is not working showing syntax error syntax error:operand is missing

View 2 RepliesMy gridview has hyperlink field which will redirect to another page when clicked. Is there any way to hide the values from being shown in the URL? I do not wish to have encrypted values as well.

Any way to show it as
http://localhost:3042/Customer/CustomerDetails.aspx only?
I am really sorry for this, but this is such a bizarre situation I don't know where to turn. I have a stored procedure that takes four parameters (two dates, a positionID, a userID). The SQLDataSource is very generic:
[Code]....
and I set the parameters via this code:
[Code]....
When this executes, no matter what the value of PositionID, it acts as if the PositionID is zero. Now, if I remove PositionID variable and add the number:
[Code]....
All is well. Also, when I look at the parameter in the immediate window, it appears to be correct:
[Code]....
Dim begin As String = Convert.ToString(Master.FindControl("txtBegindatum"))

System.Web.UI.WebControls.TextBox in txtStart and txtEind
Is there a way of checking validation on the fly as the user inputs data and then when all validation is passed - change the submit button to green colour?
View 1 RepliesI have a table with 100 cells in it (10x10)
In each cell there is a checkbox. On page load, each checkbox is checked depending on records 0-99 from a database. This works fine.
However, I want to be able to update those 100 records in the database by checking or unchecking the checkboxes.
The update process works ok as I have debugged it, but the problem seems to be that if I check a checkbox, that value (true or false) doesn't get passed to the event handler.
This is the button click event handler that I'm running right now to see if the value is being recognised:
[Code]....
If I tick checkbox zero and click the button, it still comes up as false. What I want to happen is that the DB is updated and when the page loads, the checkboxes are repopulated with the new values from the database.
In ASP.Net, is anyone aware of a way to bypass Forms Authentication if a specific query string parameter is passed in?
Such as:
mydomain.com/myprotectedpage.aspx
...I would like to be protected by Forms Authentication (and so, redirected to login page)
mydomain.com/myprotectedpage.aspx?myBypassParameter=me
...I would like the page to render as normal
Can't say I'm new to this, but I just can't see what I'm doing wrong. Can some one please take a look at this and point out why is my Edit event from the DataList not exporting the index value that is needed to populate a FormView? Below is my reduced code.

Is there a way to set the RequiredFieldValidator to use display:none (or something equivalent) unless there is an error? The problem that I'm having is that the error text in the validator is taking up space even when there is no error on the page.
View 1 RepliesI have a webform that uploads data to a SQL Server 2005 DB. When run it on my local machine it works like a charm and is very fast. When I move my web form to my Hosting company's web server and try to upload to my DB it takes a very long time (5 min plus to upload 10MB) or it times out or both. My web hosting company can't seem to fix this.
Has anyone had a similar problem or any clue what might be happening?
I have a web page and i have one user control and one buttone on page...
I am displaying some data on that page.
But problem is that buttong is loading after almost 30 to 40 seconds event after whole data displayed and progress bar of ie is also does not complete
what i have is a web form with a number of input fields . But some of the fields have the magnifying glass search image so that the user can click and up pops some results to pick from.
So what i have is like the following
Item Code {image here}
Supplier Name
Supplier Code {image here}
and so on ..
so what i want to do is create a user control that i can call from any web page that has the image on it and the name of the label can be passed .
So the control would be a probably label with an image to the right of it and in the markup when the it is called , a label name is passed in order to display it on the page .. also label id and a click event on the magnifying glass because each label might have a different id and the click event on the magnifying glass for each is different .
eg: <uc1: id="SearchControl" Text="SupplierCode" runat="server">
and this would output
Supplier Code {image here}
