i am trying to create a datatable entering the columns that i create before, but i have a problem, the dataColumn doesn't have the required data, there is a AllowDbNull but it doesn't work.
Then i would like to add other restrctions like MinLegth.
Does anybody know how to do this?
I am getting an error in my web.config which says missing required attribute 'name' and the following excerpt is displayed:
Code:
20: <handlers>
21: <add path="c1chartimage.aspx" verb="*" type="C1.Web.C1WebChart.ImageHttpHandler,C1.Web.C1WebChart.2" />
22: </handlers>
I am migrating from IIS6 to IIS7, and IIS6 was fine with this. I already made one change (system.web to system.webServer) and I don't know what's wrong with it now.
We're trying to get a conditional attribute to work, case in point, there's a boolean (checkbox) that if checked, its related text is required. So, ideally we'd have something like ...
public bool Provision { get; set; }
[ConditionalRequirement(IsNeededWhenTrue = Provision)]
public string ProvisionText { get; set; }
Is this even possible?
Alternate idea (not as elegant?)
public bool Provision2 { get; set; }
[PropertyRequired(RequiredBooleanPropertyName = "Provision2")]
public string Provision2Text { get; set; }
I'd hate to use the magic string method .
1)we are calling them as client side controls,then what is the need for runat server attribute?
2)<asp:Button ID="Button1" runat="server" Text="Button" />
<asp:ConfirmButtonExtender ID="Button1_ConfirmButtonExtender" runat="server"
ConfirmText="Really?" Enabled="True" TargetControlID="Button1">
</asp:ConfirmButtonExtender>
when i execute the above code,i observed that in status bar message as "connecting to localhost",if they are client side controls what is the need of going to local server,why it is happening?

This takes care of validation... However the messages are always in the default language. Meaning that the setting of the culture of my thread is occuring too late (I'm currently setting it in my base controller 'OnActionExecuting'). Where could I patch in to change the culture accordingly before validation takes place?
I can't see what I've missed
Dim strSQL As String = _

View 2 RepliesI am building a page that displays a product's details, with the information being called from an MSSQL database.I would like to be able to have a variable number of features listed for each product, so for example, Product A has a list of 3 features, Product B has a list of 7 features, Product C has 2 features listed etc.I would like to avoid having a lot of NULLS in my database, and would prefer not to restrict the number of possible features listed.Is there a common way to tackle this problem? Is it simply a case of setting up a table just to store features?

When a user creates an account for my web application using the create user wizard additional steps have been added to take more details and store them in another table. Now this tables primary key is set to uniqueidentifier, is it possible to have that unique identifier automatically generated when the query is run to insert a new row for a new user?

View 1 RepliesI am writing an app that has a bit of process flow to it. On the save of a record, I need to check some fields to make sure they are not null. If they are not null, I will update a 'SectionComplete' field to true.
The thing is, I would like to store my fields in the web.config. So, I would like to have a string in the appsettings section that has a list of field names that are required. Then in my method, I would call these fields out and check each one for the specific record id, and then update the database.
I would like to do this in the web.config so we could add/remove columns without having to redeploy.
For example: my required fields are name, id, and phone. For section one to be labeled complete, all of these fields would need to be not null.
web.config would have this entry:
<add key="Stage1Fields" value="name, id, phone"/>
When I generate code using T4 templates in Visual Studio 2010, I get the following error for each of my asp controls when I try to compile:
Control "ddState" is missing required attribute "showat".
I have never gotten this error in previous versions of .NET. Further, I don't get this error when I manually construct my pages either by dragging/dropping, nor do I get it when I type out the control text myself. When I generate code, I have to manually add showat="client" to my tag for the compiler to be happy. It was my understanding that I never had to explicitly specify this tag. The following:
<asp:dropdownlist id="ddState" runat="server" showat="client" />
solves the problem. Why do I have to add this to generated code but not other times?(It's a VS-2010 webforms project, using VB, in case that makes a difference.)
<asp:GridView ID="GridView1" runat="server">

I'm getting this error on the above markup: Message 1 Validation (ASP.Net): Attribute 'onchange' is not a valid attribute of element 'TextBox'.

What attribute would I use for Css with ListItem?

This query works fine and returns 1 record from type int:

I have a DataTable that I am creating and binding to a GridView. Currently the headers do not have any spaces and it makes it hard to read. I want to space them out but I'm having a minor issue. What I am trying to accomplish :
Dim dc As Data.DataColumn
dc = New Data.DataColumn("Updated Date", System.Type.GetType("System.String"))
dt.Columns.Add(dc)
What I currently have :
Dim dc As Data.DataColumn
dc = New Data.DataColumn("UpdatedDate", System.Type.GetType("System.String"))
dt.Columns.Add(dc)
I know that I can set the HeaderText in the columns declaration like below, but I won't know how any columns I am going to have. And would rather the columns be generated automatically.
<Columns>
<asp:BoundField DataField="UpdatedDate" HeaderText="Updated Date" />
</Columns>
I'm using a DataGrid with edit functionalities in my project. It's handy, compared to having to edit its source data manually, but sadly, that means that I'll have to deal with validating user input a bit more.
And my problem is basically just that. When I set my DataGrid to EDIT mode, modify the values and then set it to UPDATE, what is the best way to check if a value that I've entered is, in fact, compatible with the corresponding column's data type?
i.e. (simple example)
// assuming
DataTable dt = new DataTable();
dt.Columns.Add("aa",typeof(System.Int32));
DataGrid dg = new DataGrid();

how do i copy required row in dataset to a new dataset. i have bind a xml into a dataset and i need to display say row 3 to 5 only so i do a for loop but i have encounter problem when trying to copy the rows to a new dataset.
do i have to write the xml to datatable and bind it to dataset and from there copy over ?
How do I go about adding a ButtonColumn to a DataTable.
I am basically using a DataTable as the DataSource of a DataGrid and need to add a ButtonColumn to the DataTable so that when I DataBind it to the DataGrid it all works.
Although when I try
dt.Columns.Add(buttonColumn)
This is not allowed. It has to be a basic DataColumn.
In may page, i am assigning DataTable to a GridView as follows:
GridView1.DataSource = GetDataTable();
GridView1.DataBind();
Now,the definition of GetDataTable is as follows:
DataTable abcd = new DataTable();
DataRow dr;
abcd.Columns.Add(new DataColumn("Column1"));
abcd.Columns.Add(new DataCoumn("Column2"));
dr=abcd.NewRow();
dr["Column1"]="My Name";
dr["Column2"]="<p>My Address Line1</p><p>My Address Line2</p>";
abcd.AddRow(dr);
return(abcd);
dont bother about code syntax or functions, I just dont have actual code right now.Its on the similar lines...
My question is, when i see GridView, It prints <p></p> in Column2 as it is.. it doesnt consider those tags as HTML tags...
I want DataColumn to consider those tags as HTML, so that my address gets printed on two different lines but in same column.
If you guys have any other way to work around... just the thing is that I must assign DataTable to GridView.
I'm trying to set the datatype of my DataColumn like this:
[Code]....
But I get an error that says Name cannot begin with '>' character.
How can I add an array of string to data column of a an empty data table in asp.net?
