SQL Server :: Assign Result Of Count Stored Procedure To C# Variable?

Aug 7, 2010

I have an aggregate stored procedure (named sp2) that returns a count of records meeting a certain criteria ASrecCount. I am using a DAL per the ASP.NET tutorial and have created a Table Adapter (named
sp2TableAdapter) with GetData and Fill methods. I have a button on an ASP.NET page that launches an event handler. In the button's event handler, I have this line: sp2TableAdapter sp2 = new sp2TableAdapter();
What works so far:

This code will bind the value of sp2 to a data control:

sp2TableAdapter sp2 = new sp2TableAdapter();
DropDownList1.DataSource = sp2.GetData();
DropDownList1.DataValueField = "recCount ";
DropDownList.DataTextField = "recCount";

When running this page and clicking the button, the numeric value of recCount returned from sp2 is bound to the DropDownList control and 1 row is poplated with the recCount value (in my case 1451).

In the event handler, I do not want to bind the value of recCount to a control, but want to to use it in some logic as an integer. What is the C# code that will do this? (In place of the DropDownList control lines above)

How To Assign DataRow To Variable In Grid

May 10, 2013

Right now I am using a grid control from ComponentOne which I have to stay with. When I click an link in the row which fires a grid_ItemCommand event one of the parameters passed is e As C1.Web.C1WebGrid.C1CommandEventArgs. I want to change it where I am selecting a row with a checkbox in a column and then click a button to process the row selected. So I need to get the value it is putting in e and pass that which is used in another sub.

Here is how e is assigned to "row" as DataRow.

Private Sub grid_ItemCommand(ByVal sender As Object, ByVal e As C1.Web.C1WebGrid.C1CommandEventArgs) Handles grid.ItemCommand
Select Case e.CommandName
Case "Renew" ' Renew barcode
Dim row As DataRow = CType(e.Item.DataItem, DataRowView).Row

Web Forms :: Can't Assign Values To Variable In User Control

Jun 17, 2010

I have a simple user control which toggles between the visibility of a few images depending on the UserId. When the page is loaded for the first time, the userID is being assigned correctly (I'm debugging). However, there are two other buttons on the page for filtering the type of users, they are perform their functionality via Ajax (not the toolkit, but the normal javascript ajax) When one of these buttons are clicked, the user control cant get the userid, it always comes up as Zero. Oh, btw, the usercontrol is in a DataRepeater, so it occurs for each of the user.. all the time.. or thats the Idea. I have several other pages like this, (none of them have ajax) and the user control has no problems whatsoever.

My User control code:


And the Data Repeater is something like this:


Here, Immediately after the userControl <ucAB:....> line, I am printing the userid just to see if its valid (by <%# Eval("UserId") %> and the user id's are valid too. I dont understand why the User Control cant pick it up on ajax postback?

ADO.NET :: Assign Null Value To Variable That Is Not Variant Data Type

I would like to enquire about a seemingly basic problem that i am struggeling with. I have been trying to add information to an access database and as i am inserting this information I get the error message stating that I tried to assign the Null value to a variable that is not a Variant type. I was thinking that it could have something to do with the primary key being set to automatic number but this also does not seem the problem.

Forms Data Controls :: Assign Datalist Value To Variable

Jul 8, 2010

I have a Datalist and when a button is clicked I would like to send the values of the fields to a new page to fill some text boxes. What is the best way to do this. I had thought that since the DataList had itemtemplates that were labels I could reference them like regular labels ( str = Label1.text ). That isn't working. I was just going to send the values through a query string. Which I have an example of that, unless there is a better way.

How To Assign A Control Property Value From A Global Variable In Page Code

Aug 31, 2010

I have a control and list of variables and I want in the control property to be assigned to the variable value directly in the page not from the back code, something like this

My global variables

public string Banana = "banana_pie";
public string Apple = "apple_pie";

in my custom control instead of:

<uc:LoadPie id="pieBanana" type="banana_pie" />

To this

<uc:LoadPie id="pieBanana" type="<%=Banana %>" />

so is there a way or just assign the property in page back code.
