I'm doing such a small web page that contain 4 main HTML div which should contain last 4 NEWS from a SQL Database.so I've designed them, and put in each on a label control, and an Image control.and to bind information from the SQL to them, I've used (DataView) object, and using a loop from 0 to 3 I've get the data I need.but I believe that way is not the perfect one! so I need something more clear and effectiveness!
View 4 RepliesI am new to asp.net. i am just trying to get database query result and store it into label Text in c#. Is there any way to do that?
View 5 RepliesI have a label inside a formview that is not bound to anything.
Lets say I have a table of customers (with a key field called CustomerID), and then another table that has all their orders (with amount spent per order (OrderID) - based on CustomerID)
On the FormView there is a key field (CustomerID) (this is to be used as an INPUT parameter to a SP - which is to return the SUM of all the customers (Order_Totals). I could nest a view within a view I suppose to get this result, however, I just want a label to simply show this ScalarValue.
Basically, I want the label to show the aggregate (SUM) total amount each customer has spent on all orders. I have a SP called SumCost with two Fields (one a grouped by field CustomerID and the other a Summed Total of each customer's orders SumCost)
SELECT [SumCost] FROM [SumCost] WHERE ([CustomerID] = @CustomerID)
I test my SP and it works great, returning the value based on CustomerID - no problem.
My problem is getting the CustomerID passed into the SP on runtime (do I put it in FormView2_Databound) and putting the value into the label (CustTotalLbl) which is inside this form.
I have been messing about with this for hours surely this should be an easy task ....... I have a stored procedured that creates a invoice on a Quotetable one of the parameters is a output parameter Invoice Number this is passed to a label. (Label1) This works great.
I then need to add items to the invoice on a item table so my next stored procedure should take the value of Label1 and update the foreign key quotenumber on the itemtable with the value from label1.
On the aspx page I have a small section for a gridview which shows the current quote with however many items on it using the control
[Code]....
On the ASP page the control for @Quotenumber = Label1 but I get the following error
'Conversion failed when converting the nvarchar value 'Label' to data type int.'
This is my MS Sql query
sqlcommand cmd= new sqlcommand("Select Date from Table",con);
sqldatareader sdr=cmd.executereader();
while(sdr.read())
{
label1.text=sdr["Date"].tostring();
}
Here im using Date column datatype is datetime.. after executing this query on button click itz show something like this: 04/14/2010 12:00:00 AM but i want only Date like 14-Apr-2010.
I got stuck in the following problem. I am using cascadingdropdown ajax control and binding data into dropdownlist from database. I have done to display the data from database. Now I want to display the data, which is related to the item which I selected from dropdownlist, to 'Label'. ex) I have a following table in database.If I select '2' from the dropdownlist, I want to display 'Taro' to the label. If '1' from the dropdownlist, 'Ken' to the label. ID name 1 Ken 2 Taro I changed 'AutoPostback' property of dropdownlist to TRUE,then when I run the page and select the item from dropdownlist, error occured. Error messege is as belows. Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. Event validation is enabled using in configuration or in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. If there is another way to display the item into a label without postback, or someone knows how to sort out this problem,
View 2 RepliesDoes anyone know where I can find some info on how to support data binding in my control? I would like to get data primarily from a sql server.
View 3 RepliesWhat's the difference between binding for example a column called ("Name") in both cases ? and is there's any performance difference ?1- Assigning the data in the mark-up
<asp:Label ID="Name_Lbl" runat="server" Text='<%# Eval("Name") %>' ></asp:Label>
2- defining a control object for every control inside the repeater ItemTemplate and find it and then assign the data in the column "Name" to ite.Item.FindControl("Name_Lbl")
sql_select = "SELECT auid FROM tbl_auAccount WHERE username='" & IUN & "'"
'Add Error Trapping Later
con = Server.CreateObject("ADODB.Connection")
con.Open(data_source)
'Execute the SQL Command
con.Execute(sql_select)
'Close the connection
con.Close()
con = Nothing
Now this works and I was able to put the value into a dropdown list box, but I need the value returned placed into a label such as:
lblShowNewUserID.Text = ? (? being the value returned from the Query). I thought this would be simple, but it is not (at least for a newbie like me). NOTE: (I will have instructions before this to be sure that only one value will be returned and taht the value will not be null).
I am creating a website that reads and writes from SQL Server 2005.
I am able to write to the database but I can't retrieve that data and display it in a label.

View 3 RepliesI would like a title label to only be visible if the bound data label is not empty.
<asp:Label ID="TitleLabel" runat="server" Text="Title:" /> <asp:Label ID="DataLabel" runat="server" Text='<%# Bind("Data") %>' />
So if there is no Data incoming to the DataLabel then I want both labels to be invisible.
I have Template fields configured for Gridview. The gridview is using an objectdatabsource to bind itself. I have the gridview configured to use Templatefields which then contain tables to display the information. This works fine.
My question is, is it possible to change the text of the label if certain criteria is reached. If "NumberOfDwellings" is 1 then change the label to read, "1 Dwelling". Where-as if NumberOfDwellings has more than one then it's "3 Dwellings".
<asp:Label ID="lbl_NumberOfDwellings" runat="server" Text='<%# Eval("NumberOfDwellings") & " Dwelling(s)" %> '></asp:Label>

I have image control in my page I want bind it from DB how i can do it?
it is not in datalist or gridview
<asp:Image ID="Image1" runat="server" />
I have a control inherited from datalist because I want all the same functionality but with a couple of extra properties.
I have a method that goes off and gets the data inside the control (instead of using a separate datasource ID). It's reading it from XML into a datatable.
If on the code behind of the aspx page I put the control on I put a thecontrol.databind() in the page load, all works well.
However I'd rather not have to do this, instead the control should bind itself.
I gather it's something to do with the order of events but I'm not sure what to do about it.
I don't want to reinvent the datalist wheel, just add a couple of properties and get it's own data

I've done a asp.net application to generate reports over a particular data. Initially i created local reports (.rdlc) to generate reports. I created separate .xsd for each rdlc and designed the reports. I build the dataset programmatically and bind it to the rdlc. I used the following code for binding the datasource to the reports -
rptMyReport.LocalReport.ReportPath = Server.MapPath(srdlcName);
rptMyReport.LocalReport.DataSources.Add(rds);
Now i have converted all the rdlc to rdl following this msdn article and i've published the reports to the report server.
rptMyReport.ServerReport.ReportServerUrl = new System.Uri("http://ReportServer/ReportServer");
rptMyReport.ServerReport.ReportPath = "/ReportFolder/ReportName";
Now how can i set the datasource to the reports programmatically?

Quick question here. I'm sure it's possilbe, just can't get it to work.
I've got a gridview. In have a gridview. The gridview is bound to a list of my custom class. The class exposes a link to an image as well as the image's height and width. I have a Image Control in the gridview. I've bound the Image Url to the correct property. Now, I'd like to bind the height and width properties as well. But everytime I do that I get the following error:
Cannot create an object of type 'System.Web.UI.WebControls.Unit' from its string representation '"<%#Bind("GetImageHeight()")%' for the 'Height' property.
Here is an example of the tag:
<asp:Image runat="server" ID="imgProduct" ImageUrl='<%#Bind("ImageUrl")%>'
Height="<%#Bind("GetImageHeight()")%>" Width="<%#Bind("GetImageWidth()")%>">
</asp:Image>
