ADO.NET :: Passing A Particular Data From A DB To A Label Control?
Sep 30, 2010
I have a dropdown which shows the NAME from a database. when the user selects the name, I need to display some of the data of the selected name to 3 Label controls. the data in particular are IDnum, Address and Status.
Here's my code.
[Code]....
How do i now display the values in my Label controls?
I have written a DLL. My intention is to use the DLL in both .NET and ASP.NET. How can I pass a Label control (or any other control) to the DLL as a parameter.
I would like to use the gridview paging feature and have built a gridview with a user control. The data source has lots of columns, so to make it easier I want to return a LIST<MyObject> and just pass <Myobject> into the user control rather than all the data elements. Not sure how I access the object of the data source to bind to the control. Assume it would be during ondatarowbound.
Also, my guess is there is a better way to do this than gridview. I'd take either solution that allows me to have easy paging and pass the complete object into the user control
I have a Calendar Control which is getting certain dates from SQL database and shows them in gray colour using following SQL statements:
[Code]....
[Code]....
Everything works fine but I want to Show Location and Date also under the calendar control usnig Label control so when user clicks highlighted date it shows Date and Location (only the ones which are coming from SQL database and are highlighted) using Label control.
I need to be able to evaluate the text value of the template button or pass date from the dbDateOpened colum when the button is pressed. Either direct I have tried gives me an compile error. With the current configuration I get this error. "Object reference not set to an instance of an object."
In my asp.net web page i have a dropdown box. Say like i have to bind EmployeeName to this dropdown box to show up as items.
I am using a dataTable to bind to this grid by having two columns in DataTable (EmployeeId and EmployeeName). But i am only binding the EmployeeName to the dropdown list box.
In the UI, after the user selects an Employee, I need to pass that employee's id to a function. Is there any way, i can directly pass the underlying data (EmployeeID in the DataTable attached to this dropdown), when the user selects the EmployeeName from the dropdown. Or i will have to make a roundtrip to the database and get the selected Employee's Id and then pass it to the function.
I have tried almost evrything and nothing seems to work,,, I dont see errors but the code is not firing when I bind in the properties of the button control ,,nor the code behind.
i have a linkbutton inside the Datalist control while i am clicking i would like to pass the ID value of the corresponding Link button. How can i pass the id value for the onclick function?..
In my project, I need to create a user control to handle the sorting and pagination of all the grids in the application. The grid however will be different in different pages with different formatting.
I am able to do this by exposing a property from user control which takes gridview as the input.
then in page load, i bind this grid, and assign the sorting and paging event handlers to this gridview variable.
This way I am able to do the sorting and paging, but the problem is I have to bind the grid in all the post backs, and then in the sorting and paging events.
So when a user sorts, I have to bind the grid twice, once in page_load and then in sort event of user control.
I can store the first set of records in viewstate and bind that in page load, but is there any other way, so that i dont need to bind the grid in all post backs but only inside of not postback.
I have a store procedure. I show the result in the grid view, I would like to know how I can show each fields in the label so I can place them anywhere that I like in the page.
I have an UpdatePanel with a button and a label. Inside the button click event I call a web service which returns a string. I then want to append that to the label. Simple! Except that it doesn't work. I can change the label to a value I set inside the click event but when I try to add the web service string it doesn't work.
I have been trying to override the PreRender event, to use a ViewState, to set EnableViewState on the Label to be false. Nothing. Works. At All. If I set a break point inside the OnPreRender override I can see that lbl1.Text is being set to the value that I want (i.e. the value from the web service) but it doesn't appear on the browser.
Here I've a listview control whose datasourceid is set to one sqldatasource, listview contains a panel in a itemtemplate region. In the panel there are some lables which are bounded to the column present in sqldatasource. But In one label I have to assign some other value dynamically. can any body tell me how to access that label and assign value to it. Here's the code
I want to make Image Gallery on label control where each row will contain 3 images. I also want to use javascript ligtbox on image click event for show the image in larger size.The Path Of the Image is stored in database.
I have a databound label control (i.e. Label 3) inside an Item Template that's in a DetailsView control. I just need to get the value of those label and compare it to some string. I tried several ways (i.e. Find control, DetailsView.Row) but nothing seems to work. I don't know if I'm using the FindControl methos correctly or if I need to access the Row first and do the findcontrol method.
