I am creating a web application that displays URL to users in a GridView. The application has a code behind that will be doing the processing before it can return me a URL. This is done in a loop. So it looks something like :
[Code]....
What I wanted is to make the Gridview always update the rows everytime an item in the loop is done instead of waiting for the loop to finish.
For now, the application will only display the whole table until the code/loop finishes. I'm very much aware that this will happen because the web page is static in the first place. Does anybody know how to do this?
I have tried of using iframes(I thought of reloading the frame so the whole page wont reload again and a new GridView table would appear because of the code in Page_Load event because I tried placing the data in a separate static class and the GridView.aspx page will just retrieve the values upon every reload)
and I'm not sure how to implement AJAX/Javascript with this. Is Animation involved in this kind of situations?
I have a Gridview connected to an Access database using a Datasource and a query SELECT * FROM [Staff]. In order to update the grid view I have to do it in the IDE and click Refresh Schema. I have tried:
StaffList.SelectCommand = "SELECT * FROM [Staff]" StaffList.UpdateCommand = "SELECT * FROM [Staff]" StaffList.DataBind() Staff.DataBind()
I have created a gridview at runtime. its working fine when i load the grid first time. after when i am selecting next value from ddl to load grid according to that option(selecting from dropdown list and coresponding values showing in grid) showing error that "A field or property with the name 'datafield name' was not found on the selected data source."
might be i am getting this error becuze the privious value is not being cleared"

my users haves different permission: some users can delete, and some users can editing in a gridview how can i allow this at specified users? and hidden the button ho allow the delelte or update record?
You know how when you put your cursor over the line that seperates 2 columns of a grid, the cursor turns into a 2 headed arrow and allows you to adjust the width of the column? How do you allow this with a gridview?
Query 1 - Grid View: - I have an excel sheet which I import into gridview at runtime. For excel sheet import, I have a fileupload dialog box and an asp.net button control which when clicked imports the sheet contents into a gridview. The problem is I have my fileupload box and button control in a page called Default.aspx and I need the gridview get displayed maximized in a new page called Default2.aspx.
Also, I need to specify the row number of the field titles from the excel sheet dynamically at runtime so that the gridview appends any new field/column from that row on. The excel sheets I use contain complex formatting. Is there anyway to display the excelsheet contents as they have been defined and formatted?
Query 2 - Sessions: - I add nodes to my treeview dynamically at runtime. Since HTTP is a stateless protocol, the changes which I do remain only for that session. How do I append the changes I do to the treeview simultaneously in the code?
- I have appended 2 extra columns into the excel sheet generated gridview which take input through dropdownlistbox control at runtime. How do I update and retain those changes in the gridview?
I build a DetailsView and assigned datasourceID= SqlDataSource1
I bulid select command at runtime.
string selectcmd = "SELECT * FROM CDInfo WHERE CDID=@id"; SqlDataSource1.SelectParameters.Add("@id", Request.QueryString["id"]); SqlDataSource1.SelectCommand = selectcmd; //The only problem is that I try to call the select method //but the compiler tell me I have to add a DataSourceSelectArguments SqlDataSource1.Select(); //I don't know what argument to add, so I put DataSourceSelectArguments.Empty // But it says variable "@id" must be decleared //I don't Know what's going on.
