Forms Data Controls :: Populating A Grid View With Data From SQL Datasource?
Dec 22, 2010I'm populating a grid view with data from an SQL datasource. The database has a a list of performing artists and lots of details. The gridview initially, shows the ArtisID (Primary key) , and artist name and music style. So far this is all simple and easy. This is done.
Now I want to be able to click on the ArtistId (Select Column) and move the customer to another page where I show indepth details about the artist. How do I do this???
In Vb.net I had a 'Celldoubleclick' event, and I redirect the client. But how do I accomplish the same in asp.net? I already have the primary key value
primekey = datagridview.selecteddatakey.value
Forms Data Controls :: Dynamically Populating Fields In A Gridview Depending On Data In A Table?
Jul 17, 2010I have a gridview that is populating from a SQL DB and working fine. However, based upon certain data I find in fields in the SQL table, I want to place a 'n' or a 'y' in extra columns in the gridview that I am assuming need to be templatefields. My thought was I could maybe add 8 template columns and then I could put a 'y' in the appropriate column based upon the data I find the table. For the life of me, I cannot figure out how to do this. I want to do this at rowdatabound time ( i think) but I just cannot find out how to, in my code, put that 'y' in the columns. Is this the right way to do this or do I need to do it another way? How do I get that 'y' in the proper column?
View 3 RepliesPopulating A PDF Form With Data From SQL DB Table
Jan 4, 2010I'm writing an app (ASP.NET 2.0 w/ VB code behind) where my users complete a sign up process. Their data, such as name, address and phone info is stored in a SQL Server DB table. What I want is for them to be able to click a "Print Authorization" button that auto populates the authorization.pdf form and then let's the user print out the form to sign it.
How do I populate the Authorization.PDF with this info from the SQL table? Basically, I just need to know about putting the data on the PDF and then having it print. The file doesn't need to be saved, just populated with data and then printed. I have no experience with C# so the iText solution really won't work.

Accessing One Table Data From A Database And Populating Data In A Datagrid
Mar 16, 2011Okay, I have developed VB.NET winforms applications and I understand that working with ASP.NET would be similar. However, this seems way complicated then I thought. Basically, i am working on accessing one table data from a database and populating data in a datagrid. I have few text boxes on the display page and if a user clicks on submit button i want a new set of data with new select statement based on user input.
I don't quite understand how the textbox value can be passed on the same page and a new select statement is generated, which then populates the datagrid.

View 2 RepliesData Controls :: Populating GridView With Two DropDownLists
Sep 11, 2013I have two dropdown lists that I am using to filter a gridview. I gridview is populating based on a query
select [AnnotationNumber],[AnnotationBy],[AnnotationType],[BusinessUnit] as Unit,[ErrorType],[ActualAgencyError],AnnotationComments,[sgkComments],[ActualAgencyError],Cust from vw_GridviewSource where Name = '"+@Name+"' and AnnotationDate = '"+@Stage+"'";
SqlCommand cmd = new SqlCommand(query);
gvSummary.DataSource = GetData(cmd);
The @Name and @Stage variables are the selected values of the dropdownlist. When I start I get the two drop down lists on my webform. When I select the values from the dropdownlists, nothing happens. I get no gridview. I added onselecedindexchange event both dropdownlists and even after both are selected nothing. I debugged the code and found that there is a point where the value is correct, but I still don't see the gridview. I have alsochecked the query associated with the databind and it works perfectly when I check it in SQL. I am enclosing all the code from the aspx.cs and aspx.
