Forms Data Controls :: Data Structures Can Be Used As Data Sources For Gridviews?
Mar 31, 2011
so I know that DataTables are often used as the DataSources for gridviews. Lately, I have found that I can also use generic lists as data sources for gridviews. But I figured that out by simply trying it to see if it worked.
I have looked all over the web and simply cannot find any kind of inclusive list or description of exactly which data structures can be used as the data source for a gridview. Does anyone know if there is such a list, or some kind of reference that I can look to for this info?
Although it sounds like an obvious question, like there is obviously one out there and I just haven't looked, my experience has been that it's just not so.

I have a stored procedure written using dynamic SQL in the SQL Server and I am calling it on the code behind and adding parameters to it and filling a dataset and binding the data set to a Gridview. But I am getting this error when I bind it.
Can someone please tell me how to fix this?
It used to work fine when I did not use dynamic sql.

I need to display some data in a gridview. Its shipping data.
Part of the data can come from a generic database query. Static shipping data that can be looked up from the database. Part of the data is external and has to be queryed from USPS. Any suggestions on what is the best way to accomplish this.
Should I just programmatically fill the gridview from the code behind doing the database lookup manual and filling the gridview with manual data then going out and filling the rest of the gridview with the data obtained from the USPS service?

We are using a tierd design with a Data Access Layer and classes for everything we need. This serves as an advantage because we do not have to write querys over and we can separate the Presentation layer from the Data Access Layer and Business Rules.I have always in the past populated GridViews, DataLists, repeaters,etc with SqlDataSources. This is what I have become accustomed to and I feel like it is simple. For querys such as Select * from Members, I feel like using a DataSource is simpler than having to go in the code and calling methods to populate and DataBind these presentation controls.
I am working with a gentleman who has introduced me to the world of Data Access Layers and we are breaking everything down into simeple, but effective queries to populate controls and do what we need to accomplish with this application. He is not very approving of using any type of DataSource. We are disagreeing on the time and place to use these class methods to call the database.So my question is, which is more widely used in the programming world? Do most people use DataSources to populate presentation controls regardless of the Data Access Layer they are working with? Which type of queries are best suited for a DAL - simple, populating queries or complicated joins and upserts?

I have a complicated report that nests six deep and so really hits the database hard. I want to use SqlDataReaders NOT DataAdapters and DataSets because I don't want big tables in memory.
MARS can get me the data fast, all from the one connection. But all the examples show it binding to a treeview.
I want to bind it to nested GridViews (six deep!).
Any examples of MARS binding to nested gridview/list/repeater controls of any kind?

I need to create a query which does a join between two tables which are in different databases. I can easily connect to each database, and write queries in each, however, I can't seem to find a way of generating a query which does a join between two tables from different databases.

I have this "how to" type of question. I have a page where there are four gridviews. Now these four grids pull data from four different tables. The 1st grid retrieves data from table 1 with a where clause in it's query that comes from a hidden fileld value in the page. Till this things are fine. However, the 2nd grid has a dependency on the 1st grid and the where clause in it's query should be the data selected in grid view1. The 3rd depends on the 2nd one..and so on.

I do have a page that is literally overloaded with about 10 GridViews and there is a datasource for each particular one. Now, each GridView is hide inside a panel, so I only display one at a time depending on what is it that the user request. My concern is the followng: Even though I am only displaying one GridView at a time, do the others datasource are still working behind the scene on the blind side and therefore are putting a load on the server and on its performance. Or I do not have to worry about this because as long as the Panel.Visibility = False, nothing inside that panel is working.

I'm developing a bilingual web site, and therefore, I'm changing the text of the headings and the select buttons of my gridviews. I just discovered that if I set some code like below in the rowdatabound event of the gridview, the "linkbuttonish" headings get replaced by unclickable text. In another thread, I was told to change
If Session("lang") = "en" Then
If e.Row.RowType = DataControlRowType.Header Then
e.Row.Cells("name").Text = "Given name"[cod]...
in the myGV_DataBound sub.This works well, but not everywhere. A few gridviews are populated from codebehind, and this is where things go wrong. What happens is that - nothing happens (it's still the original heading). I added a Watch, but once the HeaderText property changed, the Watch never yielded another result, but stayed with the new value.
Now I suspect that even though the HeaderText property has changed, this doesn't get reflected in the GV when populated from codebehind.
I guess that I should write something else than "e.Row.Cells("name").Text" to still have the click-behaviour, but I don't know what.
The same question arises for the select linkbutton in a cell of the gridview's datarows.

I have a project I am doing where clients post the sale of tickets. They are stored in a DB and shown in a gridview when they login to their account. However, I need to figure out how to set the gridview to only show what they have posted. I know I can use the their login clientID(CID), but I can't figure out how to get the gridview to show post for the client that logs in. It will either show all the post by multiple clients or it won't show any at all. I am using response.redirect(clientlisting.aspx? & "CID"). I then set the where clause as ticketID(TID) = querystring to (CID) but it is not showing anything.How do I set the gridview to show only post by each individual client?

I am needing to display two gridviews in the same panel on a form. Each of the gridviews has their own sqldatasource. Both datasources pull from the same table but they have a different record selection. When I view this in the browser I only see one gridview displayed. Can someone tell me how to do this or is there a better way to get a two gridview look without using the gridview?

I am trying to loop through all gridviews on a page to hide them and set their page index to 0. This should be very easy to do and it seems like the code below should work but it doesn't?? How can I accomplsh this with the least amount of code? FYI- this code is executed on a button click.
foreach (Control childControl in Page.Controls)
{
if (childControl is GridView)
{
((GridView)childControl).Visible = false;
((GridView)childControl).PageIndex = 0;

Why is it when I select an Order and the second gridview pops up theat it moves my text and Ship button down? I thought I had it setup in the tables so this wouldnt happen?
