Forms Data Controls :: Databind Refresh - Records Left In The Table And goes To The <emptytemplate> ?
Feb 9, 2010I have a gridview, and I set the datasource in page_load to a linq query. I have delete linkbutton in the grid and am writing code in gridview1_rowdeleting event to delete the record from the table and all its records in child tables. Works fine, except when I databind() after the deletes to refresh the grid, it thinks there are no records left in the table and goes to the <emptytemplate> . There are in fact many other records that should appear. When I go out of the gridview and come back in, everything is fine. The proper records have all been deleted, and the remaining ones show. Here is the code. the table being displayed is Schedule. It has child records in the two other tables.

This is from Page_Load

Use Databind Records In Inline If Statements?
Mar 10, 2010I've got a repeater on my asp.net (VB):
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("Question_Number") %>' />
<%#Eval("Question_Desc")%>
Now what I want to do is, check a value that I haven't used called "Question_Type" which could be = 1, 2 or 3 depending if it is multiple choice, short answer, etc. I have tried this:
<%
if Eval("Question_type") = 1 then
Response.Write(" <asp:RadioButton runat=""server"">test1</asp:RadioButton>")
Response.Write(" <asp:RadioButton runat=""server"">test2</asp:RadioButton>")
Response.Write(" <asp:RadioButton runat=""server"">test3</asp:RadioButton>")
end if
%>
and I get this error: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. HOW can I use this value in a if statement?

View 6 RepliesForms Data Controls :: Gridview Not Refreshing After Databind?
Jun 26, 2010I'm working on a project where I have to create a page that displays the "health" of a system. I run a query and display the results in a gridview with a red or green icon next to it. This works fine when the page is first loaded. My problem is that I have a thread that runs a query every 30 minutes and rebinds the gridview but the gridview never refreshes even though the data has changed. How do I get the gridview to display the new results? The databound event never fires a second time even though I can clearly see that I have received new data. I assume I am missing something simple but I just don't know what. What am I doing wrong?
View 5 RepliesForms Data Controls :: When To Call DataBind On GridView
Sep 2, 2010So I have a GridView and several events that can be triggered (such as filtering and inserting a new record) to manipulate the GridView. I want to make sure that I'm not calling DataBind on Page_Load, especially since I might have to call it again when certain events fire. Is there a way I can make it so I only have to call DataBind once on the GridView after Page_Load and anything else has fired? Like some event that will absolutely fire last where I can put my DataBind?
The reason I need to do this is because the DataSource for the GridView is set programmatically from a DataView when the page is loaded, so DataBind needs to run every time. Just, hopefully, not multiple times each time...
Forms Data Controls :: Position GridView After DataBind?
Mar 7, 2011I have a gridview positioning issue that may have been answered elsewhere, but I couldn't seem to find a similar post...
I have a webforms app containing a paged gridview (e.g., 200 records - 50 rows and 4 pages).
When the user clicks on a button in a specific row, another web page is launched to process that button click. When the user closes that page to return to the main gridview, the databind event is rerun and the page redisplays the gridview starting at the top. However, I want to have the previous position maintained (like an html bookmark), so that the grid will automatically be scrolled to the the previously clicked gridview page and item.
Setting attributes such as "MaintainScrollPositionOnPostback" do nothing in this case.
Forms Data Controls :: Cannot Trigger A Postback / Databind Of Gridview
Apr 23, 2010I am have a page with a couple of dropdowns which serve as criteria for a select SPROC. Once a selection is made in a drop down a panel is shown which contains gridview whose rows have been returned by the select SPROC.If you close the panel and change the drop down selection and then redsplay your panel the data from your prior selection is still displayed in the gridview,
unless you page to the next group of records.

Forms Data Controls :: DataGridView Equivalent Of GridView.Databind()?
Nov 12, 2010I have spent most of my time writing ASP.Net web pages, using VS 2005. I am now developing some client function for Windows, so I'm relatively less expert in VB.In my Windows program I have defined a DataGridView and linked this to a data table (within a tableadaptor). Now I want to populate it: on a web page's code-behind I would write Gridview.databind(). What is the equivalent with a DataGridView.

Forms Data Controls :: DataBind A Gridview After DropDown Change?
Aug 21, 2010I have a drop down menu that is populated on page load. Below that, I have a gridview that has a select parameter based on that drop down menu's value. I can't get the gridview to populate with data based on the drop down.

Forms Data Controls :: GridView - Databind To A Collection Within A Custom Datasource?
Jun 14, 2010I'm trying to databind my GridView to a custom datasource where one of it's members/fields is a collection.
Custom object Entry
public List<EntryHour> Hours { get; set; }
In practical terms, one row consists of some normal text fields which is easy to handle. However, the Hours field is the nut to crack.
How do I, in the GridView markup bind my textfields in question to the Hours field (which consists of 7 items allways)?

Forms Data Controls :: Entity Framework Using 2 Tables Databind() To A Gridview?
Jun 16, 2010I am new to Entity Framework and working my way through it little by little. I think I have it figured out on how to get data into and out of 1 table at a time now the challenge is 2 tables into a gridview.
I have a user table that has a list of threads that a user can mark to track. Easy enough. Assign the userid number & threadid to a table with a push button while the user is logged in and viewing any of the posts that are on that thread. The new challange is to get only the posts that the user has marked to track. SQL easy. Entity not sure what to do.
If I make a view or stored procedure and add it to the database that would be an extra step. To join the 2 tables as in sql Select posts from posts where track.userid = @userid join track on post.userid=track.userid Seems Entity was made to avoid this type of thing. Than once the data is gathered I need to bind it to a gridview()

C# - DataBind User Controls In Gridview?
Jan 26, 2011I got a GridView in ASP.Net in which a user control is placed:
<asp:GridView ID="GVWunitcollection"
CssClass="gridview"
runat="server"[code]....
I bind the GridView to a List<T> filled with custom 'Unit' Classes. Each Unit consists of several properties to fill the usercontrol. (The user control holds a table, and some labels and textboxes).How can I achieve this? Is there a simple way to bind each usercontrol to the appropriate Unit?By the way, this is my way to mimic a "dynamic" behavior of multiple usercontrols on a page. If there's a more simple way, I would like to know how!
