I have an ASP.net web page with VB code behind linking to an MS SQL DB. On the web page I have 4 DropDownLists and 1 GridView. Each DDL is populated with a SELECT DISTINCT query on 4 corresponding columns from 1 table in the DB. What I would like to be able to do is: when any of the DDLs have their selected item changed the other DDLs are updated. Crude example:

How do I filter my DataGridView with multiple checkboxes names? I want to filter in which region the suppliers are located. ex. RegionTable.Regionrow. And I have 4 different regions(checkboxes text name) I want to filter with. Compatible to use multiple choices in filtering.
So. Checking 2 of the 4 regions and pushing the filter button should filter the gridview after checked checkboxes. I have tried different methods for 4 hours and search the net but can't find any good method.

I am creating a web application in ASP.net/VB.NET and I have an issue with the gridview.Currently, I have the gridview populated with data from the DB and I've also coded the update button to allow the user edit any necessary information through a form that pops up.[URL]...
What I'd like to do, if possible, is add a button to the two right columns(I already put one in the Dock Out Time column) which will be invisible if the column is set or will set the current time to the column. Setting the time for those two columns is already handled through the update form, but my supervisor asked me to try and see if this was possible.
Those two Time columns are Templatefields(since I format the display time from what is actually in the DB) and I added an asp button in the ItemTemplate for that Set Button in the picture.Is this even possible to do and if so, how would I access this button in the code behind so I can add functionality(setting the time and hiding it if the column is not null)If it's not really possible to have two items like this in a templatefield I can just make 2 extra columns for these buttons but I think this would look much cleaner.
i want to filter row and put it in a textbox and filter another row in another text box vb.
ex.
ID--------- Date -------- msg_num ------------ Message <<
10001 -- 01/01/2012 ------ msg1 ------------- Blah! Blah![code].....

I would like my gridview to be filtered by the dropdown list I have. It is pulling specific information from the database, so when you choose a value from the dropdown list, it should search through all the records and find only records with the ddl value in them.
The code that I am using in the codebehind for the SelectedIndexChanged is not right though. I get an error message saying 'Value' is not a member of 'Integer'. This is on the line dsCompanyFilter.SelectParameters.Add
It probably has something to do with the gridview not tying to the dropdown list properly, but I am not sure how to fix that code.
<asp:Content ID="Content2" ContentPlaceHolderID="body" Runat="Server"><br /><br /><br />
<asp:linkbutton id="btnAll" runat="server" text="ALL" onclick="btnAll_Click" />

This post is similar to one I have posted before about a dropdown filtering results in a gridview. Well now I need this dropdown to attach itself to a repeater that will filter results into a gridview. I have tried rptLetters.DataBind() in the code behind of the dropdown list, but that doesn't seem to be changing any of the letters at the top of the page when I click on different items in the dropdown list.The screenshot doesn't show enough of the products, but in this case it skips from G to L, and in the repeater the letters between G and L are still shown. I need to be able to get that repeater to recognize the letters that start each of the products associated with the company chosen.
<asp:Content ID="Content2" ContentPlaceHolderID="body" Runat="Server"><br /><br />
<asp:linkbutton id="btnAll" runat="server" text="ALL" onclick="btnAll_Click" />

Autopostback works but when one dropdownlist is selected the page refreshes. When the user select one dropdownlist, another dropdownlist will then populate if not its empty. After submitting the form, selecting dropdownlist will remove all the validation message. What i want to achieve is to have javascript to manually postback instead of using autopostback so that the validation message will still remain after selecting from dropdownlist but

Could not find this through Google or in SO questions.I have a checkbox listbox on my form. I want to filter my List by the list of selected Ids from that listbox that are checked, in SQL I would have done this like "Where TypeId In (1, 4, 5, 7)"... how do I do that in LINQ?
I feel like I am missing a really obvious answer, but cannot get it.
For argument sake... here is the what I have for sample data:

ID, Name, TypeId
1, Red, 1
2, Blue, 1
3, Green, 2
4, Pink, 3

How do I combine the following two similar statement into one. They are similar in the sense that they both get input from the same textbox:

I have tried couple :
Me.ReportsQueryBindingSource.Filter = "StudentID = '" & txtSearch.Text & "'" Or "ParkingSpaceID ='"& txtSearch.Text & "'"

I have a datatable loaded from a database. I bind the datatable to a gridview on page_load. Now I want to filter the gridview by a user selection so I made a checkboxlist and wrote some code as follow at CheckBoxList1_SelectedIndexChanged

With this code above, it can filter if there is only one selection on the checkboxlist. I try to loop the checkboxlist myself but always ended up in errors. Hope someone can help me out to make this work.
This post is a continuation of my other post concerning 'List(of) with multiple comboboxes refill problem.'. I threw the list overboard and began anew with a Dataview.
So far I (finally) managed to get 2 comboboxes (will be more, but if it works for 2...) loaded with the same data using different dataviews (DataView1 & DataView2) so I can select a value from each combobox without the other following the selection.
But now I want to filter out the selected value from the other combobox.
This also works.
The only thing is this: If I select in combobox1 the value 3, and select in combobox2 the value 4, combobox1 will change to the value 2.
If I select in combobox1 the value 2, and select in combobox2 the value 1, combobox1 will change to the value 3.
It works also the other way arround. I can't seem to get my hands around the problem..
Does somehow the index of the items in the combobox play's part? I don't use the selectedIndex, so from my point of view it can't be..
The code I use:
(with the item 0 as 'neutral' option)
Public Class Form1

In my datagridview there are two dependent columns, one is category and the other is items. So I want to filter my item column list as per selected category. But the problem is that when I change the category wise data to datasource of items combobox, previous selected items names disappear because previous items is not in current datasource.
