Filter Data Based On The Drop Down Filters?
Jul 27, 2011
I am looking to find the best way to do the following: Filter data based on the drop down filters, as long as I am within the same product category (e.g. toys, puzzles, etc...), but in different web forms (product grid and product detail).So if I select toys under $25, I need the filter to the toys in a grid format, but if I click to view the detail I need the filter information so I can filter the related items display.Display certain filters depending on the product category.Right now I believe that if I build a user control and session variables that I should be able to accomplish this.
EDIT: Right now I am using the page_load event to update the data and would like to avoid AJAX for right now.

I have a filter row on a Grid View and I need to find a way to populate the drop down list so that I can use the drop down list. The Dev Express website achieves this through binding it to a data scource on the page, I need to find a way to do this but through the code behind.[URL]..

I am writing an app that reads from the com port, filters the data, then writes to the text box, then immediately starts over. This all takes place in an endless " do while" loop within the "start" button code. I also have a end button too which closes the com port and ends the program. Some other buttons are present also to change the filter settings.Problem is when I click start, data is logged, but none of the other buttons work. Also some of the text boxes are "see through" and dont look like thy have updated with the rest of the form.

I am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.

I have a datagridview that's taking a while to load because my table contains almost 5000 records. How can I provide an easy way for clients to filter the grid based on a product name. I was thinking of having labels with each alphabet on my form and when they click a label it filters the bindingsource according to the chosen alphabet. this seems like an awkward solution though.

I have a database with a table that is a child to many other tables. I am using this child table as a datasource for a datagridview. I am using comboboxes to display specific fields in any parent tables, instead of the user seeing the foreign key. Everything is fine. However, I would like to filter the BindingSource based on text matches between any of the fields in the child table and the corresponding fields of the parent tables.

I think my question is discriptive, or as Microsoft in the Documentation for Data Grid the question is, How do I have a combo box column display a sub set of data based upon the value of a different combo box column?

I have a form with 4 comboboxes and a button. The first combobox is enabled, but the rest of the controls are disabled. When the form is opened I fill the first combobox (cbxMethod) with a datatable. When the user selects something in cbxMethod the next combobox (cbxStudy) will be filled and so on. When the last combobox (cbxAnalyte) has a selected value I want to enable the button and give it focus so the user can move forward with the program. I basically want to force the user to move from one combobox to the other, until all are filled.I am currently using the SelectionValueChange event, but this event only fires when the user changes the value with their mouse or hits the Enter key, not when the user hits the Tab key.

I have a table (Projects) which is linked to projectVersions on projectID..projectVersions contains several columns on which I'd like to filter a returned project (and associated projectVersions) list. For example there is a "capacity" column and a "country" column. I am doing a filtered list of projects on one page and I'd like to include all projects where any one of the associated projectVersions has a capacity of 750ml and a country of "France" for example.It may be that a particular parameter is not set and so I pass a zero to indicate not to filter on that.I guess this needs some kind of subquery as when I try and do something like this: [code] it doesn't work as the "xxx" bit, being one-to-many, expects me to specify an item to get at the entities within and yet I want to query where ANY of the associated versions match one of the criteria.

I have a dgv and in it the user can move around column's or resize columns or filter columns. Now there's an issue when the user try's to move the column's around because you have to click on the column and drag it over. But once you click on it, it sorts that column in ascending (or descending) order.

is there any possiblities like this select two conditions in one dataview like
Childds.Tables("ColumnList").DefaultView.RowFilter = customername='hello'
dv = Childds.Tables("ColumnList").DefaultView()
it has given correct answer but
Childds.Tables("ColumnList").DefaultView.RowFilter = customername='hello' or customername='hai'
dv = Childds.Tables("ColumnList").DefaultView()
In this case it takes only first one and ignore the second or condition
how to write the rowfilter to select when the customers are multiple

I want to filter data on the textchange event on listview so I use dataview to filter data. Issue in the below code is, I use dataview inside for each so that it checks only one condition that is last value only it takes, I want to check value in s1 with dataview and remaining value should bind with listview. E.g.: if I type an in textbox it should list all the item values starting with an value like anandha kumar, anna etc. Suppose I keep the value anandha kumar and anna in array s1. I should list all other values expect the array values like antony etc... in listview.
protected void TextBox1_TextChanged(object sender, EventArgs e) {
dvProducts = (DataView)Session["ListViewItems"];
string serachText = EscapeLikeValue(TextBox1.Text);
string lvValues = hdRetailCustomerGroup.Value;
string trim = lvValues.Replace(" ", "");

I have an arraylist that holds a subset of names found in my database. I need to write a query to get a count of the people in the arraylist for certain sections i.e. There is a field "City" in my database from the people in the arraylist of names I want to know how many of them live in Chicago, how many live in New York etc.
how I might set up an sql statement to handle this. I think somehow I have to pass the subset of names to sql somehow.
Here is a sample how I am writing my sql in my code
Public Shared Function GetCAData(ByVal employeeName As String) As DataTable
Dim strQuery As String = "SELECT EMPLID, EMPLNME, DISP_TYPE, BEGIN_DTE FROM Corr WHERE (EMPLNME = @name)"
[Code]....
I need a way to create a function using your sql statement to return a datatable object of names and the parameters would be city, and the List of names.
The above example isnt the sql I am looking for its just a skeleton of what the function would look like that I want to create.
So then you would use the function by iterating through all the cities passing in the same set of names each time in the fron end.

I have an idea, but i am not sure how to implement it with code.I have an application where a user can view current bookings for rooms.I have two datagridview controls, the first one shows the rooms and the second shows all my current bookings.What I want to be able to do or more the user, is click on a room and the current bookings for that room (datagridview1) to be shown in (datagridview2).What I think I need to do is apply a filter and a sort in a sub routine, then link my tables with a binding source.
