I have started learning ASP.NET. I am Trying to filter GRIDVIEW values on basis of dropdown selection.I am working trying to do this with AJAX.
When a user selects any value from the drop down..suppose an employe ID.the gridview is filled with data according to that empID.
how Can I do that.
I'm having a problem with using a dropdown to filter the contents of another drop down. The basic idea is:
Dropdown 1 = CountryList (Column1)
Dropdown 2 = StateList (Column2)
I read the contents of a CSV file and populate the gridview. The user then visually verifies that the data is valid and proceeds to upload to the database. To do some testing, i have intentionally changed spellings of country names so they DO NOT match the countrylist which the grid view then flags with a different background indicating bad data. The user then edits the gridview. The Country and state columns then show a drop down control populated with the country list and filtered states list based on countryID.
Here's the ASP.NET ASPX Source for the section of code that is dealing with the gridview
[Code]....
Here's the section of VB Code behind that deals with handling the "RowEditing", specifically the binding of the dropdowns
[Code]....
The proglem is that these dropdowns are ment to easily fix minor errors in data. When i intentionally changed the spelling of "Canada" to Canadaa", this has no corresponding CountryID in the table and the ddlEdtStateID Dropdown's datasource filter does not work. I tried setting the datasource to nothing if a valid CountryID was not there and then i tried to use the SelectedIndexChanged event for the ddlEditCountryID to programmatically set the datasourceID for ddlEditStateID but when i try using CType(FindControl("ddlEdtStateID"), DropDownList) to set the DataSourceID, it does not find the control.
If the Country does not exist, then i just want the stateslist dropdown to say "select a country" but when a valid country is selected, it should display the filtered list for that countryID. Right now, if bad data is entered for the country, then the program crashes when it tries to populate the state drop down. I want it to just say, select a country when the countryID is not valid.
I Have the gridview control with 2 dropdown list and 2 text boxes,When the textbox chnaged event happen 1 row will create and the dropdown back to initial values( its not retaining the selected values),I am binding the control after text changed method,Is there any properties needs to be set or any other way we can retain the values in postbacks?
View 4 RepliesI'm trying to create a page with multiple fields to be used as parameters for filtering a GridView. I'm using a combination of two asp:dropdown lists and two check boxes. When I select a value in one ddl, I want to clear the value in the other ddl. I was trying to use the event "onTextChanged" but that doesn't seem to fire off on the client side and I cannot seem to find any event for an asp:ddl or asp:checkbox or asp:radio button that fires off on the client side.
Are there events, like onClientClick for asp:button, that fire on the client side for these controls when a selected value is changed or when the user clicks on them? or do I need to use html controls instead?

View 2 Replieshow to implement a filter feature like this? What Ajax or JQuery controls can be used for this (if any)?
Here is an example of how the UI might look like:
See the Exchange Management Console image:
[URL]
Here is the spec:
The ASP.NET page has a "Filter" component and a "Apply Filter" button. The "Filter" component consists of 4 UI controls as below:
1. A dropdown list with prepopulated values like "Name", "Department", "Building", "Email Address".
2. A dropdown list with four operators - "Equal", "Not Equal", "Like", and "Not Like"
3. This is a dynamic control. It could be a textbox or a dropdown list. If the user chooses "Name" from the first UI control, the third UI control will become a Textbox. If the user chooses "Department" from the first UI control, the third UI control will become a dropdown list with all departments within this company pre-populated.
4. A button with AND expression. If the user clicks this button, one more Filter component will be created.
One possible user case is like this:
ASP.NET: when the page is loaded, it displays one Filter component (3 UI controls and a AND button), a "Apply Filter" button, and an empty "Filter Result" data grid.
I have a listview that is displaying records currently based on a dropdown.. works great.. now, within those results returned, i would like to filter down some more.. How can i add a dropdownlist to the page that is populated with data from the listview(only 1 field would be used to create the list ) and if you chose to filter by that drop down, then the listview is revised to display only records with the selected value.
Example..
Currently you pick from a drop down.. Report#1, Report#2 or Report#3 Say report#1 returns 100 records.. and the field im going to be filtering on is my "Vendor" field.. so once my listview displays my results, a dropdownlist is populated with all the vendors that were returned with the query.. could just be a few..
Now you are sitting there paging thru all the records.. and realize you really just need to see out of the 100 records, records that belong to Vendor#3, so you pick #3 from the drop downlist and the procedure is called again now filtering on that vendor..
I want to filter the table in my Listview (mvc2) using values from a dropdownlist shown at the top of the page. The values in the list are hard coded. Next to the dropdownlist I got a "Filter" button that calls the filter method on the controller / How can I pass the selected value from the list to the controller? for now I'm using a classic asp:dropdownlist

View 5 RepliesI have an SqlDataSource, which is filtered by two RadioButtonLists. The markup is as follows:
[Code]....
In my code-behind I add the filterexpression when the radiobuttonlists are changed
[Code]....
My problem is that while it works fine when changing the RadioButtonListProducts the filtering works nicely, there is a problem with the RadioButtonListStatus, that filters on the Boolean column, 'Godkendt'. It works nicely if its set to 'Alle' (No filtering on that parameter) but when set to anything else, no records are shown. I suppose the problem is in the filterexpression
