What i am trying to do is get a user to change one drop down, which then calls an ajax function which posts to the code behind (vb.net file) then clears and populates another asp dropdown list with the data returned from the function..[code]...
View 2 RepliesI have a dropdownlist that I want to populate with a specific value and specific text. I'm not using a datasource but I am manually making a connection and retrieving data in code. How can I populate this dropdownlist? If I read the data with a datareader and increment an array I only get either the value or the text. This is what I have so far, but it is completely wrong:
//connection string etc goes here
Dbcmd2.CommandText = "select dept,deptname from table"
Dim dr As SqlClient.SqlDataReader[code]....
How can I get this to work without having to create a class object for Department? Is there anyway or should I create the class object?
I am new to Ajax and have a rough idea about Ajax. I am developing a website having a feedback page in which, i want to populate the state/city DropDownList box depending upon the value selected in country DropDownList box.
I have seen some examples downloaded online but they are not working in my application due to many possible reasons, some of them may be the feedback page in my application is a content page, the web application is asp.net 2.0 web application, i don't have any additional ajax tools or scripts installed.give me the solution that should work with asp.net 2.0 web application (in VB.NET) and the feedback page is a content page. I don't want to add custom controls. I want to do it straight away with javascript or vbscript using XMLHTTP object.
After everything is set right with Ajax. What if the browser doesn't support Ajax? What should i do in such case?

I am trying to select a dropdown and populate about 10 textboxes with information. The information is in a database. I know one option would be to write a stored procedure and pass the value of the dropdown box to the sp and then use SqlDataReader to readthe values to populate the textboxes. I am new to VB and was wondering if i should attempt this using LINQ?
View 9 RepliesI have DataGridView control which i populate with some rows from the database the database table which i work with changes a lot so every 30 seconds I re-query the database to check if there is new record or existing record changed or record deleted, I can't clear and re-populate the grid view because people might work with it and they're might doing some changes in some rows.
so if the row was changed i just want to update the changes in the existing row without recreating it, if some row deleted i want to remove it and if a row was added i want to add the new row.

but if the user choose subsector, the subsector value will be appear in the dropdownlist
select subsector: 1) computer
2) utilities
3) consumer
i try to use the hide code but it turns out to be error. i think because of the data overloading.
add optgroup option to dropdown list, The dropdown source is getting from sqlserver.
View 3 RepliesI 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.
