Now here is part of my dilemma.  I'm entered other data on the form, so if I postback I need some way of knowing that the postback is just for the purpose of filling the secont dropdownlist.  In addition everytime that first DDL is change...

Custom paging and DataGrid's PageSize value change through dropdownlist control
I'm implementing custom paging for a datagrid through an asp.net dropdownlist control that postback the new pagesize. It looks like: protected void ddlRecordsPerPage_OnSelectedIndexChanged(object sender, EventArgs e) {             this.dgLocations.PageSize = Int32.Parse(this.ddlRecordsPerPage.SelectedItem.Value); } But upon the page reloading, the old pagesize is what loads on not the new one.  Only when I do a postback again does the new pagesize take effect. I know many would recommend that I do something like BindData() ...

dropdownlist
i have created a dropdown list that is populated from a sqlserver datasource. i have a separate sql command which uses the dropdownlist.selected value as a parameter and returns the command value to a label.  it mostly works fine but with one problem. when the page loads, the label value is null, because it doesn't seem to treat the dropdownlist default value as a selected value. when i use the dropdownlist to select a value, this is fine and the label begins to display the expected value. is there anyway I can make the default value when the page is loaded act like a manual...

Getting DropDownlist's DataTextValue Selected Value Given the SelectedValue and/or Selected Item
In the vb.net codebehind, I need to extract something from the Text (displayed) value of dropdownlist's selected item and I have  the SelectedValuand and SelectedItem in hand. How can I do this?  FindControl? Item? row?   Thanks. Well, its easier than you might think. SelectedItem has a "text" property. Thats the selected text right there :)  If you need the Text of the selection, then you have to use the SelectedItem.Text property.  If you want the value (not the displayed text) the you can directly use the SelectedValue. dim sText as String = dropdown...

Dropdownlist on website
When I access an application written in asp.net 2.0 on my pc (uses XP) and on a laptop (using Vista), I can type into the dropdownlist to search for a record.  But other pc's (using XP) do not allow the user type to do a search.  Only the first letter of the word or the drop down are available to do a search.   Does anyone know why it would work with some pc's but not on others? I think this behaviour is in IE 7, check to see what versions of IE the PC's have that done work.-------------------------------------------------------...

Coding DropDownList's Selected Value and ArgumentOutOfRangeException
I have a SQLDataSource that feeds a table of account names and numbers to a DropDownList which in turn feeds the account number to a ListView to display all related orders.  The dropdownlist has an autopostback to update the ListView - and that works fine. I then have Page_Load checking to see if there is a QuerySting value that can be parsed into an Int32 and passed to the DropDownList as the SelectedValue.  If the account number exists in the query that the SqlDataSource provides, then it properly selects the correct row.  But as a test, I changed the QueryString value to a...
