Web Forms :: Select All Dropdownlist?
Feb 4, 2011im working on Visual Studio 2010, and im making a .net web page. The final idea is to use filters by using dropdownlist. By now i have 3 dropdownlist in cascade. The first filters the second and so on. Then by a grid view i display the selected items, right now i need to add an item that allows me to select all the items in the dropdownlist so in the next filters i like i have selected all. My code filters everything but i cant add this item. I only work in asp .net, not in the code behind wich i think is #C if im not wrong... i have to add a button in each dropdown.
I have read others post and the say that i have to add this in the dropdown>> "appenddatabounditems="True" and this sql sentence
WHERE ([PROJID] = CASE WHEN @PROJID= -1 THEN [PROJID] ELSE @PROJID END)
but it doesnt work.

Web Forms :: Programmatically Select Item In DropDownList Based On Text Value
May 7, 2010Here's what I want to accomplish: I have two .aspx pages, the first page with a ddl to select a vendor (SelectVendor.aspx), and one to add a vendor (NewVendor.aspx), if it's not in the first one. If a user adds a new vendor on the NewVendor.aspx page I want the page to automatically redirect back to SelectVendor.aspx and have the ddl automatically select the new vendor that was just added. Here's where I'm at so far: If a vendor is not listed in the ddl on SelectVendor.aspx, a user can click a button to navigate to a page to add a new vendor (NewVendor.aspx). On NewVendor.aspx the user types the name of the new vendor in a textbox and clicks an insert button to add the new vendor, then the page is automatically redirected back to SelectVendor.aspx with the new vendor name added to the QueryString. For example, let's say a user adds a vendor name "Best Vendor": The page is redirected back to SelectVendor.aspx as "SelectVendor.aspx ?vendor=Best Vendor"Now all I need from here is to have the ddl programmatically select the new vendor by the text value in the QueryString.
Here is the code that I'm having trouble with from my Page_Load routine for SelectVendor.aspx:
