Web Forms :: The SelectedValue In The Dependent Dropdown Is Always Empty After Paper Is Loaded?

Feb 22, 2011

There are two dropdowns in my ASP.NET form. The second dropdown is dependent on the first dropdown - the second onedoes not have the item selected in the first one. My problems is that the selectedValue for the second dropdown is always empty after load event. I tried to set the selectedIndex to be 0 before access selectedValue property in the page load event, but it is still empty. What I want is to get the first item of the second dropdown as the default value.

Postback Before Page Fully Loaded Cause Dropdownlist To Have The Wrong SelectedValue?

Oct 18, 2010

We were having occasional reports where the value of a set of DropDownBoxs in a GridView would be reset to the first value item in the list.

We finally tracked it down to a timing issue where a user would click Save before the page finished rendering/loading the data, and we are able to repro it on the production server but not locally because the page loads too quickly.

How would we go about detecting this on the server side to know the data returned is invalid or otherwise stop from setting data that the user didn't set?

AJAX :: Cascading Dropdown Reset SelectedIndex Or Selectedvalue?

Mar 6, 2010

I searched the forum for several days now , but can't find an answer to my problem.

I have 4 Ajax Cascading DropDown named,

ddlCatalogueName > ddlMainGroup > ddlSubGroup > ddlPageNumbers ,

I am passing the values obtained from ddlSubGroup and ddlPageNumbers to a datasource as parameter (Actually to a pageddata ) , on which i create a DataList.

The page is working fine actually but the problem is like the following,</p>

Considering that all dropdown are selected as following :

When i change ddlSubGroup to another one , ddlPageNumbers is populated depending on the number of items divided by 20 ( The datalist is paged by 20 items per time)

then i change the ddlSubGroup(RUBBER PARTS in this example for example to BodyParts , so the dropdown values becomes like :


At this point Body PARTS also has page numbers like 1,2,3,4 etc but, it still remains as 2 , however i need the page number to reset back to 1.

Is there any way to do this , and where should i place the code exactly ( which event ) ?

Cascading Dropdown Empty After Postback?

Sep 15, 2010

A form contains 2 cascading dropdowns. When an item is selected in the first dropdown, jQuery retrieves a list (json) from the server and fills the 2nd dropdown.

The user posts the page to the server, and when the page is returned the dropdown is empty because its not stored in viewstate.

What do you do in this situation? Is this the point where cascading dropdowns using jQuery and trying to make your page a little more stateless gets tedious?

Forms Data Controls :: Dependent GridViews?

Mar 15, 2010

I have this "how to" type of question. I have a page where there are four gridviews. Now these four grids pull data from four different tables. The 1st grid retrieves data from table 1 with a where clause in it's query that comes from a hidden fileld value in the page. Till this things are fine. However, the 2nd grid has a dependency on the 1st grid and the where clause in it's query should be the data selected in grid view1. The 3rd depends on the 2nd one..and so on.
