Forms Data Controls :: Second Dropdown Slected Index Change On Submitclick?
Jan 13, 2011
i have two dropdownlist, second dropdown populates based on value selected in first dropdown.
Parentdropdown is working fine and second dropdown is also popualting correctly. But when i select value from second dropdown and click on submit button it resets to first value i.e though i have chosen 3rd value from dropdown it resets to first value.This happens when autopostback is not thr.
If for the same case ifi do autopostback=true. It chnages to first value automatically . then it odesnot require submitbutton click as well.
In both cases selected index is not getting set for second dropdown.
I have two control page in my aspx page. first one left side "tree view",second one right side " form design".Form design will change based on tree view selected index changed.i have 4 level child node(site, master , slave, space). I have seperate forms to each level of node.

1.1 child node
1.2 child node
i have update "1.2 child node" rename to "1.3 child node"
and reload treeview so it will chage...
how set tree node.selected index = 1.3 child node....

I am developing page for maintaing employee record using Visual Studio 2008, MS SQL server 2005. I am able to fetch and display all the employee information in gridview, the gridview have the dropdown list to display the employee type [ Part Time, Full Time, Permanent , Contract ], in the item template i am having dropdown list. IN the dropdown list i am displaying this. But While saving the record in gridview the droppdown selected index are changed to 0 of other dropdown list.
the user may be change the dropdown value from permanent to contract, or so. but while click on the save button in gridview, all the previous selection are gone, and always showing the first record of dropdown list. I know this is happening because we are doing dropdown list bind on onRowDataBound.

I have a gridview that receives data based on selection from a primary dropdownlist object. Works.
Within the gridview, there is a dropdownlist whose selected index is based on the query from the primary dropdownlist. Works.
Problem.
How do I force the used to change whatever value that the dropdownlist contains after they make their initial selection from the primary dropdownlist; except the default value of "make a selection".
Gridview, contains a checkbox which drives whether a selected row is inserted into the data base. The databind in done using an ObjectDataSource on the presentation page, not in the code behind.

I have gridview control. visit [URL] but when i change page index of this i get error the following error
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
I have a drop down menu that is populated on page load. Below that, I have a gridview that has a select parameter based on that drop down menu's value.

I have one repeater on page which has his own sql data source. I've placed 2 dropdown lists on the page. The repeater has jQuery DataTable plugin. With 2 dropdownlist I wish to change the sql stored procedures so when each will be selected the data in repeater will change. When user select the first there will be only data (users) according to selected item and in the second the same. I wrote 2 simple functions for changing stored procedure of repeater and rebiding it. Everything works but when I try the second one and then the first I always get warning about error "Procedure or function .... has too many arguments specified".
I think that when I select the first one the second function is still called although I don't call it.
I've been strugelling to find a solutions to this, I've searched in the forum and none of the solutions worked for me , I need to highlight the slected item in the menu control which is in a master page. here is my code:the site is running under asp.net 4.0/.net 4.0
