I have a dorpdownlist in a gridviw template column in asp.net page.
I have applied few checks after dropdown_SelectedIndexChanged event and if the new value doesn't meet the needs then it should get that previous value that it had.
I have a parameter page which contains a hyperlink. This hyperlink opens a new window when clicked. I am passing the value of the selection made in the listbox in the new window to the previous page via session. Now, once, i again click the hyperlink in that session, i want to show the previous selection made on that hyperlink page.
View 12 RepliesHow would I get the previous item on DropDownList before OnSelectedIndexChanged fires the event?
I had a DropDownList that has names as its items ("John", "Mark"). By default the SelectedIndex is "John". Upon changing its index and selecting "Mark" the event OnSelectedIndexChanged will be triggered. When I use ddlName.SelectedIndex it will return only the index for "Mark" which I want to get is the index of "John".

View 1 Repliesi am currently developing an asp.net project. there is a previous, next, and cancel button that the user can utilize, but the problem is that everything is broken into controls so that if they hit the browser's back button it will reset everything and take them to the very beginning. i would like to capture the onbeforeunload event and trigger the previous button click event (i.e. treating navigation like clicking the previous button).
View 6 RepliesI'm using a wizard control with 4 steps, when I use the previous button to navigate back to the previous step the page reloads but at the bottom of the page.Instead of showning the whole of the page, the user views the footer of the site and the previous button and next button.I'm sure there is a very simple answer to this but I just can't figure out how to get the page to reload to the top.

View 2 RepliesI've tried many different ways to try to get the selectedIndexChange to work for my dropdownlist. It doesn't seem to work, when I debug, I can see that the page is doing a PostBack but the method that suppose to be taking care of the select index change doesn't seems to be fired. I notice that there is no "handles" in many post so I was just wondering why it doesn't have it?On postBack I didn't rebuild the list so the selectedIndexChange value shouldn't reset to 0.Sub ddlAccess_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) ''handles ......?"

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 want to execute code written in a dropdown selectedindexchanged event from some another user defined function.
For this i m writing:
ddlMyDropDown1_SelectedIndexChanged(sender, e);
It works when use it in page_load (means the code in ddlMyDropDown1_SelectedIndexChanged is executed) but when i write the same line in another function it gives error "The name sender doesnot exists in current context".
I ask for a date, on OnTextChanged event i bind data with a SqlDataSource to a dropdownlist and also bind data to a repeater passing the dropdownlist SelectedIndex (i use SqlDataSource too and ControlParameter to link the dropdownlist and the repeater) On my repeater during the ItemDataBound event i create dynamic dropdownlist controls, my code is :
[Code]....
[Code]....
On the Page_load event of my page i bind the data & recreate the control :
[Code]....
Everything works fine, datas are bound and SelectedIndexes are restore on every postback.
The probem occurs when user change different dropdownlists, if he choose to change the 1st dropdownlist the event is fire (normal), after if he modifies another dropdownlist the event is fire twice, if he modifies a 3rd time the event is fire 3 time etc...

View 8 RepliesI am having a gridview with dropdownlist and textbox controls.
I am generating a value in the textbox2 depending on the textbox1 value using the javascript in every row of gridview. In onblur() function of textbox2, I am disabling the textbox2.
Before textboxes, I am having dropdownlist's in every row of gridview. when I disable the textbox2 in the first row and select the value of dropdownlist in the second row, the value of textbox2 in first row is not visible.
I tried by using the viewstate but I am unable to retain the value.
I have a formview tied to a gridview. The formview shows the data for the row selected in the gridview. The formview is invisible by default , default mode is readonly and becomes visible only on Selecting a row in the gridview. I make it visible in the SelectedIndexchanged event of the gridview. There are Insert and update buttons present outside the formview which perform the insert and update using code-behind. The code is below.
AFter an insert or update, the formview makes invisible again. I want to show the formview with the newly inserted or updated row in Read-only mode. How do I do this?

I have 3 gridviews on a page in a parent child relationship. i.e, when Grid1 is selected, any child rows will be shown in grid2. When a row is selected on grid 2 , any child rows will be shown in grid 3.
I have a single formview used for editing and inserting tied to all the 3 gridviews as they are of the same table structure.
The issue is whenever an insert or update happens on the formview, all the selection is lost. How do I retain the selection on the appropriate gridviews and also refresh only the gridview which caused the change?
For eg) when I select a row in grid 1, the child row shows up in Grid 2 . When I selected the row in Grid 2 for edit, the data appears in the formview. After I update the data in formview, when the page gets refreshed, the row in Grid2 does not remain selected. How do I retain the selection?
