View 2 RepliesI can change the language of my site using a drop down list put I cant do it with buttons.
I have a button for each language. The user clicks on a button to choose their language.
The problem is that the "button click" code happens after the "Initialize Culture" Code.
So the language only changes after a page refresh.
I don't want to use parameters e.i.
[URL]
I want to change the language through code.
i have a dropdownlist and a textbox in a repeater i need to enable/disable the textbox depending on what was selected in the repeater.

i have got grid view with 4 coloums which contains 2 dropdown list. n i have 2 drop down list out side the gridview .
i want to change the index of the 1st coloum dropdown list inside the gridview when changing the drop down list index outside using javascript
similarly the when the 2nd dropdown list(out side ) index change the 2nd coloumn dropdown list in gridview should change.
In short the outside placed dropdown list should act as master dropdown list.
if a asp.net web site project is created using code behind as C# language then the Page and its controls events are not shown in the DropDown at top of the editable area in Visual Studio.But contrary to this if code behind is VB.NET then in the DropDown all Page events and its controls events are shown.
Is the same possible with code behind as C# language ?
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.

View 3 RepliesWe are developing our application on a 64 bit server. We are using a dropdownlist to filter and display departments in a htmltable(hide and show rows) on every selectedindexchanged event.
The issue is it is firing properly for the first time, but it is not doing a post back there after. We have even given autopostback=true. We are using AJAX for hiding and showing the rows of the htmltable.
I am having a label to show success message during the successfully save.
I am having a drop down with the name "Technology".
During on selected index change event of the drop down, i am binding another drop down with the name "Resources".
When the Button is clicked, i am showing the "success message" and on click event of the drop down, i am clearing the message by using the java script.
function ClearErrorMessage() {
document.getElementById('ctl00_ContentPlaceHolder1_lblMessage').innerHTML = '';
}
But when i change the drop down, the message gets reappeared.
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 details view control which contains a dropdown list.
I would like to update a row in the DV based on when the selected index change event occurs in another row of the
So far I know that 1) Place code in detailsview1.rowupdating event .
2) Make a row copy, not sure about the syntax here
Dim
aRow As DetailsViewRow =
Me.DetailsView1.Rows(DetailsView1.Rows.Item(?))
3) Find my DDL
Dim aDDL as dropdownlist = CType(aDDL.cells(?).Findcontrol("Dropdownlist3"0, dropdownlist)
If aDLL.selected IndexChanged then
Dim aTextbox as textbox = Ctype(detaislview.cells(?).findcontrol("Textbox6", textbox6)
aTextbox.text = now()
Here is the thing. I have an aspx page with NO master page. I have two resource files with the same name (and specifying the language) in the App_LocalResources folder. If I do something like text="<%$ Resources:lblUser %> works fine. What I do to test it is change the browser's selected language.
But, if I do the same in a MasterPage or in a Page that is inside a MasterPage... when changing the Browser's language and refreshing... I'm still getting the default language...
I've been reading some threads about this but the situation was a little bit different.
