View 3 RepliesUsing VS2008, been working fine until recently when the build errors, which usually allow you to right click and navigate direct to the error in question, have this "Go To Location" feature disabled.
Go To Definition still works from within the main editor but this build error thing is really annoying. If I get something saying "semi-colon missing" I have to go back and review all the code I've just written to spot the missing semi colon. How do I re-enable this feature (even though I don't remember disabling it).
i am using ajax combobox.it works fine for fetching and updating data.but when backspace or delete is press the it gives error :
Message: 'this._optionListItems[...].text' is null or not an object

Code: 0
I'm employing a solution similar to the answer of OnclientClick and OnClick is not working at the same time ?
How this currently works is that a file is generated and returned to the client, however after the file is returned the button should become active again.
so the response contains the file. But the button does not reactivate.
I have a problem with CascadingDropDown... I have two related comboboxes, where the second is a slave of the first (e.g. country the first, cities the second). What I want is that if I select one country from combobox 1 then the second must be "filtered" by that selection (it should display all the cities inside the selected country, and the actual CascadingDropDown implementation is OK), but if I leave the combobox 1 in the default option (e.g. "Please select a country") I want the second to display all the cities I have in the database. The problem is that when selecting default option for combobox 1 the second combobox is disabled and a postback to my webservice never occurs.

I have a webform with textbox and button,i want to disable the button when nothing is entered into textbox and if something is entered the button must be enabled.How to do it without javascript?
View 14 RepliesI'm working on an ASP.NET application. Currently when the user clicks "Save" on an item, we disable the Save button, change its text to "Saving..." and so on. This works fine, because the button causes a postback which results in a new page being loaded, on which the Save button is no longer disabled.
We now want to apply this to other actions: Publish (not much different from Save), Import (again, much like Save, but based on data the user has uploaded in a previous step), Export (downloads an XML file to the user) etc.
Export is causing me problems - the button stays disabled. I think this is because the server sends back an XML file rather than a new web page, and so the browser just displays the same page.
The server-side code is along the lines of
Response.Clear();
Response.BufferOutput = true;
Response.ContentType = "text/xml";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + whatever);
[push file contents into Response.OutputStream]
Response.End();
a way of making the server send a fresh page back in the response as well as the XML, thus re-enablnig the button in the same manner that the other pages do, ora way of getting the browser/JS to re-enable the button once the file has been sent.

I have a couple of dropdownlists and a button.when a user selects an item in the 1st dropdownlist,the 2nd dropdown is programmatically bound to a set of items(using an ajax request) depending on the value selected in the 1st dropdown.Then the user will have the ability to choose an item from the 2nd dropdown and click on the button,which performs some server side opeartions and returns the results.
But if the user tries to click on the button before the 2nd dropdown list is populated,user will receive an exception message.Instead of that I would like to prevent the user from clicking the button before the ajax request is completed to populate the 2nd dropdown.I tried using Button1.Enabled=false in the selectedvaluechanged event of 1st dropdown,which does n't seem to work.

BtnAdd is the (aspx button runat server) control I want to disable.
While compiling it does not shows error.But while runtime It throws error saying btnAddis null.
so i have a lightbox in which pops up an aspx page with textboxes and two buttons (submit - disabled and cancel - enabled). I wanted to enable my submit button ontextchange. it works fine when opened separately (not as a lightbox) but when i let it run normally with the lightbox function everytime ontextchange gets triggered the whole page refreshes disabling the lightbox.
<asp:TextBox ID="textBox1" runat="server" OnTextChanged="OnTextChanged_AttributesEdited" autopostback="true">
protected void OnTextChanged_AttributesEdited(object sender, EventArgs e)
{
btnSubmit.Enabled = true;
}
now if i take out the "autopostback=true" it then will not trigger the the ontextchanged. was wondering if is it better if javascript will be the way to go for enabling the button or is there a way where i can prevent the postback when ontextchanged is triggered?
var elem = document.getElementById('<%=imageButton1.ClientID %>');
elem.setAttribute('enabled', 'true');
elem.setAttribute('enabled') = 'true';
