If your drop down is data bound and you bind to the data source every time, that will reset the selected index. Use !IsPostback to only do it the first time.

OK, I truly hang my head in shame, how could I miss something so obvious! Think I couldn't see the wood for the trees, so to speak!
Thanks Christian, worked a treat and thanks for such a prompt response

No-one knows. There is no chart component build into ASP.NET, so we'd need to know what component you're using, and then we'll probably tell you to ask the people who wrote it.

Hi,
I m having following problem while dedugging the site having gridview.......
Cannot open database "Test" requested by the login. The login failed.
Login failed for user 'PC6\ASPNET'.
|
|
|
|
|
Well, a good place to start might be to make sure that the user has permissions to access the databse, run stored procedures, etc.

this code keeps coming up on my first page.
Compilation Error

Hi all,
I started with an intranet site for our company, so I'm using windows authentication for the site access. I had a look at the configuration tool provided in Visual Studio 2005 and added the roles of administrator, editor and browser.
The idea is that the users will default to browsers role, so they will only be able to view the intranet site, but I want to assign different access levels for the managers of the departments, that is why I have administrator and editor. So the managers of the departments will be able to edit the content of their departments but not of the other departments, and the rest of the department will only have browse capability.
So my question is how do I assign those specific users those roles?
Thanks in advance

You have to add this panel control into ASP.NET Ajax Update Panel.

Use Javascript like something below.
Assuming you need to update a button with id "TestButton"
document.getElementById("TestButton").Value = "TestData";
If you require it to be more complex operation you will heva to use the XMLHttp object to retrieve value and use JS to update the control.
Thank you

we want to load images to our web page at the time when we scroll down . because there may be 100-1000
images .so loading all the images all together id inefficient.
thanks

Ajax to the rescue. You've to track the page scroll (or control scroll) event and load the picture if the scroll value exceeds a given height.

Hi,
Hope every one is fine. I am developing a website using ASP.NET 1.1. My site is working fine in Internet Explorer but when i run it on Firefox the alignment of controls changes and site looks deshaped...further more if i run it on NetScape only the login page is displayed and when i login every thing goes blank, no page or control is displayed.
Kindly tell me what is the reason of this problem and how to overcome it? Somebody told me that there is a option in properties of project which enables site to be displayed same on every browser, can any one tell me where is that option?
Thanks in advance,
Regards,
Affan Ahmad Toor

Basically, the different browsers render different CSS differently. You need to work through each issue in your site and find ways to lay it out that work with all browsers. Welcome to hell, sorry.

How to reorder the columns of a databound gridView in run time
|
|
|
|
|
There is nothing built in to do that, you'd have to do it with javascript. Of course, a gridview is a server side construct, it's just spitting out a table on the client end.

I have created a textbox on button click event :
<code>
protected void btnCreateTextBox_Click(object sender, EventArgs e)
{
TextBox txtDynamic = new TextBox();
txtDynamic.ID = "txtDynamic";
pnlContainer.Controls.Add(txtDynamic);
}
</code>
and when the page loads, i click on the button to load the textbox at runtime, it works fine.
The problem in in fetching the value of the textbox when the user clicks on the "save" button.
I am trying this, but it doesnt works. Since after the postback, there is NO existence of the runtime textbox.
<code>
protected void btnSaveTextBox_Click(object sender, EventArgs e)
{
Response.Write(GetDynamicTextValue());
}
private string GetDynamicTextValue()
{
foreach (Control ctrl in pnlContainer.Controls)
{
if (ctrl.GetType() == typeof(TextBox))
{
return ((TextBox)ctrl).Text;
}
}
return string.Empty;
}
</code>
Here is body of my aspx page
<code>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID=btnCreateTextBox runat=server Text=Create OnClick="btnCreateTextBox_Click" />
<asp:Panel ID=pnlContainer runat=server></asp:Panel>
<asp:Button ID=btnSaveTextBox runat=server Text=Save OnClick="btnSaveTextBox_Click" />
</div>
</form>
</body>
I understand the problem is related to page life cycle, but am not being able to resolve it.
Could somebody please explain me the same OR write the "GetDynamicTextValue()" method for me.
Any help/referrence/discussion will be of real help. Am really stucked into an application that needs this utility.
Thanks a lot for reading.

Thanks a lot for the reply.
I understand what the code is doing is, its loading the textbox again in each page load so as to keep its existence thru the round trips. The solution is perfectly fine but i didnt wanted that to happen.
I dont want to reload the textbox once the "save" button is clicked.
To be pertinent, I want to know is there a way to "manuallly" catch the values stored in the PostBackData... i know abt _doPostback event, but then how to write a "generic" method which can keep track on the values of a desired control. [ ]

If you know exactly what to search for, why don't you? There are a lot of excellent tutorials and examples available already.
Search[^]
The answer to this kind of questions is better found in the material that is already available. If you have some more specific questions, those are better suited to be asked in a forum.
