In addition to the other suggestions, buy a basic book and work through it before you start trying to write any code that you expect to work properly. It's clear you have no grasp of the basics. We can't really help you there.

I want to put one button just near the right side of the screen, how to do?
thanks.

Use absolute positioning and place it where you'd like. Otherwise, determine the screen size with JavaScript and position it appropriately. Don't forget to handle the resize event.

You can use div and in the style attribute use absolute positioning with y axis and x axis.

Hi,
1)I am having one dropdownlist,one textbox and one submit button shown below
<asp:dropdownlist autopostback="true" cssclass="textboxGQ_New" width="200px" id="drp_Category" runat="server" onselectedindexchanged="drp_Category_SelectedIndexChanged">
<asp:listitem value="">Select Category
<asp:listitem value="Samp1">Sample1
<asp:listitem value="Samp2">Sample2
<asp:listitem value="Samp3">Sample3
<asp:listitem value="Samp4">Sample3
2)My isssue is If i select Sample1 or Sample3 from the dropdownlist the text box should fire requiredfield validation i.e it has to show an alert as plz enter text in the textbox.
3)If i select Sample2 or Sample3 from the dropdownlist the text box should not fire requiredfield validation i.e it should not fire any validation and should accept null value while submit button is clicked
4)plz provide the sample code for the above issue..i want server-side code..i don't want Using JavaScript funtions....

Well, if you want server side code, you don't even need a 'validator', unless you're using that overall framework. And the code is so trivial, that I don't see why you'd have trouble at least trying to write it, and posting a more specific question if you get stuck.

Hello,
I want submit button to fetch different query results from the database. So I have implemented which query to execute inside the SubmitButton_Click function/method. But it's not working as I have desired....it's fetching one query every time.
To give you a brief idea, in my .aspx I have 2 dropdown lists (1 to select which query to run and another one to select which patient number should I pull from the DB), 1 text box which contains date field. I have kinda found what's causing the problem....but don't know how to solve it. Somehow from the drop down list "ANY" is selected all the times.....no matter what I select from the second dropdown list. Any suggestion would be really helpful.
The code is as follows:

I'm not a C# guy, but it sure seems like you call getMLNO on every page_load which then adds in the "Any" item into the dropdownlist which overrides what the user selected. Put that in a If Not Ispostback then (C# equivalent for you) you should be all set.
|
|
|
|

I don't know how to thank you enough!  all these times I am wondering why this is happening!! But I understood that something is wrong with the post back condition and the way I am calling getMLNO() cause every time I refresh the page or hit submit the MLNO dropdown list was getting refreshed as well and thus selecting ANY every time....

My pages worked fine, when they were located on the root of my project. When I moved them to folders, in preparation of doing roles/permissions, I had some issues that I worked through.
Dropdownlists with AutoPostBack = "False" on the page work fine. But, I cannot seem to get past an issue with a dropdownlist that does a postback. I am getting an error: Sys.Webforms.PageRequestManagerServerErrorException. The status code returned from the server was: 404.
I think the problem is related to AutoPostBack and UpdatePanel, but I don't know how to fix it. If someone could point me in the right direction, I would appreciate the assistance.

I'm hoping someone has a simple example they can point me to. I am trying to get a web page to be able to use a DLL for local printing on some administrators pages. All appears to be working fine until I have the DLL try to access the same MS SQL database that the rest of the website is accessing. Then, I get the SQL Permission error.
I've tried the assert method to get around this, but no luck. I've been trying to create the DLL as a strongly named assembly and get it installed in the GAC on the administrators' computers, but my page can no longer access the assembly after it is strongly named. I suspect I am missing something simple in the object tag on the page, but cannot seem to find what that is.
Currently, I am using:
<object id="PrintTag" height="31" width="177" classid="bin/<dllname>.dll#<classname>">
on the page. This works if the dll is not strongly named and my calling function within the Javascript works, except for the SQL Permission error. When I strongly name the dll and try it, I get an undefined error. Makes sense that the <classname> has changed, but I can't seem to find what it has been changed to to call.
Any thoughts?
