Hi All
I have an ASP.Net TreeView with checkboxes, so I am looking for a code that will UNCHECK all checked checkboxes on a click of a button.
Thank you in advanced.

I'm using a CAPTCHA image generator from Code Project and would like to wrap this in to a web control.
So I was wondering what's the best way to display a dynamic image from a memorystream? Currently I'm setting the img src to a handler which works fine. But the handler needs to be a servable page and can't be wrapped in to a control dll. I'd prefer not to write the image to a temp directory. Is there an alternative or a nifty trick like putting the handler in as a resource in the dll?

Ehhh, I'm already using a httphandler (ashx). That's the problem, you can't wrap an ashx page in a web control dll. It has to be a servable page on the actual website.
The point of my question is how to achieve this functionality within a seperate web control dll.

Hi,
I have a page that is pretty complex, i.e. it has a table with lots of controls, everything generated from data in a database. Each row contains among others a DropDownList, and when certain items are selected in that dropdownlist, the rest of that row should be disabled. The rest of that row contains text boxes, drop down lists, and a few validators. The number of controls is dynamic.
What would be the best way to accomplish this? What I've got so far is:
- a onChange attribute for the dropdownlist,
- a javascript function which gets called in the onChange event handler
- this function correctly determines if I should enable or disable the rest of the row
- ... and then calls getElementsByName to get an array of elements that should be enabled/disabled.
But this is where I stop, since getElementsByName doesn't return anything. If I specify a name attribute for the controls that should be enabled/disabled, it won't render to the page since ASP.NET will override my setting with the id of the control. I could probably create a subclass of TextBox and DropDownList, and modify their RenderAttributes( ) function, I just haven't gotten to it yet. Is there an easier way?
Even if I succeed with that, I still have the problem of disabling the validators for the controls that should be disabled. Is there some easy way to accomplish that? I found http://www.codeproject.com/useritems/ASPNET_Validation_Tamed.asp[^] which talks about similar solution, but am I missing something completely obvious? I'm aware of the fact that I could set the AutoPostBack property of the DropDownLists to true, and handle the change events server side, but I would rather do it client side just to minimize server load. But then again, if I must use server side I probably will.
So anyway, any help or hints whatsoever would be highly appreciated.
Regards,
Daníel

Sorry. I forget your last post...
Steps:
1. Add one button and one Literal control.
2. In Button_click
2.1. Get the completed embed object tag from database depend on the parameter
2.2. Set the string to Literal1.Text (e.g. Literal1.Text = @" EMBEDDED TAG FROM DATABASE";)
That's all.. Let me know if you are not clear

Yeah. You need to assign the object tag to Literal.... then, the movie player will be shown in your page. So, the user can click to play the movie...

Hi,

Thanks,

Why don't you set the navigateURL while populating the Datagrid? Any different??
|
|
|
|

i need to set the url with 3 parameters(Querystring) whose value need to be taken from datasource.
This three parameter value depends on the row in which hyperlink is clicked.
Now my doubt is how should i frame the navigateurl with the Eval() method.
Thanks,
Srikanth

I am having a serious issue. I have searched for and tried every solution I could find. This is the error I am currently getting.
e current identity ("Computer Name"\ASPNET) does not have write access to 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files'.
ASP .NET actually has full control on this folder. Any suggestions? I also got an error involving the IIS metabase once. I have reinstalled everything and even repaired the .NET Framework 2.0. I then ran ASPNET_REGIIS -i and - ga ASPNET. No go on anything so far. PLEASE HELP!

As long as this is a development machine only you can use "identity impersonate" within your web.config file to let ASP.NET assume an admin role, which should get you around this problem. *** Just be sure to remove this when you want to deploy on public server. ***
If your machine's admin login is
username: abc
password: xyz
add the folowing line within the <system.web> block of the application's web.config file:
<identity impersonate="true" userName="abc" password="xyz" />
