Hi,
My image control is dynamic and the pictures are shown from somewhere from hrddisk and that directory is not a path of virtua directory.
can someone help me out in writing a handler so that whenever the image is shown the request goes to handler and it generates some random path, this is require so that if someone tries to see the property of the image he does not see the Absolute path.
Thanks a lot.

Hi All,
I'm having a problem with linked bound DropDownLists.
I have three DropDowns on my form, 1, 2 & 3, all linked to different ObjectDataSources (ods1 ods2 ods3).
DropDown 2 takes the value of DropDown 1 and uses this as a part of it's query parameter, DropDown 3 takes 2's value and uses this as part of it's query parameter.
The problem I'm having is that when the page first loads, DropDown2 isn't picking up DropDown 1's value and subsequently displays an empty list. Just using these controls, it doesn't seem to be possible to invoke a PostBack event if DropDown 1 contains a single value as neither TextChanged or SelectedIndex are true when the user selects the item.
I'm sure there is a problem with my logic here, so can anyone recommend a good guide on using these controls or offer any advice?
Thanks,
Martin.

After populating the first dropdown you can try passing
DropDownList1.Items(DropDownList1.SelectedIndex).Value
as parameter while filling the second dropdown..

Hi there,
In the second ObjectDataSource you can define a ControlParameter as a SelectParameter, and this paramater is pointed at the first dropdownlist control with the PropertyName is the SelectedValue.
Also, when the dropdownlist has a single item, IMO you may not need to postback the web page.

I think this could be DNS problem. I would say that IP you are trying to resolve has no appropriate name in DNS database. But I never met exception like this and what I did write is only my opinion.

Don't get me wrong here, but it sounds like you need to be learning a whole web technology, not just the small bit to do what you require here?
Have you looked through some of the asp.net tutorials?

i m using two javascript functions in my asp.net project. these are the functions
function valEnb(){
ValidatorEnable(document.getElementById("vldUserID"),true);
ValidatorEnable(document.getElementById("vldPassword"),true);
ValidatorEnable(document.getElementById("vldConfirmPwd"),true);
ValidatorEnable(document.getElementById("vldConfirmPwd1"),true);
ValidatorEnable(document.getElementById("vldFirstName"),true);
ValidatorEnable(document.getElementById("vldFLName"),true);
ValidatorEnable(document.getElementById("vldEmail"),true);
ValidatorEnable(document.getElementById("vldEmail1"),true);
ValidatorEnable(document.getElementById("vldCountry"),true);
ValidatorEnable(document.getElementById("vldCity"),true);
}
function valDis(){
ValidatorEnable(document.getElementById("vldUserID"),true);
ValidatorEnable(document.getElementById("vldPassword"),false);
ValidatorEnable(document.getElementById("vldConfirmPwd"),false);
ValidatorEnable(document.getElementById("vldConfirmPwd1"),false);
ValidatorEnable(document.getElementById("vldFirstName"),false);
ValidatorEnable(document.getElementById("vldFLName"),false);
ValidatorEnable(document.getElementById("vldEmail"),false);
ValidatorEnable(document.getElementById("vldEmail1"),false);
ValidatorEnable(document.getElementById("vldCountry"),false);
ValidatorEnable(document.getElementById("vldCity"),false);
}
these functions are used to enable or disable the validations. i call this functions on page_Load event.
btnCheckID.Attributes.Add("onclick", "valDis();")
btnSubmit.Attributes.Add("onclick", "valEnb();")
but Internet explorer shows an error message - Error : object expected
in FF java console shows like this - Error : ValidatorEnable is not declared

Hi Apurva,
i can't understand your question. i declare those functions(valEnb(),valDis())
in the same aspx file where i call it.
Thanks for your reply

No what i was asking is have you included ValidatorEnable (what i suppose is, this is a user defined function and needs to be included in the page in order to use them.) funtion in your page.

Hi apurva,
I think ValidatorEnable is a system defined function and there is no need for declare it. this code will works fine in local mechine, but when i uploaded it into the sever it shows those errors
Thanks

Hi Thomas,
As far as I know,"ValidatorEnable" is a function defined in the "WebUIValidation.js" file which is present in the C:\Inetpub\wwwroot\aspnet_client\system_web\1_1_4322 folder...
Try copying aspnet_client folder to the root of your website...Your application is probably not able to find the required file.
