You cant do that ...
Even ASP.NET cant do this, thus it cant retain its value during postbacks..
Sorry.. You need to store it in server as soon as you find it in server. And then show the message, file uploaded successfully.. .or so... 
|
|
|
|
|
still confusing.. How to store(session or any string variable) and assign to to fileupload control...
|
|
|
|
|
As I already told you, even if you set the value of a FileUpload control, it cant assign the appropriate file pointer to the browser.
So dont try to do this, rather when user choose the file, upload to the server immediately and work from the file placed in the server.

I m making role based security with forms authentication in that, to make the role authentication work for forms authentication i modify web.config file like this:-
<configuration>
<system.web>
<authentication mode="Forms">
<forms name="MYWEBAPP.ASPXAUTH"
loginUrl="login.aspx"
protection="All"
path="/"/>
</authentication>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
<location path="administrators">
<system.web>
<authorization>
<!-- Order and case are important below -->
<allow roles="Administrator"/>
<deny users="*"/>
</authorization>
</system.web>
</location>
<location path="users">
<system.web>
<authorization>
<!-- Order and case are important below -->
<allow roles="User"/>
<deny users="*"/>
</authorization>
</system.web>
</location>
<configSections>
.
.
.
.
.
.
.
</configuration>
and with this coding i m getting this error:
only one element allowed per config file and if present must be the first child of the root element.
plz help me with this error

I also faced this problem in the beginning..! this is due to presence of other config section..!
Check your config section there will be 2 config sections after debugging .!
keep one in comments or delete it..!

Even I'm not sure! When I once asked this to one of the MCTs that I know, he said its better to use "String" for declaring string type variables, but he wasn't able to give me any reasons either! But, I rarely use String/string type variables. I use StringBuilder for all string manipulations.

StringBuilder is usefull when you are doing a large string ( inside loops ) operation. For Small operation its always preferable use string not stringBuilder.

I just use StringBuilder when I know that a specified string is going to be modified more than 2 times after the original assignment, otherwise I use general String/string. I guess its just general preference!

Apart from having that sort of coding guidelines, I see no reason of doing that.

Hi
String is a .net data type
string is a C# data type
I think that there is no difference.
My Reason:
right click on the string and select "Go To Definition" from string's context menu
it refers to String definition

string is an Alias for System.String. IL version of both string and String is System.String. So there is no difference between them.

Your web.config is not pasted properly. Please check "Do not interpret HTML tags (good for code snippets)" before post config code.

Hi,
I am facing a problem with the validator. Required field validator is not displaying error message for the control dropdown. am binding dropdown with the datatable. and set the initial value property as "select product" in the required field validatior.If i didnot select any thing from ddl and click button its not showing any error message...below is my code.
// Binding the dropdonwn with the data table
DataTable datatable = GetDataFromDB("SP_GetProducts", "All");
DropDownList2.DataSource = datatable;
DropDownList2.DataTextField = "Product Name";
DropDownList2.DataValueField = "Product ID";
DropDownList2.DataBind();
DropDownList2.Items.Insert(0, "Select Product");
<asp:DropDownList ID="DropDownList2" runat="server" AutoPostBack="True"
Height="22px" Width="234px">
</asp:DropDownList>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server"
ControlToValidate="DropDownList2" Display="None"
ErrorMessage="Please select the product" InitialValue="Select Product" ValidationGroup="Calculation"
>*</asp:RequiredFieldValidator>
<asp:Button ID="Button1" runat="server" Text="Calculate" Height="22px"
onclick="Button1_Click" ValidationGroup="Calculation" />
can any one tell me where I was wrong...
|
|
|
|
|
Validator controls are case sensitive! So, select product and Select Product are different!
HTH!!
|
|
|
|
|
yes I gave the same... pls check in the code once again.... but button_click event is not firing if we don't select anything from ddl... only the issue is its not displaying error message....
|
|
|
|
|
I'm sorry, I just checked the text and the DDL definition! My bad!!
I think you should change the Display property on the validation control from Display="None" to Display="Dynamic".
