Which label? Label2 (look, never use auto-generated names; always rename to something semantic; this is even the violation of good Microsoft naming conventions)? But you assigned an immediate string constant to its text. What do you need to have, an empty string? Then assign it, perhaps depending on some condition. What's the problem?
The question suggests you don't know how Web works, HTTP request/response, etc.

Since you have the label inside the repeater control, depending on your requirement, during page post back find control and clear it or change the repeater binding to Nothing.

But if i set this then when i'll click on button then label2 will not show message
Label2.text="Stock Detail(s) Deleted";

Can you make clear which label you want to clear ?

Surendra0x2 10-Oct-12 5:01am

label2 sir you can find on above code

MT_ 10-Oct-12 5:03am

So what is the problem you want to loose the value label2 and you are loosing it by setting as I said. If you want reset to "Stock Details(s) Deleted". set Label2.Text ="Stock Details(s) Deleted". Or even better set Text value in properties in design mode.

i want on Button Click, Label2 will appear and after when i refresh the page i want to clear the label's value

Surendra0x2 10-Oct-12 5:12am

on ctrl+R i want to clear Label's value

MT_ 10-Oct-12 5:13am

Yes Surendra. Set the value on Page_Load to whatever you want and that will be shown when you refresh the page. Do you have any problem there ? Probably you can check If(!IsPostBack()) before setting so it does not clear on button click as well.

Solution 3

<asp:Label ID="lblMsg" runat="server" Text="Stock Detail(s) Deleted" EnableViewState="false" visible="false"></asp:Label>

This is what you are looking for. Please Note

EnableViewState="false"

dheeraj9457 has already mentioned this.I just felt i should clarify.

Hope it helps.

Sir i want to clear label when page is refreshed by user
first time when i'll click on button then it will show label but when at the same time if i refresh the page then i want to clear the label's value

TheCoolCoder 10-Oct-12 5:11am

See if you are talking about a refresh just after a button click normally if you hit f5 or refresh from browser you will be prompted 'if you want to resubmit data to server', if you click yes then the previous button click will be re-done, in that case your code label2.visible=true will execute again and the label will be shown, which is the way it is supposed to work. I dont know if the refresh behaviour can be altered, sorry.
