How to access ViewState of one page in another page in Asp.Net?

You can't access ViewState of one page from another page directly. If you want to access a particular ViewState value then you can pass the value in Context collection and then access the value in other page.

In Page 1:

Context.Items.Add("employee" ,ViewState["employee"].ToString());

In Page 2:

string employeeName = Context.Items["employee"].ToString();

How to: Disable Button after Click while maintaining CausesValidation and an OnClick-Method

Here is how you can do it by adding these two lines in your code behind to prevent multiple clicks on a button.

string strProcessScript = "if (!Page_ClientValidate()){ return false; } else{ this.value='Processing...';this.disabled=true; }";
CheckOutButton.Attributes.Add("onclick", strProcessScript + ClientScript.GetPostBackEventReference(CheckOutButton, "").ToString());

If you have ASP.NET Validation controls in your page, then you might need to do this by adding specific validation group to Page_ClientValidate method.

string strProcessScript = "if (!Page_ClientValidate('PaymentValidationGroup')){ return false; } else{ this.value='Processing...';this.disabled=true; }";
CheckOutButton.Attributes.Add("onclick", strProcessScript + ClientScript.GetPostBackEventReference(CheckOutButton, "").ToString());

 

Only thing you need to change in ASPX is to add following attribute in ASP Button code UseSubmitBehavior="false"

 

<asp:Button runat="server" ID="PaymentCheckOutButton" ValidationGroup="PaymentValidationGroup"                                          
Text="Proceed to Checkout" UseSubmitBehavior="false" class="btn btn-primary btn-cons pull-right" OnClick="PaymentCheckOutButton_Click" />

 

Hope this helps!!
