If my understanding is correct, the following code can demonstrate your
scenario. For the simplicity I use TextBox to replace the FormView in your
case.
aspx:
<asp:Wizard ID="Wizard1" runat="server" ActiveStepIndex="0">
<WizardSteps>
<asp:WizardStep ID="WizardStep1" runat="server" Title="Step
1">
</asp:WizardStep>
<asp:WizardStep ID="WizardStep2" runat="server" Title="Step
2">
<asp:TextBox ID="TextBox1" runat="server"
OnPreRender="TextBox1_PreRender"></asp:TextBox>
</asp:WizardStep>
<asp:WizardStep ID="WizardStep3" runat="server"
Title="Step 3">
</asp:WizardStep>
</WizardSteps>
</asp:Wizard>
aspx.cs:
protected void TextBox1_PreRender(object sender, EventArgs e)
{
TextBox t = (TextBox)sender;
t.Text = "Default Value";
}
The problem is, if you go to step 2, change the value in the TextBox and
then go to step 3 and back to step 2. The value you changed is overwritten
because "Default Value" is reset in the PreRender event of TextBox.
The solution is, save a flag in ViewState, which can be preserved during
postbacks. We can use this flag to know if it's the first time to assign
value to TextBox.
The updated code:
protected void TextBox1_PreRender(object sender, EventArgs e)
{
if (ViewState["thefirsttime"] == null)
{
ViewState["thefirsttime"] = false;
TextBox t = (TextBox)sender;
t.Text = "Default Value";
}
}
Please test it and let me know if it works. If I misunderstood you please
send me a repro project. I'll test it on my side. My email is
. Please update here after sending the project in case
I missed that email.
