UpdatePanel Full Postback
- by Korivo
Greetings, here is the scenario.
I have and .aspx page with and updatepanel like this
<asp:UpdatePanel id="uPanelMain" runat="server">
<ContentTemplate>
<uc:Calendar id="ucCalendar" runat="server" Visible="true" />
<uc:Scoring id="ucScoring" runat="server" Visible="false" />
</ContentTemplate>
The control ucCalendar is loaded first and it contains a grid like this
<asp:DataGrid CssClass="grid" ID="gridGames" runat="server" AutoGenerateColumns="False" HeaderStyle-CssClass="gridHeader" ItemStyle-CssClass="gridScoringRow"
GridLines="None" ItemStyle-BackColor="#EEEEEE" AlternatingItemStyle-BackColor="#F5F5F5"
OnEditCommand="doScoreGame" OnDeleteCommand="doEditGame" OnCancelCommand="printLineup" OnItemDataBound="gridDataBound">
<Columns>
<asp:TemplateColumn >
<ItemTemplate>
<asp:CheckBox ID="chkDelete" runat="server" />
</ItemTemplate>
</asp:TemplateColumn>
<asp:BoundColumn DataField="idGame" Visible="false" />
<asp:BoundColumn DataField="isClose" Visible="false" />
<asp:TemplateColumn HeaderText="Status">
<ItemTemplate>
<asp:Image ID="imgStatus" runat="server" ImageUrl="~/img/icoX.png" alt="icoStatus" />
</ItemTemplate>
</asp:TemplateColumn>
<asp:TemplateColumn>
<ItemTemplate>
<asp:LinkButton ID="linkScore" runat="server" CommandName="Edit" Text="Score" />
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:DataGrid>
So when i click the "linkButton", the codebehind of the userControl calls a public method in the .aspx as this:
From the userControl
protected void doScoreGame(object sender, DataGridCommandEventArgs e)
{
((GM)this.Page).showScoring(null, null);
}
From the .aspx page
public void showScoring(object sender, EventArgs e)
{
removeLastLoadedControl();
ucScoring.Visible = true;
}
So, here comes the problem:
There are two postbacks taking place when I change the visible attribute of the ucScoring control.
The first postback is fine, it's handled by the updatePanel.
The second postback is a full postback, and i really don't understand why it is happening.
I'm really lost here, please help!
Thanks
Mat
