Gridview 保持在编辑模式

Question

My Gridview refuses to exit edit mode. When I hit press the Update link, everything works as it should as far as the database being updated, but the Gridview row remains in edit mode. When I press the Cancel button, the Gridview reflects the new information. Why does the row remain in Edit Mode even after setting the EditIndex to -1?

I'm sure it's something really remedial, but I can't find any help with getting a gridview out of edit mode that doesn't just tell me to set the edit index.

protected void Gridview_RowUpdating(object sender, GridViewUpdateEventArgs e) {
    // Update code is here and works fine
    try {
        // this works and updates the database w/ no problems
        ObjectDataSource.Update();
    }
    catch (Exception ex) {
    }

    Gridview.EditIndex = -1;
    Gridview.DataBind();            
}

EDIT: I took out the try/catch and nothing seems to fail, but I do still have to explicitly call the ObjectDataSource.Update() So, here's the setup for my GridView:

<asp:Gridview ID="Gridview" runat="server" DataSourceID="ObjectDataSource" DataKeyNames="ID" OnDataBound="Gridiew_DataBound"
                AutoGenerateColumns="false" OnRowCommand="Gridview_RowCommand" OnRowUpdating="Gridview_RowUpdating">

And the ObjectDataSource

<asp:ObjectDataSource ID="ObjectDataSource" runat="server" TypeName="DAL.Class" SelectMethod="SelectMethod" UpdateMethod="UpdateMethod">
    <UpdateParameters>
        <asp:Parameter Name="param1" Type="Int32" />
        <asp:Parameter Name="param2" Type="String" />
        <asp:Parameter Name="param3" Type="String" />
        <asp:Parameter Name="param4" Type="String" />
        <asp:Parameter Name="param5" Type="String" />
        <asp:Parameter Name="param6" Type="Int32" />
        <asp:Parameter Name="param7" Type="String" />
        <asp:Parameter Name="param8" Type="Int32" />
    </UpdateParameters>
</asp:ObjectDataSource>

So, what is set up incorrectly, that it isn't automatically updating?

EDIT 2: So, I'm now setting the parameter values in the ObjectDataSource_Updating event (which wasn't being called before which is why I had the explicit called to the ods_update()). Now the _Updating event is being hit, but it never goes into my DAL method. Again, no errors are thrown, it just doesn't do anything....

Answer 1

Maybe something bad is happening like the edit is failing. And since you are hiding errors:

catch (Exception ex) {
    }

...you can't see what's happening.

If the GridView/DataSource is setup properly, you don't need to explicitly call Update or DataBind.

Answer 2

Can you give a shot by updating a dummy table? (in Gridview_RowUpdating event)

 ObjectDataSource.UpdateCommand = @"UPDATE somedummytable set  parameter";   
ObjectDataSource.Update();     
Gridview.EditIndex = -1;       
    ObjectDataSource.DataBind();     
Gridview.DataBind();    

After this step, I am sure it will come out of edit mode.

Answer 3

In case this helps anyone, make sure you update your Edit Index after update/cancel:

GridView1.EditIndex = -1

That did it for me.
