DetailsView loses controls state and binding after an exception occurs Alex Getman5-Sep-07 22:49 Alex Getman 5-Sep-07 22:49  Hi. I'm using ASP.NET 2.0 and MS SQL Server 2005 environment. I'm developing an aspx page which is using DetailsView to insert data. There are several TemplateFields are located at the DetailsView control. These Template fields containing TextBox and DropDownlList controls and I'm passing values of these controls using %Bind% syntax: <asp:DetailsView ID="dvCity" runat="server" AutoGenerateRows="False" DataKeyNames="Id" DataSourceID="sdsCity" DefaultMode="Insert" OnItemInserted="dvCity_ItemInserted"> <Fields> <asp:BoundField DataField="Id" HeaderText="Id" InsertVisible="False" ReadOnly="True" SortExpression="Id" Visible="False" /> <asp:TemplateField HeaderText="Name"> <InsertItemTemplate> <asp:TextBox ID="txbName" runat="server" Text='<%# Bind("Name") %>'></asp:TextBox> <asp:RequiredFieldValidator ID="rfvName" runat="server" ControlToValidate="txbName" SetFocusOnError="true" Display="Dynamic" ErrorMessage="You must specify a non-blank value for Name.">*</asp:RequiredFieldValidator> </InsertItemTemplate> </asp:TemplateField> <asp:BoundField DataField="RegionId" HeaderText="RegionId" SortExpression="RegionId" Visible="False" /> <asp:TemplateField HeaderText="Region"> <InsertItemTemplate> <asp:DropDownList ID="ddlRegion" runat="server" DataSourceID="sdsRegion" DataTextField="Name" DataValueField="Id" SelectedValue='<%# Bind("RegionId") %>'> </asp:DropDownList> </InsertItemTemplate> </asp:TemplateField> </Fields> </asp:DetailsView> DataSource for the DetailsView is the SqlDataSource which is using StoredProcedures to insert data into Database. Some parts of business logic are located in the T-SQL code of the StoredProcedure and in case of any error I'm throwing exception from T-SQL using RAISE_ERROR method. In the aspx.cs, OnItemInserted event of the DetailsView I've implemented following code for exception processing: protected void dvCity_ItemInserted(object sender, DetailsViewInsertedEventArgs e) { if (e.Exception != null) throw e.Exception; else Response.Redirect("City.aspx"); } When there is no error during StoredProcedure execution everything is works fine. When my StoredProcedure raises any exception and this exception was handled by my handler user sees the AJAX popup and clicks OK. Then popup closes, user edits values in DetailsView controls, clicks Save again BUT I got another exception saying that ((TextBox)dvCity.FindControl("txtName")) is NULL. The same is for DropDownList. It seems to me that DetailsView loses databinding after an exception occurs during Insert/Update operation. <b>Does anyone can help me how to handle or re-throw exception without DetailsView unbind?</b> http://www.jetideas.com Tracing Priya S5-Sep-07 22:20 Priya S 5-Sep-07 22:20  Hi, i would like to trace my code using breakpoints, but its not working,while running appln, even i checked properties in "debug" tab-all breakpoints enabled, also tried with <trace="true">Please suggest me...

If it is any other change it to debug. Shujaat ASP 2.0 Deployment pksno15-Sep-07 22:04 pksno1 5-Sep-07 22:04  Hi there, Anyone gone through deployment process in ASP 2.0. Please educate me on this - I want my site updatable (I know how to do that) but compile and deploy process always complies all the files - now how do I know what all dll and source code has been changed on my last build. This is more related to tracking changes in VSS or any config mgmnt s/w - I just want to update one aspx and get one dll for it (I have congigured build-deployment as one dll for each as*x), I couldn't find any info on this aspect, please let me know how to achieve the goal. Even if I have one dll as output for the website with updatable aspx/ascx (using web deployment project) it gives me all the aspx complied with latest datetime stamp, so if I don't keep track of what all files I modified - I have to deploy entire website again. Instead it should be something like I changed 5 aspx, got them complied, and deployed the modified aspx plus new dll - I don't find a proper way...please guide.
