The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

InsertItemTemplate textbox value passes null to ObjectDataSource

Asked by dcadler in Programming for ASP.NET, Microsoft Visual C#.Net, Visual Studio

Tags: ObjectDataSource, InsertItemTemplate, Null value

I have an aspx file that is using an ObjectDataSource. In the aspx form, I am using item templates. I have a textbox control in the InsertItemTemplate that I have have the text value bound to a database field, "DXCode". In this same InsertItemTemplate, I have other textbox fields bound in the same way to other database fields. When I click to insert the record, the value in the textbox for "DXCode" is always null but the other fields pass their values just fine.

I tried adding an InsertParameter in the ObjectDataSource definition and used the ObjectDataSource's Inserting event to put the value in the textbox into the InsertParameter value. I can see that the value is in the textbox and passed to the InsertParameter item's default value, but it is still null when it gets to the Dababase class InsertRecord code.

I use a class called DXCodeDetails.cs that is used to hold the record data and a class called DXCodeDB.cs that has all of the database interface code. The DXCodeDetails class is working OK because I can view existing records using it.I can also edit existing records. I just can not get the DXCode value to pass through to the DXCodeDB.cs class when I use the InsertItemTemplate.

I breakpoint the code in the DXCodeDB.cs file at the start of the Insert record code and I can see that all of the values except the DXCode value are passed in, the DXCode value is null.

I am stumped at this point.

Any ideas?

             Here is the Object Datasource code
 
    <asp:ObjectDataSource 
        ID="sourceDXCode" 
        runat="server" 
        TypeName="DXCodeDB" 
        SelectMethod="GetDXCode" 
        OnSelecting="sourceDXCode_Selecting" 
        OnSelected="sourceDXCode_Selected"
        DataObjectTypeName="DXCodeDetails" 
        UpdateMethod="UpdateDXCode" 
        OnUpdating="sourceDXCode_Updating" 
        InsertMethod="InsertDXCode" 
        OnInserting="sourceDXCode_Inserting" 
        OnInserted="sourceDXCode_Inserted"
        DeleteMethod="DeleteDXCode" 
        OldValuesParameterFormatString="original_{0}"
        onDeleted="sourceDXCode_Deleted">
        <SelectParameters>
            <asp:ControlParameter ControlID="ddlDXCodes" Name="DXCode" PropertyName="SelectedValue" />        
        </SelectParameters>
        <InsertParameters>
            <asp:Parameter Direction="Input" Name="DXCode" Type="String" />
        </InsertParameters>
 
    </asp:ObjectDataSource>
 
Here is the textfield definition in the InsertItemTemplate
 
                                    <asp:TextBox ID="txtInsert_Code" Text="<%# Bind('DXCode') %>" runat="server" cssClass="frmTextBox" OnLoad="txtInsert_Code_Load"></asp:TextBox>
