Error: objectdatasource could not find a non-generic method

I am binding dropdown list using Object data source. I got an error like this

"ObjectDataSource 'objDSStatus' could not find a non-generic method 'GetIssueAllowedStatusByCategoryIDStatusIDandUserType' that has parameters: IssueCategoryID."

My code is as fo开发者_开发技巧llows

.aspx

< asp:DropDownList ID="ddlStatus" runat="server" DataSourceID="objDSStatus" 
                                                DataTextField="IssueStatusName" DataValueField="IssueStatusID">                                                

< /asp:DropDownList>
< asp:ObjectDataSource ID="objDSStatus" runat="server" TypeName="DA"></asp:ObjectDataSource>

.cs

private void Bind(int IssueCategoryID, int IssueStatusID, int UserType)  
{  
    ddlStatus.Items.Clear();  
    objDSStatus.SelectMethod = "GetIssueAllowedStatusByCategoryIDStatusIDandUserType";  
    objDSStatus.SelectParameters.Clear();  
    objDSStatus.SelectParameters.Add("IssueCategoryID", IssueCategoryID.ToString());          
    objDSStatus.SelectParameters.Add("IssueStatusID", IssueStatusID.ToString());  
    objDSStatus.SelectParameters.Add("UserType", UserType.ToString());

    objDSStatus.DataBind();  
    ddlStatus.DataBind();  
}

DA.cs

public List<IssueStatus> GetIssueAllowedStatusByCategoryIDStatusIDandUserType(int IssueeCategoryID, int IssueStatusID, int UserType)  
{  
    List<IssueStatus> issueStatusList = new List<IssueStatus>();  
}  

Can anyone help me on this.

Thanks, Mahesh

This doesn't look right to me:

objDSStatus.SelectParameters.Add("IssueCategoryID", IssueCategoryID.ToString());
objDSFeedback.SelectParameters.Add("IssueStatusID", IssueStatusID.ToString());
objDSFeedback.SelectParameters.Add("UserType", UserType.ToString());

Did you mean to add the second and third parameters to objDSFeedback instead of objDSStatus? Your method has three parameters, after all...

Perhaps you meant this:

objDSStatus.SelectParameters.Add("IssueCategoryID", IssueCategoryID.ToString());
objDSStatus.SelectParameters.Add("IssueStatusID", IssueStatusID.ToString());
objDSStatus.SelectParameters.Add("UserType", UserType.ToString());

one of your DA.cs parameter is int IssueeCategoryID . It should be int IssueCategoryID
