Question

我有一个gridview可以正常使用我的每个行命令，但是，一旦它被排序，它会导致rowdatabound事件使用不正确的值，而不是排序后的行中的实际值。任何帮助将不胜感激！

这是我背后的代码。

 //Verify and Update Record
protected void UnverifiedSalesGV_RowCommand(object sender, GridViewCommandEventArgs e)
{
    buttonCommand = e.CommandName;
    MessageLBL.Text = "";

    if (e.CommandName == "VerifyRecord")
    {

        //Get record ID
        string salesID = UnverifiedSalesGV.DataKeys[Convert.ToInt32(e.CommandArgument)].Value.ToString();

        //Get productID 
        SalesData getSalesRecord = new SalesData();
        getSalesRecord.GetRowValuesSalesID(salesID);

        string productID = getSalesRecord.productID;


        if (productID != "38")
        {
            verifyRenewal = false;
            try
            {
                UpdateSalesRecordSDS.UpdateCommand = "UPDATE Sales SET Verified = @Verified WHERE ID = @ID";
                UpdateSalesRecordSDS.UpdateParameters["ID"].DefaultValue = UnverifiedSalesGV.DataKeys[Convert.ToInt32(e.CommandArgument)].Value.ToString();
                UpdateSalesRecordSDS.UpdateParameters["Verified"].DefaultValue = true.ToString();
                UpdateSalesRecordSDS.Update();

                UnverifiedSalesGV.DataBind();
                VerifiedSalesGV.DataBind();

我终于能够通过下面的硬编码来解决我的问题了：

 //Hide and show fields
protected void UnverifiedSalesGV_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowIndex == rowIndex)
    {
        string state = e.Row.RowState.ToString();
        if (state == "Alternate, Edit" || state == "Edit")
        {

            //Get record ID
            string salesID = UnverifiedSalesGV.DataKeys[Convert.ToInt32(e.Row.DataItemIndex)].Value.ToString();

            //Get productID 
            SalesData getSalesRecord = new SalesData();
            getSalesRecord.GetRowValuesSalesID(salesID);

            string productID = getSalesRecord.productID;

            if (productID == "38")
            {
                //Items to Hide/Display
                Button UpdateProductBTN = (Button)e.Row.FindControl("UpdateProductBTN");
                Button UpdateBTN = (Button)e.Row.FindControl("UpdateBTN");
                Label productLBL = (Label)e.Row.FindControl("CurrentProductLBL");
                Label accountManagerLBL = (Label)e.Row.FindControl("AccountManagerLBL");
                DropDownList productDDL = (DropDownList)e.Row.FindControl("RenewalProductDDL");
                DropDownList accountManagerDDL = (DropDownList)e.Row.FindControl("AccountManagerDDL");
                Label grossSalesLBL = (Label)e.Row.FindControl("GrossSalesLBL");
                TextBox grossSalesTXT = (TextBox)e.Row.FindControl("GrossSalesTXT");
                Label netSalesLBL = (Label)e.Row.FindControl("NetSalesLBL");
                TextBox netSalesTXT = (TextBox)e.Row.FindControl("NetSalesTXT");
                Label commissionMonthLBL = (Label)e.Row.FindControl("SalesCommissionLBL");
                DropDownList commissionMonthDDL = (DropDownList)e.Row.FindControl("CommissionMonthDDL");
                TextBox notesTXT = (TextBox)e.Row.FindControl("NotesTXT");
                Label notesLBL = (Label)e.Row.FindControl("NotesLBL");


                UpdateProductBTN.Visible = true;
                UpdateBTN.Visible = false;
                productLBL.Visible = false;
                productDDL.Visible = true;
                accountManagerLBL.Visible = true;
                accountManagerDDL.Visible = false;
                grossSalesLBL.Visible = true;
                grossSalesTXT.Visible = false;
                netSalesLBL.Visible = true;
                netSalesTXT.Visible = false;
                commissionMonthLBL.Visible = true;
                commissionMonthDDL.Visible = false;
                notesTXT.Visible = false;
                notesLBL.Visible = true;
            }
        }
    }
}
