字段不填充？ [英] Fields don't Populate ?

问题描述

亲爱的所有人，



我在运行时编写以下代码，从数据库中检索字段，但不分配给它的文本字段是否错误。



这是我的代码。

Dear All ,

I am writing the following code at run time it retrieve the fields from data base but do not assign to the text fields whats wrong with it.

Here is my code .

protected void btnSearch_Click(object sender, EventArgs e)
       {
           int sno=int.Parse(txtStID.Text.ToString());

           ResultDbContext rc = new ResultDbContext();
           TblResult res=rc.TblResults.ToList().Where(x=>
           x.StID==int.Parse(txtStID.Text)).First();


           if ((res.Class == "XI") && (res.SGroup == "Pre-Engineering"))
         {
             txtName.Text = res.SName;
             txtFName.Text = res.FName;
             txtClass.Text = res.Class;
             txtSGroup.Text = res.SGroup;
             txtEng1.Enabled = true;
             txtEng1.Text = res.Eng1.ToString();
             txtUrdu1.Enabled = true;
             txtPhy1.Text = res.Phy1.ToString();
             txtChem1.Enabled = true;
             txtChem1.Text = res.Chem1.ToString();
             txtMath1.Enabled = true;
             txtMath1.Text = res.Math1.ToString();

         }
        }

推荐答案

我们无法运行您的代码所以没办法让我们知道出了什么问题。您正在为Text属性分配值，以便部分正常。但是，您必须调试自己的代码，因为我们无法运行它。也许res.Class不等于XI或者res.SGroup！=Pre-Engineering或res.SName是空白的。我们无从知晓。你必须调试它。

We cannot run your code so there is no way for us to know what is wrong. You are assigning values to the Text property so that part is OK. However, you'll have to debug your own code since we can't run it. Perhaps res.Class does not equal "XI" or perhaps res.SGroup != "Pre-Engineering" or res.SName is blank. There is no way we can know. You have to debug it.
