 受保护的  void  drpClaimNumber_SelectedIndexChanged(对象发​​件人，EventArgs e)
       {
            int  claimId =  int  .Parse(drpClaimNumber.SelectedValue.ToString());
           cmd = 新 SqlCommand("  Edit_ClaimDetails"  ，con1);
           cmd.CommandType = CommandType.StoredProcedure;
           cmd.Parameters.Add("  @ Claim_Id" ，SqlDbType.VarChar).Value = ClaimId;
           con1.Open();
           cmd.Connection = con1;
           SqlDataAdapter ada = 新 SqlDataAdapter(cmd);
           ada.Fill(ds);
           {
               如果(ds.Tables [ 0 ].Rows.Count  >   0 )
               {

                   txtFirstName.Text = ds.Tables [ 0 ].行[ 0 ] ["  名字"].ToString();
                   txtLastName.Text = ds.Tables [ 0 ].行[ 0 ] ["  姓氏"].ToString();
                   txtAddress.Text = ds.Tables [ 0 ].行[ 0 ] ["  地址1"].ToString();
                   txtPolicyNumber.Text = ds.Tables [ 0 ].rows [ 0 ] ["   policy_number"].ToString();
                   txtDateOfLoss.Text = ds.Tables [ 0 ].Rows [ 0 ] ["   date_of_loss"].ToString();
                   txtAdditionalDetails.Text = ds.Tables [ 0 ].rows [ 0 ] ["   additional_details"].ToString();

                   字符串 sel_policy = ds.Tables [ 0 ].行[ 0 ] ["  policy_description" ].ToString();
                     int  indx1 = drpPolicyType.Items.IndexOf(drpPolicyType.Items.FindByText(sel_policy));
                     drpPolicyType.SelectedIndex = indx1;



                         字符串 sel_claims = ds.Tables [ 0 ].行[ 0 ] ["  claims_description" ].ToString();
                          int  indx2 = drpClaimType.Items.IndexOf(drpClaimType.Items.FindByText(sel_claims));
                         drpClaimType.SelectedIndex = indx2;



              }

               con1.Close();
           }
       } 

请检查此代码.实际上以我的形式他们是2 drpdown
一个.政策类型
b.索赔类型

声明类型drpdown与策略类型有关.
现在我正在编辑零件.

当我选择任何索赔编号时，它会在各个文本框和下拉列表中显示所有详细信息.但是问题是当我选择任何索赔编号时，我无法查看我的表格中接受索赔类型drpdown"的每个字段.在保单类型drpdown中，我可以在选择无要求后查看顶部，但是我无法查看索赔类型drpdown说明.我选择了policytype drpdwn autopostback属性true.

请告诉我，如何根据所选的索赔编号查看索赔类型下拉列表.
