当它被选中的复选框总是返回true [英] Checkbox always returns true when it is unchecked

问题描述

我有嵌套的GridView 最后的GridView 的复选框。

在检查条件的复选框无论是选中或取消选中

 的foreach（在GridView1.Rows GridViewRow GVR）
{
       GridView控件GridView2 = gvr.FindControl（GridView2）作为GridView控件;
       的foreach（在GridView2.Rows GridViewRow gvr2）
       {
           GridView控件GridView3 = gvr2.FindControl（GridView3）作为GridView控件;
           的foreach（在GridView3.Rows GridViewRow gvr3）
           {
               如果（（（复选框）gvr3.FindControl（CHK1））。经过）
               {
                    字符串的txt = txtKeyboard.text;
               }
           }
       }
}
 

即使它未被选中它会去，虽然条件

解决方案

 如果（（（复选框）gvr3.FindControl（CHK1））。经过）
{
     字符串的txt = txtKeyboard.text;
}
 

而不是上面code只是尝试一次。

 复选框CHK1 = gvr3.Cells [0] .Controls [0]为复选框;
  如果（chk1.checked ==真）
  {
      字符串的txt = txtKeyboard.text;
  }
 

在这里你需要设置 0

的单元格值和控制值就地

I have nested Gridview and the last Gridview has Checkbox.

the condition in checking the Checkbox whether it is checked or unchecked

foreach (GridViewRow gvr in GridView1.Rows)
{
       GridView GridView2= gvr.FindControl("GridView2") as GridView;
       foreach (GridViewRow gvr2 in GridView2.Rows)
       {
           GridView GridView3= gvr2.FindControl("GridView3") as GridView;
           foreach (GridViewRow gvr3 in GridView3.Rows)
           {
               if(((CheckBox)gvr3.FindControl("chk1")).Checked)
               {
                    string txt = txtKeyboard.text;
               }
           }
       }
}

even though it is unchecked it will go though the condition

解决方案

if(((CheckBox)gvr3.FindControl("chk1")).Checked)
{
     string txt = txtKeyboard.text;
}

instead of above code just try once

  CheckBox chk1 = gvr3.Cells[0].Controls[0] as CheckBox;
  if(chk1.checked==true)
  {
      string txt = txtKeyboard.text;
  }

here you need to set cell value and control value inplace of 0
