Gridview显示& nbps; [英] Gridview shows &nbps;

问题描述

你好，



我有一个gridview，当我得到列的selecteditem.cells时，如果数据库列为Null或Empty，我指定了对于我的网络表单文本控件，控件显示 而不是string.empty。我怎么能解决这个问题。

解决方案

你可以尝试这个...



让我们说你的gridview在RowDataBound方法中称为gvUsers你可以尝试这个...

  protected   void  gvUsers_RowDataBound（ object  sender，GridViewRowEventArgs e）
 {
 < span class =code-keyword> if （e.Row.RowType！= DataControlRowType.DataRow） return ; 
 
 DataRow CurrentRow =（（DataRow）sender）; 
  for （ int  i =  0 ; i <  CurrentRow.ItemArray.Count（）; i ++）
  if （ CurrentRow.ItemArray [i] .ToString（）==  ）
 CurrentRow.ItemArray [i] =  string  .Empty; 
} 

如果数据库表中的列具有空字符串或空值，则可以指定空字符串或某些默认文本。

hello,

I have a gridview, when I get the selecteditem.cells for a column, if the database column is Null or Empty, and I assign that to my web form text control, the control reads " " instead of a string.empty. How can i solve this .

解决方案

You could try this...

Let say your gridview is called gvUsers in the RowDataBound method you could try this...

protected void gvUsers_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType != DataControlRowType.DataRow) return;

        DataRow CurrentRow = ((DataRow)sender);
        for (int i = 0; i < CurrentRow.ItemArray.Count(); i++)
            if (CurrentRow.ItemArray[i].ToString() == " ")
                CurrentRow.ItemArray[i] = string.Empty;
    }

You can assign an empty string or some default text in case your column in the database table is having an empty string or null value.
