我有一个gridview我绑定与GridView控件其动态所以没有硬code在DESIN文本数据表。

我试过后，数据绑定和GridView的，但没有成功的preRender去改变它。

其实有下划线（_）的文本，我想用空格替换它。

下面是code

 ＆LT; ASP：GridView控件ID =grdSearchResult=服务器的AutoGenerateColumns =真WIDTH =99％在preRender =grdSearchResult_ preRender 
            OnRowCreated =grdSearchResult_OnRowCreatedOnPageIndexChanging =grdSearchResult_PageIndexChanging＆GT;
            ＆LT; HeaderStyle前景色=白背景色=＃215B8D/＆GT;
            ＆LT; AlternatingRowStyle背景色=＃F7F7F7/＆GT;
            ＆LT; RowStyle的CssClass =gridtextHorizo​​ntalAlign =中心/＆GT;
        ＆LT; / ASP：GridView控件＆GT;



保护无效grdSearchResult_ preRender（对象发件人，EventArgs的）
{
    的for（int i = 0; I＆LT; grdSearchResult.Columns.Count;我++）
    {
        grdSearchResult.Columns [I] .HeaderText = grdSearchResult.Columns [Ⅰ] .HeaderText.Replace（_，）;
    }
}
 

解决方案

能做到这一点与的RowDataBound GridView控件的事件

 保护无效grdSearchResult_RowDataBound（对象发件人，GridViewRowEventArgs E）
{
     如果（e.Row.RowType == DataControlRowType.Header）
     {
        的for（int i = 0; I＆LT; e.Row.Cells.Count;我++）
        {
            e.Row.Cells [I]。文= e.Row.Cells [Ⅰ] .Text.Replace（_，）;
        }
     }
}
 

和它工作正常。

I have a gridview I bound a DataTable with that Gridview Its dynamic so no hardcode Text in desin.

I tried to change it after Databound and in PreRender of gridview but no Success.

Actually there are Underscores('_') in text and I want to Replace it with space.

Below is code

<asp:GridView ID="grdSearchResult" runat="server" AutoGenerateColumns="True" Width="99%" OnPreRender="grdSearchResult_PreRender"
            OnRowCreated="grdSearchResult_OnRowCreated" OnPageIndexChanging="grdSearchResult_PageIndexChanging">
            <HeaderStyle ForeColor="White" BackColor="#215B8D" />
            <AlternatingRowStyle BackColor="#F7F7F7" />
            <RowStyle CssClass="gridtext" HorizontalAlign="Center" />
        </asp:GridView>



protected void grdSearchResult_PreRender(object sender, EventArgs e)
{
    for (int i = 0; i < grdSearchResult.Columns.Count; i++)
    {
        grdSearchResult.Columns[i].HeaderText = grdSearchResult.Columns[i].HeaderText.Replace("_", "");
    }
}

Can do this with RowDataBound event of GridView

protected void grdSearchResult_RowDataBound(object sender, GridViewRowEventArgs e)
{
     if (e.Row.RowType == DataControlRowType.Header)
     {
        for (int i = 0; i < e.Row.Cells.Count; i++)
        {
            e.Row.Cells[i].Text = e.Row.Cells[i].Text.Replace("_", " ");
        }
     }
}

and it works fine.
