如果我需要查找 GridView Template 内的任何 Control，更具体地说 FindControl 方法如何工作>项目模板？

我有一个超链接，但无法找到相同的内容。

用代码更新问题

GridView 代码如下：

<asp:GridView ID="grvYourOpportunities" runat="server" AllowPaging="True" AutoGenerateColumns="False"
        DataKeyNames="ID#,B,H" PageSize="20" CellPadding="4" ForeColor="#333333" GridLines="Both"
        OnRowDataBound="grvYourOpt_RowDataBound">
        <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
        <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
        <Columns>
          <asp:TemplateField>
                <HeaderTemplate>
                    i
                </HeaderTemplate>
                <ItemTemplate>
                    <%# Eval("i") %>
                </ItemTemplate>
            </asp:TemplateField>

            <asp:TemplateField>
                <HeaderTemplate>
                    H
                </HeaderTemplate>
                <ItemTemplate>

                    <%--<a href="javascript:ShowChildGrid('div<%# Eval("ID#") %>');">

                    <asp:HyperLink runat="server" ID="hlPlus" ImageUrl="~/plus.gif"></asp:HyperLink>

How does FindControl method works if I need to find any Control which is inside GridView Template, more specifically ItemTemplate?

I have a hyperlink but it is not able to find the same.

Question updated with code

GridView Code is below:

<asp:GridView ID="grvYourOpportunities" runat="server" AllowPaging="True" AutoGenerateColumns="False"
        DataKeyNames="ID#,B,H" PageSize="20" CellPadding="4" ForeColor="#333333" GridLines="Both"
        OnRowDataBound="grvYourOpt_RowDataBound">
        <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
        <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
        <Columns>
          <asp:TemplateField>
                <HeaderTemplate>
                    i
                </HeaderTemplate>
                <ItemTemplate>
                    <%# Eval("i") %>

试试这个：

foreach(GridViewRow row in GridView1.Rows) {
    if(row.RowType == DataControlRowType.DataRow) {
        HyperLink myHyperLink = row.FindControl("myHyperLinkID") as HyperLink;
    }
}

如果您正在处理 RowDataBound 事件，则如下所示：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
        HyperLink myHyperLink = e.Row.FindControl("myHyperLinkID") as HyperLink;
    }
}

Try this:

foreach(GridViewRow row in GridView1.Rows) {
    if(row.RowType == DataControlRowType.DataRow) {
        HyperLink myHyperLink = row.FindControl("myHyperLinkID") as HyperLink;
    }
}

If you are handling RowDataBound event, it's like this:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
        HyperLink myHyperLink = e.Row.FindControl("myHyperLinkID") as HyperLink;
    }
}

您可以使用此代码在 GridView 中查找 HyperLink。使用 e.Row.Cells[0].Controls[0] 查找 GridView 中控件的第一个位置。

protected void AspGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{    
  if(e.Row.RowType == DataControlRowType.DataRow)
    {
        DataRowView v = (DataRowView)e.Row.DataItem;           

        if (e.Row.Cells.Count > 0 && e.Row.Cells[0] != null && e.Row.Cells[0].Controls.Count > 0)
        {
            HyperLink link = e.Row.Cells[0].Controls[0] as HyperLink;
            if (link != null)
            {                    
                    link.Text = "Edit";
            }               
        }       

    }
}

You can use this code to find HyperLink in GridView. Use of e.Row.Cells[0].Controls[0] to find First position of control in GridView.

protected void AspGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{    
  if(e.Row.RowType == DataControlRowType.DataRow)
    {
        DataRowView v = (DataRowView)e.Row.DataItem;           

        if (e.Row.Cells.Count > 0 && e.Row.Cells[0] != null && e.Row.Cells[0].Controls.Count > 0)
        {
            HyperLink link = e.Row.Cells[0].Controls[0] as HyperLink;
            if (link != null)
            {                    
                    link.Text = "Edit";
            }               
        }       

    }
}

我已经完成了访问单元格控件内的控件。在所有控件集合中查找。

 ControlCollection cc = (ControlCollection)e.Row.Controls[1].Controls;

 Label lbCod = (Label)cc[1];

I have done it accessing the controls inside the cell control. Find in all control collections.

 ControlCollection cc = (ControlCollection)e.Row.Controls[1].Controls;

 Label lbCod = (Label)cc[1];

尝试使用下面的代码。

就像LinkBut​​ton、Label、HtmlAnchor 和HtmlInputControl 中的GridView 一样。

<asp:GridView ID="mainGrid" runat="server" AutoGenerateColumns="false" CssClass="table table-bordered table-hover tablesorter"
    OnRowDataBound="mainGrid_RowDataBound"  EmptyDataText="No Data Found.">
    <Columns>
        <asp:TemplateField HeaderText="HeaderName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center">
            <ItemTemplate>
                <asp:Label runat="server" ID="lblName" Text=' <%# Eval("LabelName") %>'></asp:Label>
                <asp:LinkButton ID="btnLink" runat="server">ButtonName</asp:LinkButton>
                <a href="javascript:void(0);" id="btnAnchor" runat="server">ButtonName</a>
                <input type="hidden" runat="server" id="hdnBtnInput" value='<%#Eval("ID") %>' />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

处理 RowDataBound 事件，

protected void mainGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        Label lblName = (Label)e.Row.FindControl("lblName");
        LinkButton btnLink = (LinkButton)e.Row.FindControl("btnLink");
        HtmlAnchor btnAnchor = (HtmlAnchor)e.Row.FindControl("btnAnchor");
        HtmlInputControl hdnBtnInput = (HtmlInputControl)e.Row.FindControl("hdnBtnInput");
    }
}

Try with below code.

Like GridView in LinkButton, Label, HtmlAnchor and HtmlInputControl.

<asp:GridView ID="mainGrid" runat="server" AutoGenerateColumns="false" CssClass="table table-bordered table-hover tablesorter"
    OnRowDataBound="mainGrid_RowDataBound"  EmptyDataText="No Data Found.">
    <Columns>
        <asp:TemplateField HeaderText="HeaderName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center">
            <ItemTemplate>
                <asp:Label runat="server" ID="lblName" Text=' <%# Eval("LabelName") %>'></asp:Label>
                <asp:LinkButton ID="btnLink" runat="server">ButtonName</asp:LinkButton>
                <a href="javascript:void(0);" id="btnAnchor" runat="server">ButtonName</a>
                <input type="hidden" runat="server" id="hdnBtnInput" value='<%#Eval("ID") %>' />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

Handling RowDataBound event,

protected void mainGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        Label lblName = (Label)e.Row.FindControl("lblName");
        LinkButton btnLink = (LinkButton)e.Row.FindControl("btnLink");
        HtmlAnchor btnAnchor = (HtmlAnchor)e.Row.FindControl("btnAnchor");
        HtmlInputControl hdnBtnInput = (HtmlInputControl)e.Row.FindControl("hdnBtnInput");
    }
}

如果您的 GridView 是 databond，请在您检索的结果集中创建一个索引列，如下所示：

select row_number() over(order by YourIdentityColumn asc)-1 as RowIndex, * from YourTable where [Expresion]

在要使用的命令控件中，使 CommandArgument 属性的值等于 DataSet 表 RowIndex 的行索引，如下所示：

<asp:LinkButton ID="lbnMsgSubj" runat="server" Text='<%# Eval("MsgSubj") %>' Font-Underline="false" CommandArgument='<%#Eval("RowIndex") %>' />

使用 OnRowCommand 事件来单击链接按钮时会像这样触发：

<asp:GridView ID="gvwStuMsgBoard" runat="server" AutoGenerateColumns="false" GridLines="Horizontal" BorderColor="Transparent" Width="100%" OnRowCommand="gvwStuMsgBoard_RowCommand">

最后，当事件被触发时，您后面的代码就可以做任何您喜欢的事情，如下所示：

protected void gvwStuMsgBoard_RowCommand(object sender, GridViewCommandEventArgs e)
{
    Panel pnlMsgBody = (Panel)gvwStuMsgBoard.Rows[Convert.ToInt32(e.CommandArgument)].FindControl("pnlMsgBody");
    if(pnlMsgBody.Visible == false)
    {
        pnlMsgBody.Visible = true;
    }
    else
    {
        pnlMsgBody.Visible = false;
    }
}

If your GridView is databond, make an index column in the resultset you retrive like this:

select row_number() over(order by YourIdentityColumn asc)-1 as RowIndex, * from YourTable where [Expresion]

In the command control you want to use make the value of CommandArgument property equal to the row index of the DataSet table RowIndex like this:

<asp:LinkButton ID="lbnMsgSubj" runat="server" Text='<%# Eval("MsgSubj") %>' Font-Underline="false" CommandArgument='<%#Eval("RowIndex") %>' />

Use the OnRowCommand event to fire on clicking the link button like this:

<asp:GridView ID="gvwStuMsgBoard" runat="server" AutoGenerateColumns="false" GridLines="Horizontal" BorderColor="Transparent" Width="100%" OnRowCommand="gvwStuMsgBoard_RowCommand">

Finally the code behind you can then do whatever you like when the event is triggered like this:

protected void gvwStuMsgBoard_RowCommand(object sender, GridViewCommandEventArgs e)
{
    Panel pnlMsgBody = (Panel)gvwStuMsgBoard.Rows[Convert.ToInt32(e.CommandArgument)].FindControl("pnlMsgBody");
    if(pnlMsgBody.Visible == false)
    {
        pnlMsgBody.Visible = true;
    }
    else
    {
        pnlMsgBody.Visible = false;
    }
}
