如何动态更改gridview超链接字段 [英] How do I dynamically change a gridview hyperlinkfield
问题描述
我有一个gridview w /一个超链接字段列。我正在寻找一些方法来指定超链接域的NavigateURL，基于gridview中其他列之一的值。例如，如果数据绑定列包含car，则NavigateURL应为〜/ myweb / car.aspx.........同样，如果列包含truck，则NavURL应为〜/ myweb /truck.aspx。
我尝试过：

代码尝试1：
protected void GridView2_RowDataBound（object sender，GridViewRowEventArgs e）
{
if（row.Cells [1] .Text ==ATP）
{
HyperLink hl = e.Row.FindControl（Hyperlink1）作为HyperLink;
hl.NavigateUrl =〜/ Reports / LabDetail / ATPDetails.aspx;
}
if（row.Cells [1]。文字==水）
{
HyperLink hl = e.Row.FindControl（Hyperlink1）作为HyperLink;
hl。 NavigateUrl =〜/ Reports / LabDetail / WaterDetails.aspx;
}
< br $>
}
代码尝试2：
protected void GridView2_RowDataBound（object sender，GridViewRowEventArgs e）
{
foreach（GridView2.Rows中的GridViewRow行）
{
if（row.Cells [1] .Text ==ATP）
{
HyperLink hl = e .Row.FindControl（Hyperlink1）作为HyperLink;
hl.NavigateUrl =〜/ Reports / LabDetail / ATPDetails.aspx;
}
if（row.Cells [1] .Text ==Water）
{
HyperLink hl = e.Row.FindControl（Hyperlink1）as HyperLink;
hl.NavigateUrl =〜/ Reports / LabDetail / WaterDetails.aspx;
}
}
}
I have gridview w/ a hyperlinkfield column. I am looking for some means of specifying the NavigateURL of the hyperlinkfield, based on the value in one of the other columns in the gridview. For instance, if databound column contains "car", the NavigateURL should be "~/myweb/car.aspx".........likewise, if column contains "truck", the NavURL should be "~/myweb/truck.aspx".
What I have tried:
Markup:
<asp:GridView ID="GridView2" runat="server" AllowPaging="True" AutoGenerateColumns="False" CellPadding="4" DataSourceID="SqlDataSource2" ForeColor="#333333" GridLines="None" OnSelectedIndexChanged="GridView2_SelectedIndexChanged" OnRowDataBound="GridView2_RowDataBound">

<asp:TemplateField HeaderText="aaaa">

Code Attempt 1:
protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (row.Cells[1].Text == "ATP")
{
HyperLink hl = e.Row.FindControl("Hyperlink1") as HyperLink;
hl.NavigateUrl = "~/ Reports / LabDetail / ATPDetails.aspx";
}
if (row.Cells[1].Text == "Water")
{
HyperLink hl = e.Row.FindControl("Hyperlink1") as HyperLink;
hl.NavigateUrl = "~/ Reports / LabDetail / WaterDetails.aspx";
}
}
Code Attempt 2:
protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
{
foreach (GridViewRow row in GridView2.Rows)
{
if (row.Cells[1].Text == "ATP")
{
HyperLink hl = e.Row.FindControl("Hyperlink1") as HyperLink;
hl.NavigateUrl = "~/ Reports / LabDetail / ATPDetails.aspx";
}
if (row.Cells[1].Text == "Water")
{
HyperLink hl = e.Row.FindControl("Hyperlink1") as HyperLink;
hl.NavigateUrl = "~/ Reports / LabDetail / WaterDetails.aspx";
}
}
}
试试这个
try this
protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string text = e.Row.Cells[1].Text;
HyperLink hl = e.Row.FindControl("Hyperlink1") as HyperLink;
if (hl != null)
{
if (text == "ATP")
hl.NavigateUrl = "~/Reports/LabDetail/ATPDetails.aspx";
else if (text == "Water")
hl.NavigateUrl = "~/Reports/LabDetail/WaterDetails.aspx";
}
}
}
最终代码（正常工作）
protected void GridView2_RowDataBound（对象发送者，GridViewRowEventArgs e）
{
foreach（GridView2.Rows中的GridViewRow行）
{
if（row.Cells [1] .Text ==ATP）
{
HyperLink hl = row.FindControl（HyperLink1 ）作为HyperLink;
hl.NavigateUrl =〜/ Reports / LabDetail / ATPDetails.aspx;
}
if（row.Cells [1] .Text ==Water）
{
HyperLink hl = row.FindControl（HyperLink1）作为HyperLink;
hl.NavigateUrl =〜/ Reports / LabDetail / WaterDetails.aspx;
}
}
}
final code (working)
protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
{
foreach (GridViewRow row in GridView2.Rows)
{
if (row.Cells[1].Text == "ATP")
{
HyperLink hl = row.FindControl("HyperLink1") as HyperLink;
hl.NavigateUrl = "~/Reports/LabDetail/ATPDetails.aspx";
}
if (row.Cells[1].Text == "Water")
{
HyperLink hl = row.FindControl("HyperLink1") as HyperLink;
hl.NavigateUrl = "~/Reports/LabDetail/WaterDetails.aspx";
}
}
}
