如何在asp.net中获取GridView单元格值 [英] How to get the gridview cell value in asp.net
问题描述
Gridview如下
链接课程代码天数Startdt Enddt
单击此处ASM CC 5 2015年5月10日2015年5月15日
2015年5月21日2015年5月25日
当我单击gridview中的链接按钮时，我想获取该课程的Course(ASM)，如下所示:
受保护的void LinkButton2_Click(对象发送者，EventArgs e)
{
for(int i = 0; i< gvRank.Rows.Count; i ++)
{
字符串Course = gvRank.SelectedRow.Cells [1] .Text;
Session ["course"] =课程；
{
Response.Redirect("Eligibility.aspx");
}
}
}
但是当我调试并检查以下行时，如下所示
字符串Course = gvRank.SelectedRow.Cells [1] .Text;
在上面的行中，不会检索课程名称.
请帮我上面的代码有什么问题

请找到下面的代码来解决您的问题，
Aspx:
Please find below code to resolve your problem,
Aspx:
<div>
<asp:gridview runat="Server" id="gvRank" autogeneratecolumns="False" autogenerateselectbutton="True" onselectedindexchanged="gvRank_SelectedIndexChanged" style="z-index: 100; left: 266px; position: absolute; top: 71px" cellpadding="4" forecolor="#333333" gridlines="None" width="306px" height="137px" xmlns:asp="#unknown">
<columns>
<asp:boundfield headertext="Rowid" datafield="Rowid" />
<asp:boundfield headertext="Name" datafield="Name" />
<asp:boundfield headertext="Marks" datafield="marks" />
</columns>
<footerstyle backcolor="#507CD1" font-bold="True" forecolor="White" />
<SelectedRowStyle BackColor="Teal" ForeColor="Maroon" Font-Bold="True" />
<pagerstyle backcolor="#2461BF" forecolor="White" horizontalalign="Center" />
<HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<alternatingrowstyle backcolor="White" />
<rowstyle backcolor="#EFF3FB" />
<editrowstyle backcolor="#2461BF" />
</asp:gridview>
<br />
<br />
<asp:textbox id="txtrowid" runat="server" style="z-index: 101; left: 365px; position: absolute; top: 251px" xmlns:asp="#unknown"></asp:textbox>
<asp:textbox id="txtname" runat="server" style="z-index: 102; left: 365px; position: absolute; top: 283px" xmlns:asp="#unknown"></asp:textbox>
<asp:textbox id="txtmarks" runat="server" style="z-index: 103; left: 365px; position: absolute; top: 315px" xmlns:asp="#unknown"></asp:textbox>
<asp:label id="Label1" runat="server" style="z-index: 107; left: 305px; position: absolute; top: 253px" xmlns:asp="#unknown">
Text="RowId"></asp:label>
<asp:label id="Label2" runat="server" style="z-index: 105; left: 303px; position: absolute; top: 287px" xmlns:asp="#unknown">
Text="Name"></asp:label>
<asp:label id="Label3" runat="server" style="z-index: 106; left: 306px; position: absolute; top: 318px" xmlns:asp="#unknown">
Text="Marks"></asp:label>
</div>
背后的代码:
Code Behind:
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
gvRank.DataSource = GetData();
gvRank.DataBind();
}
}
private DataTable GetData()
{
DataTable dt = new DataTable();
dt.Columns.Add("Rowid");
dt.Columns.Add("Name");
dt.Columns.Add("Marks");
DataRow dr = null;
for (int i = 0; i < 5; i++)
{
dr = dt.NewRow();
dr["RowId"] = "RowId" + i;
dr["Name"] = "Name" + i;
dr["Marks"] = "Marks" + i;
dt.Rows.Add(dr);
}
return dt;
}
protected void gvRank_SelectedIndexChanged(object sender, EventArgs e)
{
txtrowid.Text = gvRank.SelectedRow.Cells[1].Text;
txtname.Text = gvRank.SelectedRow.Cells[2].Text;
txtmarks.Text = gvRank.SelectedRow.Cells[3].Text;
}
}
谢谢
