Question

我需要从RowCommand事件中获取单元格的值，但该值不在GridView的PrimaryKeyNames参数中。

目前我有：

if (e.CommandName == "DeleteBanner")
        {
            GridViewRow row = gvCurrentPubBanner.SelectedRow;
            string BannerName = row.Cells[1].Text;

这不起作用（索引超出范围错误），我也尝试过：

    int index = Convert.ToInt32(e.CommandArgument);
GridViewRow row = gvCurrentBanners.Rows[index];

这不起作用，因为CommandArgument（横幅ID）不是行ID。

Answer 1

Dim row As GridViewRow = CType(CType(e.CommandSource, Control).NamingContainer, GridViewRow)

然后获取密钥或获取单元格并转换为数据控制域。

Dim id As Guid = GridView1.DataKeys(row.RowIndex).Value

Dim email As String = CType(row.Cells(2), DataControlFieldCell).Text

备注：这仅适用于Boundfields。

Answer 2

@Romil：您在C＃中的代码：

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
    int id = (int)GridView1.DataKeys[row.RowIndex].Value;
}

（LinkButton是模板字段中的按钮）。

Answer 3

试试这个......

GridViewRow gvRow = (GridViewRow)(((ImageButton)e.CommandSource).NamingContainer);
int rowIndex=gvRow.RowIndex

Answer 4

int index = Convert.ToInt32（e.CommandArgument）;

只有在Gridview中使用按钮时才能使用

<Columns>   
     <asp:ButtonField ButtonType="Button" Text="Save"  CommandName="Select" /> 
</Columns>

我不确定这是否正确，但它对我有用

Answer 5

    protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "Edit_Mob") {

        GridViewRow row = (GridViewRow (((ImageButton)e.CommandSource).NamingContainer);

        int RowIndex = row.RowIndex; // this find the index of row

        int varName1 = Convert.ToInt32(((Label)row.FindControl("lbl_mobile_id")).Text.ToString()); //this store the  value in varName1

        }
   }

Answer 6

if (e.CommandName == "EditDetails")
{
    mp1.Show();
    //LinkButton LnkEdit = (LinkButton)sender;
    GridViewRow gvrow = (GridViewRow)((Control)e.CommandSource).NamingContainer;
    Panel1.Visible = true;
    Uploaddocs.Visible = false;
    Label lblmobile = (Label)gvrow.FindControl("lblN_MobileNo") ;
    Label lblDeathDate = (Label)gvrow.FindControl("lblDEATHDT");
    Label lblCAUSEOFDEATH = (Label)gvrow.FindControl("lblCAUSEOFDEATH");
    Label lblPLACEOFDEATH = (Label)gvrow.FindControl("lblPLACEOFDEATH");
    // Label lblRemarks = (Label)gvrow.FindControl("lblpracticalcredits");
    Label lblBank = (Label)gvrow.FindControl("lblBank");
    Label lblBranch = (Label)gvrow.FindControl("lblBranch");
    Label lblIFSC = (Label)gvrow.FindControl("lblIFSC");
    txtMobile.Text = Convert.ToInt64(lblmobile.Text).ToString();       //May be BigInt
    txtdate.Text = lblDate.Text;
    //ddlReasons.SelectedIndex = Convert.ToInt32(lblCAUSEOFDEATH.Text);
    //ddlReasons.SelectedValue = lblCAUSEOFDEATH.Text;
    txtcausedeath.Text = lblCAUSEOFDEATH.Text;
    txtPlaceofdeath.Text = lblPLACEOFDEATH.Text;
    BindBank();
    ddlbank.SelectedItem.Text = lblBank.Text;             //Sdents
    txtAddrBank.Text = lblBranch.Text;
    txtIFSC.Text = lblIFSC.Text;
}
