从gridview中的选定行显示外部文本框中的数据 [英] show data in outside textbox from selected row in gridview

问题描述

我有一个网格视图。

I having a grid view.

<asp:GridView ID="grdPurchaseBill" runat="server" CssClass="grdcls grdstyle" ShowHeader="true" AutoGenerateColumns="false" ShowFooter="true" AllowSorting="true" ShowHeaderWhenEmpty="true" EmptyDataText="No Records Found">
<Columns>
 <asp:CommandField ShowDeleteButton="True" ButtonType="Link" DeleteImageUrl="~/Images/trash.png" FooterStyle-BorderStyle="None" ItemStyle-BorderStyle="None" HeaderText="Action"> </asp:CommandField>
</asp:CommandField>
<asp:BoundField DataField="AcctId" HeaderText="Accout ID" />
<asp:BoundField DataField="CreditToAccount" />
<asp:BoundField DataField="Amount" HeaderText="Amount" />
<asp:BoundField DataField="Vat" HeaderText="VAT%" />
<asp:BoundField DataField="BasicAmount" HeaderText="Basic Amt." />
</Columns>
</asp:GridView>

和cs代码是：

and cs code is:

protected void grdPurchaseBill_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            try
            {
                int index = Convert.ToInt32(e.CommandName.ToString());
                string accidno = grdPurchaseBill.Rows[index].Cells[2].Text.ToString();
                txtCreditToAcc.Text = accidno;
                txtamount.Text = grdPurchaseBill.Rows[index].Cells[3].Text.ToString();
                txtVat.Text = grdPurchaseBill.Rows[index].Cells[4].Text.ToString();
                txtBasicAmount.Text = grdPurchaseBill.Rows[index].Cells[5].Text.ToString();
            }
            catch (Exception ex)
            {
            }
        }

当我点击网格行时，行命令有火，我看到值被分配给文本框（使用断点）。但是当我在页面上看到文本框是空的。我厌倦了。 PLZ帮助

谢谢

推荐答案

所以你需要将另一个布尔参数传递给你的函数是注册商进行事件验证

so you need to pass another one boolean parameter to your function is registrar for event validation

e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(grdjournalvoucher, "

+ e.Row.RowIndex， false ）;

我想你应该使用



Convert.ToInt32（e.CommandArgument）而不是 CommandName 来获取Row索引值。尝试并恢复特定错误（如果有的话）。

I think you should use

Convert.ToInt32(e.CommandArgument) instead of CommandName to fetch the Row index value. Try it and revert with the specific errors if any.
