【问题描述】：

我想disable gridview 在gridview 内的按钮单击上的行。为此，我编写了以下代码。

protected void btnPayGenInvoice_Click(object sender, EventArgs e)
{
    if (strMode == "M")
    {
        Button btn = (Button)sender;
        GridViewRow row = (GridViewRow)btn.Parent.Parent;
        row.Enabled = false;
    }
}

但我收到错误

无法将“Obout.Grid.GridTemplate”类型的对象转换为“System.Web.UI.WebControls.GridViewRow”类型。

请告诉我这里出了什么问题

更新

在GridViewRow row = (GridViewRow)btn.Parent.Parent; 行出现错误

更新 2

按钮点击事件的代码。

protected void GetRowDataPay(object sender, CommandEventArgs e)
{
    int rowIndex = int.Parse(e.CommandArgument.ToString());

    Hashtable dataItemPay = GridPayInfo.Rows[rowIndex].ToHashtable() as Hashtable;

    if (ObjPriCon.State != ConnectionState.Open)
    {
        ObjPriCon.Open();
        OracleCommand cmdMkeyPay = new OracleCommand("select XXCUS.XXACL_LAND_PURC_INV_VIEW_MKEY.nextval from dual", ObjPriCon);
        string MkeyPay = Convert.ToString(cmdMkeyPay.ExecuteOracleScalar());

        OracleCommand cmdORGID = new OracleCommand("select XXCUS.XXACL_LAND_PURC_INV_VIEW_MKEY.nextval from dual", ObjPriCon);
        string ORG_IDKEY = CF.ExecuteScaler2("select ORGANIZATION_ID,ORGANIZATION_NAME from apps.xxacl_company_mst where ORGANIZATION_NAME = '" + txtCompName.Value + "'");

        string strExpQuery = "insert into XXCUS.XXACL_LAND_PURC_INVOICE_VIEW (MKEY,REF_PURCHASE_ID,REF_SR_NO, " +
                         "REF_PURHCASE_TYPE,ORG_ID,PROJECT_ID,TALUKA_ID,VILLAGE_ID,SURVEY_AREA_7_12,DOC_NO,INVOICE_ID,INVOICE_NUM,VENDOR_ID, " +

                         "'" + Request.QueryString["userid"].ToString() + "', " + "NULL" + "," + "NULL" + ")";
        OracleCommand cmdQuery = new OracleCommand(strExpQuery, ObjPriCon);
        cmdQuery.ExecuteNonQuery();
        ObjPriCon.Close();
        ScriptManager.RegisterStartupScript(this, this.GetType(), "Success", "alert('Payment Invoice inserted into table successfully');", true);
    }
}

【问题讨论】：

您要禁用哪一行。 Yiu 需要获取您想要禁用的选定行并将其传递给代码。那么您可以禁用该行。
@YashveerSingh：是的，我想禁用单击按钮的行。
好的，所以您必须有一个选定的行事件，当您在该事件上选择该记录时将触发该事件，您可以执行此操作。
我将更新我的问题中的事件代码。请让我知道如何获取选定的行并禁用它。
好的，我会努力的

【解决方案1】：

您应该使用 rowIndex 值来获取 gridviewrow，然后像这样禁用它

if (GridPayInfo.Rows[rowIndex] != null) 
{ 
  GridPayInfo.Rows[rowIndex].Enabled = false; 
}

【讨论】：

protected void btnPayGenInvoice_Click(object sender, EventArgs e) { if (GridPayInfo.Rows[rowIndex] != null) { if (strMode == "M") { Button btn = (Button)sender; GridViewRow.Rows[rowIndex].Enabled = false; } } }
感谢 Yashveer，这个运行得非常好..！！需要知道如何禁用删除部分。
我还有很多其他问题，稍后会发布并让您知道。谢谢现在..祝你有美好的一天
嗨@nad，没问题，请告诉我这个问题，我会尽力回答
