Question

我想在单击中编辑gridview中的记录。我的gridview放在更新面板中。有一个搜索文本框，当我在搜索文本框中输入任何内容时，＆＃34; txt_Search_TextChanged＆＃34;触发事件并在数据库中搜索该文本，并获取该特定记录并绑定到网格。

现在我的问题是：如果我点击网格的编辑按钮而不搜索，则会触发事件。但是如果我搜索任何记录然后我点击编辑按钮，则需要2次点击才能给出结果。我为textbox写了一个脚本，如下所示：

enter code here
                <script>
            function RefreshUpdatePanel() {
            __doPostBack('<%= txt_Search.ClientID %>', '');

     };

下面是aspx代码

    <tr>
        <td align="center">
            <div style="border-width: 2px; border-style: solid; border-color: #FDAC4C; width: 95%; border-radius: 10px;">

下面是用于划船的cs代码

    try

        tab0.Enabled = false;
        tab1.Enabled = true;

        txtCoolType.Text = CoolingName.Text.Trim();

        btnsave.Text = "Update";
        ViewState["CoolingCode"] = CoolingCode.Text;
        TabContainer_Item.ActiveTabIndex = 1;

        Session["CoolingCode"] = CoolingCode.Text;
        this.fu1.BindGridDoc();
    }
    catch (Exception ex)
    {

        Master.ErrorMessage(ex.Message);
    }
}

{
    try
    {
        DataSet ds = gn.ExecuteDataset("Search_CoolingType", txt_Search.Text.Trim());

        ViewState["CoolingTypeData"] = ds.Tables[0];
        if (ds.Tables[0].Rows.Count == 0)
        {
            FillEmptyGrid();

        }
        else
        {

            grd_Master.DataSource = ds;
            grd_Master.DataBind();

        }
    }

    catch (Exception ex)
    {
        Master.ErrorMessage(ex.Message);
    }
}

Answer 1

您需要确保网格具有焦点。初始点击可能只是将焦点设置在网格上，然后它会在开始编辑时看到第二次点击。

ActiveControl = grd_Master;事件结束时的简单txt_Search_TextChanged应该可以解决问题。

gridview编辑模式不会在单击时触发
