如何在webdatagrid中获取文本框的值

Question

我总是得到一个空值的文本框从网格。下面是我的点击事件代码:

            foreach (GridRecord row in wdgTroubleshootCreateEdit.Rows)
            {
                int workflowCATParameterId = Convert.ToInt32(row.Items[0].Value);
                TextBox workflowCATParameterValue =
                    (TextBox)row.Items[value].FindControl("txtWorkflowCATParameterValue");

workflowCATParameterValue.text总是null

我使用最新的服务版本11.2。我试着:

 protected void Button2_Click(object sender, EventArgs e)
{
   TextBox text = WebDataGrid1.Rows[0].Items[0].FindControl("TextBox1") as TextBox;
   var rrr = text.Text;
}

，它工作得很好:)我的网格被称为WebDataGrid1和第一列被模板化包含TextBox命名为Text:

<ig:WebDataGrid ID="WebDataGrid1" runat="server" Height="350px" Width="400px">
    <Columns>
        <ig:TemplateDataField Key="TemplateField_0">
            <header text="TemplateField_0" />
            <ItemTemplate>
                <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
            </ItemTemplate>

        </ig:TemplateDataField>
    </Columns>
    <Behaviors>
        <ig:EditingCore>
            <behaviors>
                <ig:CellEditing>
                </ig:CellEditing>
            </behaviors>
        </ig:EditingCore>
        <ig:Activation>
        </ig:Activation>
    </Behaviors>
    <Templates>
        <ig:ItemTemplate ID="WebDataGrid1Template1" runat="server" 
            TemplateID="Template1">
        </ig:ItemTemplate>
    </Templates>
</ig:WebDataGrid>

我用ie9测试了一下:)

通过javascript你可以这样做:

function OnExitedEditMode(sender,e){
    var row = e.getCell().get_row();
    var text = row.get_cellByColumnKey("YourDataKey").get_value();
    ....
}

在你的WebDataGrid中你需要输入这个:

<Behaviors>
    <ig:EditingCore>
        <Behaviors>
            <ig:CellEditing EditModeActions-MouseClick="Single">
                <ColumnSettings>
                    ...
                </ColumnSettings>
                <CellEditingClientEvents ExitedEditMode="OnExitedEditMode" />
            </ig:CellEditing>
        </Behaviors>
    </ig:EditingCore>
</Behaviors>
