Question

如何在网格视图的行命令中找到控件？

Answer 1

实际上GridViewCommandEventArgs中没有Row，因此您需要从命令源命名容器中获取行

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

然后你就可以使用

了

TextBox myTextBox = row.FindControl("MyTextBoxId") as TextBox;

希望这有帮助！

Answer 2

如果您使用LinkButton

private void Download(object sender, TappedRoutedEventArgs e)
        {
            // Create a WriteableBitmap with height and width same as that of Layoutroot
            WriteableBitmap bmp = new WriteableBitmap(480, 696);

            //Render the layoutroot element on it
            bmp.Render(Scrshot, null);
            bmp.Invalidate();


            //Save the image to Medialibrary

            //create a stream of image
            var ms = new MemoryStream();
            bmp.SaveJpeg(ms, 480, 696, 0, 100);
            ms.Seek(0, SeekOrigin.Begin);


            //every path must be unique
            var filePath = "myfile" + DateTime.Now.ToString();

            //Remember to include Medialib capabilty from WMAppManifest.xml for acessing the Medialibrary
            var lib = new MediaLibrary();
            lib.SavePicture(filePath, ms);

            MessageBox.Show("Saved in your media library!", "Done", MessageBoxButton.OK);
        }

Answer 3

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

Label lblProdId = (Label)row.FindControl(“lblproductId”);

Answer 4

如果你想在行命令中找到一个控件使用

controlname controlId=(controlname)e.FindControl("controlId");

例如，如果您想找到ID lbl 的标签，请使用..

Label lbl = (Label)e.Row.FindControl("lbl");

Answer 5

您可以使用＆＃34; CommandArgument＆＃34;在你的控制中使用＆＃34; CommandName＆＃34;。这里有两个论点：

string[] arg = e.CommandArgument.ToString().Split(';');
int index = Convert.ToInt16(arg[0]);
string idinterlocuteur = arg[1];

然后在你的代码中你可以获得参数：

CheckBox Check1 = GridView1.Rows[index].FindControl("MyCheckboxinrow") as CheckBox;

现在你争论找到你的控件：

{
  “kind”: “clms#course”,
  “id”: long,
  “course-name”: string,
  “course-icon”: string,
  “product-name”: string,
  “product-icon”: string,
  “_links”: {
    “self”: {“href” : string}, 
    “unitlist”: {“href” : string} // This is a link to list of units for the course.
  }
}

Answer 6

如果您在gridview itemtemplate中使用usercontrols，那么((Control)e.CommandSource).NamingContainer可能不会返回您的gridviewrow。

在这种情况下，我使用以下代码获取当前行：

var c = ((Control) e.CommandSource).NamingContainer;
while (c.GetType() != typeof(GridViewRow))
{
    c = c.Parent;
}
var currentRow = (GridViewRow) c;

它不漂亮，但它确实有效。

                    <i class="ace-icon fa fa-close"></i></asp:LinkButton>
                    </div>
            </EditItemTemplate>
            <ItemTemplate>
                <div class="btn-group">

        </asp:TemplateField>


 if (e.CommandName == "UpdateStat")
        {
            HiddenField IDHiddenField=(HiddenField)GridView1.Rows[Convert.ToInt32(e.CommandArgument)].FindControl("IDHiddenField");
            TextBox CurrentStatDesTextBox=(TextBox)GridView1.Rows[Convert.ToInt32(e.CommandArgument)].FindControl("CurrentStatDesTextBox");}

Answer 8

GridViewRow gvr =（GridViewRow）（（Control）e.CommandSource）.NamingContainer; int rowIndex = gvr.RowIndex;

        string Cat_name = (GridView1.Rows[rowIndex].FindControl("TxtName") as TextBox).Text;

Answer 9

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)    
{

GridViewRow gvr = (GridViewRow)((Control)e.CommandSource).NamingContainer;
int rowIndex = gvr.RowIndex;

string Cat_name = (GridView1.Rows[rowIndex].FindControl("TxtName") as TextBox).Text;

}

Answer 10

 GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);                    
                    HiddenField hdMeasurementId = ((HiddenField)row.FindControl("hdMeasurementId"));

Answer 11

GridViewCommandEventArgs不支持该行，因此请使用命名容器来查找控件。

  protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
       Control ctrl = e.CommandSource as Control;  
       if (ctrl != null)
       {
           GridViewRow gvRow = ctrl.Parent.NamingContainer as GridViewRow; 
           Label slno = (Label)gvRow.FindControl("slno");  // Find Your Control here
           TextBox txtno = (TextBox)gvRow.FindControl("txtno");  // Find Your Control here
           // Your work start here
       }
    }
