在datagridview中的单元格或列标题上单击 [英] Perform Click on a cell or column header in a datagridview

问题描述

我知道没有datagridview.performclick事件.
但是我有一个单元格是(0)和列(0)，需要
扫描文本框中的条形码，并以编程方式单击该列.
我已经搜索了Web和MS论坛，但找不到任何有效答案.
是否有可能在datagridview中的特定单元格或列上调用执行单击?这是用于vb net.当然，用C#回答也将有所帮助.

I know that there is no datagridview.performclick event.
But I have a cell that is (0) and column (0)and need to
scan a barcode in a textbox and have that column programatically clicked.
I have searched the web and MS forums but can''t find any working answers.
Is it possible at all to call a perform click on a specific cell or column in a datagridview? This is for vb net. Of Course an answer in C# would help too.

推荐答案

您可以通过一些JavaScript轻松实现.

制作3个隐藏字段:

You can do it easily with a bit of javascripting.

Make 3 hidden fields:

<input runat=server type=hidden id=inhAction />
<input runat=server type=hidden id=inhRow />
<input runat=server type=hidden id=inhColumn />

和一个javascript函数:

and a javascript function:

function cellClicked(row, column){
myForm.inhAction.value = "CELLCLICKED";
myForm.inhRow.value = row;
myForm.inhColumn.value = column;
myForm.submit();
}

并在gridview的RowDataBound事件中为每个
设置javascript调用 单元格:

and in the gridview''s RowDataBound event setup the javascript call for every
cell:

myCell.Attributes["onclick"]=String.Format("cellClicked({0},{1})",
myCellRow, myCellColumn);

当您单击一个单元格时，您将获得一个回发.您可以告诉
回传是由单元格单击inhAction引起的，您可以
从inhRow和inhColumn获取行号和列号.

如果有帮助，请 投票 和 接受答案 .

When you click a cell, you will get a postback. You can tell taht the
postback is caused by a cell click by looking in the inhAction and you can
get the row and the column numbers from the inhRow and inhColumn.
