使gridview中的一个单元格不可见？ [英] Make one cell in gridview invisible?

问题描述

大家好，


我有一个显示数据集和一些按钮的gridview。当这个数据集的某个

单元格为空时，我希望该行中的一个按钮可以看到
，否则该行中不会显示任何按钮。


我正在努力让这一整天工作，但它不会起作用。


我在rowCreated事件中试过这个。我能够找到正确的行

和此行中的单元格（作为数据行），但现在正确的gridview

行单元格应该可见。


这就是我现在所拥有的（C＃）：


protected void supplierFilesGrid_RowCreated（object sender，

GridViewRowEventArgs e ）如果（e.Row.RowType == DataControlRowType.DataRow）

{

DataRowView drView =（DataRowView）e.Row.DataItem;

DataRow drRow = drView.Row;


if（drRow [2] .ToString（）==" ; NEW"）

{

int i = e.Row.RowIndex; //

这很好用，之后我收到一个错误：

//grid.Rows [i] .Cells [1] .Visible = false; //

argumentOutOfRangeException ...

（发送者为GridView）.Rows [i] .Cells [1] .Visible =

false;

}

}

}


有没有人建议如何使这项工作？


提前致谢！

Hi all,

I have a gridview displaying a dataset and some buttons. When a certain
cell of this datasetrow is empty, I want a button in that row to be
visible, otherwise no button should be shown in that row.

I''m trying to make this work all day, but it''s not going to work.

I tried this in the rowCreated event. I am able to find the right row
and cell in this row (as a datarow), but now the right gridview
row-cell should be made visible.

This is what I have right now (C#):

protected void supplierFilesGrid_RowCreated(object sender,
GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DataRowView drView = (DataRowView)e.Row.DataItem;
DataRow drRow = drView.Row;

if (drRow[2].ToString() == "NEW")
{
int i = e.Row.RowIndex; //
this works fine, after this I get an error:
//grid.Rows[i].Cells[1].Visible = false; //
argumentOutOfRangeException...
(sender as GridView).Rows[i].Cells[1].Visible =
false;
}
}
}

Has anyone a suggestion how to make this work?

Thanks in advance!

Regards,
Jo

推荐答案

我相信你想要grid.ItemDataBound事件

I believe you want the grid.ItemDataBound event

你好，

也许我这样做，但在这次活动中该怎么做？

Hi,
Maybe I do, but what should I do within this event?

以下是我在本次活动中为您提供的代码片段。


e.Item.Cells.Item（ 4）.ToolTip = e.Item.Cells.Item（5）.Text

Here is a snippet of code I have in this event to get you started.

e.Item.Cells.Item(4).ToolTip = e.Item.Cells.Item(5).Text
