datagridview列显示索引无法正常工作 [英] datagridview column display index not working properly

问题描述

你好



i对datagridview有一点问题，我需要重新排序datagridview中的列







我在datagridview中加载了10列，其中5列是不可见的，我用简单的代码看不见







其余5我想按照displayindex属性订购



和这里是现在的事情



我输入代码



dg.AutoGenerateColumns = false;



dg.Columns [Column1] .Visible = false;

dg.Columns [Column2] .Visible = false;

dg.Columns [Column3] .Visible = false;

dg.Columns [Column4] .Visible = false;

dg.Columns [Column5]。 Visible = false;



dg.Column [Column6] .DisplayIndex = 1;

dg.Column [Column7] .DisplayIndex = 2;

dg.Column [Column8] .DisplayIndex = 3;

dg.Column [Column9] .DisplayIndex = 4;

dg.Column [Column10] .DisplayIndex = 5;



但是Column9到位3而不是4，而Column8到位8，他们改变了地方！

我甚至将其设置为将DisplayIndex-es保存到我的解决方案的Properties.Settings中，然后我将displayindexes读入每个列的文本框中以查看，并且其中有人认为Column9已经到位4但是IT不是，它是3月!!!!



我很困惑

帮助，任何人

Hello

i have a little issue with datagridview, I need to reorder columns in datagridview



I have 10 columns loaded into datagridview, 5 of them are invisible, which I made invisible in simple code



and the rest 5 I want to place in order with displayindex property

and here is the thing now

I put in code

dg.AutoGenerateColumns = false;

dg.Columns["Column1].Visible = false;
dg.Columns["Column2].Visible = false;
dg.Columns["Column3].Visible = false;
dg.Columns["Column4].Visible = false;
dg.Columns["Column5].Visible = false;

dg.Column["Column6].DisplayIndex = 1;
dg.Column["Column7].DisplayIndex = 2;
dg.Column["Column8].DisplayIndex = 3;
dg.Column["Column9].DisplayIndex = 4;
dg.Column["Column10].DisplayIndex = 5;

but Column9 gets on place 3 not 4, while Column8 gets on place 8, THEY CHANGE PLACES!!!
I even set it up to save DisplayIndex-es into Properties.Settings of my solution and then I read the displayindexes into textboxes for each column to see, and THERE IT SAYS Column9 is on place 4 but IT IS NOT, it's on 3!!!!

I am puzzled
help, anyone

推荐答案

由于不可见的列而出现问题。

设置了invisibe列的DisplayIndex。（即为两列提供DisplayIndex（按顺序可见和不可见）。

如下

Problem arises due to invisible columns .
set DisplayIndex of invisibe column also .(that is give DisplayIndex to both columns (visible and non visible in order).
as follows

dg.Columns["Column1"].Visible = false;
dg.Columns["Column2"].Visible = false;
dg.Columns["Column3"].Visible = false;
dg.Columns["Column4"].Visible = false;
dg.Columns["Column5"].Visible = false;

dg.Column["Column6"].DisplayIndex = 1;
dg.Column["Column7"].DisplayIndex = 2;
dg.Column["Column8"].DisplayIndex = 3;
dg.Column["Column9"].DisplayIndex = 4;
dg.Column["Column10"].DisplayIndex = 5;

dg.Column["Column1"].DisplayIndex = 6;
dg.Column["Column2"].DisplayIndex = 7;
dg.Column["Column3"].DisplayIndex = 8;
dg.Column["Column4"].DisplayIndex = 9;
dg.Column["Column5"].DisplayIndex = 10;

为网格提供正确的索引



by set property（index =number）

give proper indexing into grid

by set property (index="number")

//在EventHandler上写相同的代码如下所示：



MyForm.Shown + = new System.EventHandler（this.DlgEmpfListView_Shown）;



private void MyForm_Shown（object sender，EventArgs e）

{

//write same code on EventHandler Shown:

MyForm.Shown += new System.EventHandler(this.DlgEmpfListView_Shown);

private void MyForm_Shown(object sender, EventArgs e)
{

dg.Columns["Column1"].Visible = false;
dg.Columns["Column2"].Visible = false;
dg.Columns["Column3"].Visible = false;
dg.Columns["Column4"].Visible = false;
dg.Columns["Column5"].Visible = false;

dg.Column["Column6"].DisplayIndex = 1;
dg.Column["Column7"].DisplayIndex = 2;
dg.Column["Column8"].DisplayIndex = 3;
dg.Column["Column9"].DisplayIndex = 4;
dg.Column["Column10"].DisplayIndex = 5;

dg.Column["Column1"].DisplayIndex = 6;
dg.Column["Column2"].DisplayIndex = 7;
dg.Column["Column3"].DisplayIndex = 8;
dg.Column["Column4"].DisplayIndex = 9;
dg.Column["Column5"].DisplayIndex = 10;

}

}
