如何在动态创建的gridview中触发按钮事件 [英] How to fire the button event in gridview created dynamically

问题描述

Hi Geeks，



我有一个webcontrols的gridview（文本框，页脚按钮）。动态地，我需要通过以下代码创建任意数量的网格视图。但只创建了1个gridview。而且问题是按钮事件没有解雇

Hi Geeks,

I've a gridview with webcontrols(Textbox,Button in footer). Dynamically I need to create any number of gridviews by the following code. But only 1 gridview is created. And also the problem is the button event is not firing

public void btn_Click(object sender, EventArgs e)
    {
        GridView gv = new GridView();
        gv.ID = sender.ToString();
    }

在课堂上。怎么解雇这个事件？这是我用来创建gridview的代码。

inside the class. How to fire this event? This is the code I used to create gridview.

protected void btnAddGrid_Click(object sender,EventArgs e)
{
    int count = Convert.ToInt32(Session["count"]);
    DataTable dt=(DataTable)ViewState["CurrentTableforCommonDetails"];
    GridView gv = new GridView();
    gv.ID = "GridView" + count;
    gv.AutoGenerateColumns = false;
    if (dt.Rows.Count > 0)
    {
        for (int i = 0; i < dt.Columns.Count; i++)
        {
            TemplateField tmpfld = new TemplateField();
            tmpfld.HeaderText = dt.Columns[i].ColumnName.ToString();
            tmpfld.ItemTemplate =new DynamicTemplateField();
            if (i == 0)
            { 
                tmpfld.FooterTemplate = new DynamicTemplateField1();
            }
            gv.Columns.Add(tmpfld);
        }
    }
    gv.Visible = true;
    gv.ShowHeaderWhenEmpty = true;
    gv.ShowFooter = true;
    placegridview.Controls.Add(gv);
    gv.DataSource = dt;
    gv.DataBind();

    count++;
    Session["count"] = count;
}

public class DynamicTemplateField : ITemplate
{
    public void InstantiateIn(System.Web.UI.Control container)
    {
        //define the control to be added , i take text box as your need
        System.Web.UI.WebControls.TextBox txt1 = new System.Web.UI.WebControls.TextBox();
        txt1.ID = "txt1";
        txt1.Width = 50;
        container.Controls.Add(txt1);
    }
}

public class DynamicTemplateField1 : ITemplate
{
    public void InstantiateIn(System.Web.UI.Control container)
    {
        //define the control to be added , i take text box as your need
        System.Web.UI.WebControls.Button btn = new System.Web.UI.WebControls.Button();
        btn.ID = "btn1";
        btn.Click += new EventHandler(btn_Click);
        btn.UseSubmitBehavior = false;
        btn.Text = "Add New";
        container.Controls.Add(btn);
    }
    public void btn_Click(object sender, EventArgs e)
    {
        GridView gv = new GridView();
        gv.ID = sender.ToString();
    }

}

从ASP动态添加和删除行.NET GridView [ ^ ]

尝试使用CellContentClick

Instead of using the button click event,try using CellContentClick

this.dataGrid1.CellContentClick += new DataGridViewCellEventHandler(dataGrid1_CellContentClick);

然后在事件处理程序中，询问它是否是您的按钮单元格

And then in the event handler,ask if it's your button cell

void dataGrid1_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            
            if (e.ColumnIndex == this.dataGrid1.Columns["ButtonColumn"].Index )
            {
                //Do your staff
            }
        }

编辑：那是winforms。在asp.net中，请参阅此 http://msdn.microsoft.com /en-us/library/vstudio/bb907626(v=vs.90).aspx [ ^ ]希望有所帮助。

That was for winforms. In asp.net refer this http://msdn.microsoft.com/en-us/library/vstudio/bb907626(v=vs.90).aspx[^] Hope it helps.
