无法访问GridView单元格值 [英] Unable to access gridview cell value

问题描述

大家好，

protected void update_Status_Click(object sender, EventArgs e)
    {
        
        List<int> id = new List<int>();
       
        foreach (GridViewRow row in GridView1.Rows) 
        {
            int i = row.RowIndex;
        
            CheckBox cb = (CheckBox)row.FindControl("SelectCashout");
 
            if (cb != null && cb.Checked) 
            {
                

                if (GridView1.Rows[i].Cells[2].Text == "Requested")
                {
                    int x = Convert.ToInt32(GridView1.Rows[i].Cells[0].Text);
                    id.Add(x);
                }
            } 
        } 
    }

当我调试它时，我得到"GridView1.Rows [i] .Cells [2] .Text"值为空字符串.

这不是Gridview事件，它是gridview之外的按钮事件.
我尝试了row.Cells[2].Text它没有帮助.目前，gridview显示10行，所有列中的所有数据.

它不是Gridview上的编辑/更新"按钮.
我为用户提供了选择他要更新的行的选项.
根据他通过复选框的选择，我只需要更新gridview中的一个单元格值并收集表中该行的主键，以便在后端更新数据源(我未包含的代码)
希望你能理解.更新一个单元格值不是强制性的，因为我正在更新数据源，并且可以重新绑定它.收集该行的主键(数据源表)是
"GridView1.Rows [i] .Cells [0] .Text"对于更新数据库很重要.



我在这里想念什么?任何帮助，谢谢

When I debug it I am getting "GridView1.Rows[i].Cells[2].Text" value as empty string.

This is not a Gridview event, it is button event out side the gridview.
I tried row.Cells[2].Text it doesn''t help. At the moment gridview showing 10 rows with all the data in all the columns.

It''s not Edit/Update button on Gridview.
I am giving option to the user to select which rows he wants to update.
Based on his selection through checkbox I have to update just one cell value in the gridview and collect primary key of that row in the table so I will update datasource at backend(That code I haven''t included)
Hope you understood. updating one cell value is not mandatory because I am updating datasource and I can rebind it. Collecting that row''s Primary key(Datasource Table''s) is
"GridView1.Rows[i].Cells[0].Text" important to update database.



What am I missing here? any help thanks

推荐答案

下面的代码可能会帮助您

Below code may help you

LinkButton lbtnID= (LinkButton)sender;
int index = ((GridViewRow)lbtnID.NamingContainer).RowIndex;

Label lblID= ((Label)gdDiscount.Rows[index].Cells[1].FindControl("lblID"));
int  value= Convert.ToInt32(lblID.Text.ToString());

将此链接写在gridview的内部链接按钮中..希望这会给您一些想法..让我知道您是否仍然有问题

Write this inside link button in gridview.. Hope this will give you some idea..Let me know if you have still problem
