我如何读取动态创建的文本框（gridview OnRowUpdating） [英] How can I read a dynamically created textbox (gridview OnRowUpdating)

问题描述

 < asp：GridView ID =GridView1runat =server> 
 
< asp：TemplateField HeaderText =TokenSortExpression =TokenHeaderStyle-Width =100px> 
< ItemTemplate> 
 
< / ItemTemplate> 
< / asp：TemplateField> 
 
< / asp：GridView> 
  

更新：

  ctl00_ContentPlaceHolder1_tabControl_tabUsers_MyControl1_gv_ctl02__token0_3 
页面的源代码是我所看到的文本框的id。  

OnRowUpdating：

  TextBox _token = gvOrg.Rows [e.RowIndex] .Cells [7] .FindControl（_ token+ e.RowIndex +_+ rowId）作为TextBox; 
  

更新结束：



这里是我的代码：

< pre $ protected void gv_RowUpdating（object sender，GridViewUpdateEventArgs e）
{
for（int rowId = 0; rowId< 5; rowId ++）
{$ b Text TextBox _token = gvOrg.Rows [e.RowIndex] .Cells [7] .FindControl（_ token+ rowId）作为TextBox;



protected void gv_RowDataBound（object sender，GridViewRowEventArgs e）
{
if（（e.RowState ==（DataControlRowState。编辑| DataControlRowState.Alternate））||（e.RowState == DataControlRowState.Edit））
{

if（e.RowType == DataControlRowType.DataRow）
$ b {
for（int rowId = 0; rowId< 5; rowId ++）
{
TextBox txtBox = new TextBox（）;
txtBox.ID =_token+ rowId;
txtBox.Text =token+ rowId;
e.Row.Cells [7] .Controls.Add（txtBox）;



$ div $解析方案

是我如何解决这个问题：而不是创建rowdatabound我创建的RowCreated，希望这将有助于其他人。

  protected void gridviwe1_RowCreated（object sender，GridViewRowEventArgs e）
 {
 
 if（e.RowType == DataControlRowType.DataRow）
 {
 for（int rowId = 0; rowId< 5; rowId ++）
 {
 TextBox txtBox = new TextBox（）; 
 txtBox.ID =_registration+ e.Row.RowIndex +_+ rowId; 
 txtBox.Text =_registration+ e.Row.RowIndex +_+ rowId; 
 e.Row.Cells [7] .Controls.Add（txtBox）; 
} 
} 
} 
  




 <asp:GridView ID="GridView1" runat="server"  >

<asp:TemplateField HeaderText="Token" SortExpression="Token" HeaderStyle-Width="100px">
                    <ItemTemplate>                       

                    </ItemTemplate> 
                </asp:TemplateField>

</asp:GridView> 

update:

after i view the source code of the page thsi is what i see the id of a textbox that i have created dynamic.

ctl00_ContentPlaceHolder1_tabControl_tabUsers_MyControl1_gv_ctl02__token0_3

OnRowUpdating:

 TextBox _token = gvOrg.Rows[e.RowIndex].Cells[7].FindControl("_token " + e.RowIndex + "_" + rowId) as TextBox;

Update end:

i am adding few textbox dynamic in OnRowDataBound and whe i try getting the value then i am getting null

here is my code:

 protected void gv_RowUpdating(object sender, GridViewUpdateEventArgs e)
        {    
            for (int rowId = 0; rowId < 5; rowId++)
            {
                TextBox _token = gvOrg.Rows[e.RowIndex].Cells[7].FindControl("_token" + rowId) as TextBox;
             }      
        }

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if ((e.Row.RowState == (DataControlRowState.Edit | DataControlRowState.Alternate)) || (e.Row.RowState == DataControlRowState.Edit))
            {

                if (e.Row.RowType == DataControlRowType.DataRow)
                {                                             
                    for (int rowId = 0; rowId < 5; rowId++)
                    {    
                        TextBox txtBox = new TextBox();
                        txtBox.ID = "_token" + rowId;
                        txtBox.Text = "token" + rowId;
                        e.Row.Cells[7].Controls.Add(txtBox);  
                    } 
}

解决方案

here is how i able to fix the problem: instead of creating in rowdatabound i am creating on RowCreated, hope this will help others.

 protected void gridviwe1_RowCreated(object sender, GridViewRowEventArgs e)
        {

                if (e.Row.RowType == DataControlRowType.DataRow)
                {
                    for (int rowId = 0; rowId < 5; rowId++)
                    {
                        TextBox txtBox = new TextBox();
                        txtBox.ID = "_registration" + e.Row.RowIndex + "_" + rowId;
                        txtBox.Text = "_registration" + e.Row.RowIndex + "_" + rowId;
                        e.Row.Cells[7].Controls.Add(txtBox);
                    }
                }
            }
