我如何读取动态创建的文本框（gridview OnRowUpdating）

本文介绍了我如何读取动态创建的文本框（gridview OnRowUpdating）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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： { 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_3OnRowUpdating: 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 nullhere 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); } } } 这篇关于我如何读取动态创建的文本框（gridview OnRowUpdating）的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
