如何获取Gridview动态创建的项目模板的价值 [英] how to get value of dynamic created item template of Gridview

问题描述

我已经动态创建了一个只有一行的gridview，并且还动态创建了项目模板，并设置了行硬核的值

当我尝试获取row的值时，我什么也没得到

所以我如何获得gridview动态创建的项目模板的值


我用于创建itemtemplate的代码是

  foreach (DataColumn col  in  dt.Columns中的列)
            {
                // 声明绑定字段并为绑定字段分配内存.
                TemplateField bfield = 新 TemplateField();
 
                // 初始化DataField值.
                bfield.HeaderTemplate = 新 GridViewTemplate(ListItemType.Header，col.ColumnName);
 
                // 初始化HeaderText字段值.
                bfield.ItemTemplate = 新 GridViewTemplate(ListItemType.Item，col.ColumnName);
 
                // 将新创建的绑定字段添加到GridView.
                GrdDynamic.Columns.Add(bfield);
            } 

解决方案

在获取值之前必须绑定gridview

如果通过按钮获取值，请单击

然后添加GrdDynamic.DataBind();在click事件中，然后检索tha值

i have created gridview with one row dynamically and created item template also dynamically and setting a value of row hardcore

when i trying to get the value of row so i didn''t get anything

so how can i get the value of dynamic created item template of gridview


my Code for creating itemtemplate is

foreach (DataColumn col in dt.Columns)
            {
                //Declare the bound field and allocate memory for the bound field.
                TemplateField bfield = new TemplateField();
 
                //Initalize the DataField value.
                bfield.HeaderTemplate = new GridViewTemplate(ListItemType.Header, col.ColumnName);
 
                //Initialize the HeaderText field value.
                bfield.ItemTemplate = new GridViewTemplate(ListItemType.Item, col.ColumnName);
 
                //Add the newly created bound field to the GridView.
                GrdDynamic.Columns.Add(bfield);
            }

解决方案

You have to bind your gridview before getting the values

If you getting the values on a button click

then add GrdDynamic.DataBind(); in the click event and then retrieve tha values
