得到的GridView单元格文本框的值 [英] Get TextBox value from GridView cell
问题描述
我有一个包含模板字段的GridView。每个模板字段包含一个文本框。在GridView的最后一列包含SELECT命令字段。
在SELECT的点击,我想获得位于所选行的单元格文本框的值。
我试过:
((文本框)GridView1.Rows(e.Row.RowIndex).FindControl(TextBox1中))文本;
在Row_Updating事件,但它不工作。
我试过code在GridView控件的SelectedIndexChanged事件类似的变种,但它给错误:对象引用不设置到对象的实例
您需要寻找一个细胞里面,里面没有一排,试试这个:
<$p$p><$c$c>((TextBox)GridView1.Rows[e.Row.RowIndex].Cells[iCellIndex].FindControl(\"TextBox1\")).Text;您需要提供 iCellIndex
- 具有文本的单元格的指数
哦,用方括号来表示集合项目。
I have a GridView containing template fields. Each template field contains a TextBox. Last column of the GridView contains SELECT command field.
On click of SELECT, I want to get the value of TextBox located in a cell of the selected row.
I tried:
((TextBox)GridView1.Rows(e.Row.RowIndex).FindControl("TextBox1")).Text;
in Row_Updating event but it is not working.
I tried a similar variant of code in SelectedIndexChanged event of GridView but it gives error: Object Reference not set to an instance of an object.
You need to look inside of a Cell, not inside of a Row, try this:
((TextBox)GridView1.Rows[e.Row.RowIndex].Cells[iCellIndex].FindControl("TextBox1")).Text;
Where you need to supply iCellIndex
- index of the cell that has the textbox.
Oh and use square brackets to indicate collection item.
