使用按钮更新templateField中的文本框

it's my first time asking a question here in * so please bear with me. I am creating a webpage using asp.net, I have GridView with columns set as databound except 1 template field, within the template field is a textbox and a button. I want to update the value of the textbox using an outside button(a button in the same page, but outside the gridview), can anyone show/tell me how to do that?

这是我第一次在*中提问，所以请耐心等待。我正在使用asp.net创建一个网页，我将GridView的列设置为数据绑定，除了1个模板字段，模板字段中是一个文本框和一个按钮。我想使用外部按钮（同一页面中的按钮，但在gridview之外）更新文本框的值，任何人都可以显示/告诉我该怎么做？

GridView1 is the ID of the gridView,

GridView1是gridView的ID，

here is the templateField:

这是templateField：

<asp:TemplateField HeaderText="Template Field1">
    <ItemTemplate>
         <asp:TextBox runat="server" ID="textboxs">
         </asp:TextBox>
         <asp:Button runat="server" ID="buttons" Text="S"/>
     </ItemTemplate>
     <HeaderStyle Width="15px" />
     <ItemStyle Wrap="False" />
</asp:TemplateField>

<asp:Button ID="Button1" runat="server" onclick="Button1_Click1" Text="Button" />

here is the Code Behind:

这是守则背后：

protected void Button1_Click1(object sender, EventArgs e)
{
    GridViewCode.Rows[0].Cells[10].Text = "Some Text";
}

I think the problem is that the templatefield has a textbox and a button, please correct me if I am wrong.

我认为问题是templatefield有一个文本框和一个按钮，如果我错了，请纠正我。

BTW I can't remove the button in the templatefield, it has to be a textbox with a button. Thanks.

顺便说一下，我无法删除模板字段中的按钮，它必须是带按钮的文本框。谢谢。

3 个解决方案

#1

protected void Button1_Click1(object sender, EventArgs e)
{
    // First bind you grid again over here other wise it will lost data

    GridView1.DataSource = you List of Objects or DataTable;
    GridView1.DataBind();

    foreach (GridViewRow gvr in GridView1.Rows)
    {
        if (gvr.RowType == DataControlRowType.DataRow)
        {
            // to fill all text boxes
            TextBox textboxs = gvr.FindControl("textboxs") as TextBox;
            textboxs.Text = "You text";


            // to fill specific text box
            // use gvr.DataItem to check aging specific data item using if and then
            // textboxs.Text = "You text";
        }
    }
}

You can use a code like this:

    for (int i = 0; i < GridView.Rows.Count; i++)
    {
        GridViewRow gvr = GridView.Rows[i];
        Textbox txtBox= (Textbox)gvr.Cells[0].FindControl("textbox_id");
        txtBox.Text = "Your new text here";
    }

This will replace the text box of each row and you can impose conditions for replacing it in specific rows.

这将替换每行的文本框，您可以强制条件在特定行中替换它。

Without further code from you, something along the lines of:

没有你的进一步代码，有些东西：

protected void Button1_Click1(object sender, EventArgs e)
{
   TextBox textboxs = GridView.Rows[2].FindControl("textboxs");
   textboxs.Text = "New Text Here";
}

where index 2 is the row index of your gridview's databound data

其中index 2是gridview的数据绑定数据的行索引

#1

protected void Button1_Click1(object sender, EventArgs e)
{
    // First bind you grid again over here other wise it will lost data

    GridView1.DataSource = you List of Objects or DataTable;
    GridView1.DataBind();

    foreach (GridViewRow gvr in GridView1.Rows)
    {
        if (gvr.RowType == DataControlRowType.DataRow)
        {
            // to fill all text boxes
            TextBox textboxs = gvr.FindControl("textboxs") as TextBox;
            textboxs.Text = "You text";


            // to fill specific text box
            // use gvr.DataItem to check aging specific data item using if and then
            // textboxs.Text = "You text";
        }
    }
}

You can use a code like this:

    for (int i = 0; i < GridView.Rows.Count; i++)
    {
        GridViewRow gvr = GridView.Rows[i];
        Textbox txtBox= (Textbox)gvr.Cells[0].FindControl("textbox_id");
        txtBox.Text = "Your new text here";
    }
