Gridview标签文字的下拉列表问题 [英] Dropdownlist Problem with Gridview Lable text

问题描述

你好朋友，

我在sample.aspx中有一个gridview，其中包含名称，移动拾取区域等，并在Gridview中具有更新"链接按钮.

当我单击linkbutton时，这些值必须保存在相应的控件中.
启用了领取区的自动回传属性，并且下拉列表在
中进行了绑定 (！ispostback)page_load事件.

问题出在以下地区:

//Under row command:
   if (e.CommandName == "update")
{
 int index = Convert.ToInt32(e.CommandArgument) % GridView1.PageSize;
                GridViewRow row = GridView1.Rows[index];
//----------
//----------
Label lblPickuparea = (Label)row.FindControl("Label7");
ddlParea.SelectedItem.Text= lblPickuparea.Text;//Here selectitemtext value is 3

 ddlParea.SelectedValue = ddlParea.Items.FindByText(lblPickuparea.Text).Value;//here selected value is -1
}

所以我想将selectedvalue作为selecteditem.text值.
基于此，我必须绑定另一个下拉列表.

我已经完成下拉列表和页面的enableviewstate ="true".

请帮帮我.

谢谢大家.

解决方案

ddlParea.SelectedValue = ddlParea.Items [ddlParea.Items.IndexOf(ddlParea.Items.FindByText(lblPickuparea.Text))].Value;

<您是否确定要使用FindByText? 3似乎没有任何领域.我想，您在FindByText和FindByValue之间感到困惑.如果您共享下拉菜单的HTML，我相信您会得到正确的答案.


为了清楚起见，您可以按以下方式使用它

 ddlParea.SelectedValue = lblPickuparea.Text;
// 或
ddlParea.Items.FindByValue(lblPickuparea.Text).Selected =  true ; 

Hello friends,

i have a gridview in sample.aspx which contains name, mobile pickuparea etc. and Update linkbutton in Gridview.

when i click on linkbutton these values have to be saved in the respective controls.
Autopostback property of pickuparea is enabled and dropdownlists are binded in
(!ispostback) of the page_load event.

the problems comes with the follwoing area:

//Under row command:
   if (e.CommandName == "update")
{
 int index = Convert.ToInt32(e.CommandArgument) % GridView1.PageSize;
                GridViewRow row = GridView1.Rows[index];
//----------
//----------
Label lblPickuparea = (Label)row.FindControl("Label7");
ddlParea.SelectedItem.Text= lblPickuparea.Text;//Here selectitemtext value is 3

 ddlParea.SelectedValue = ddlParea.Items.FindByText(lblPickuparea.Text).Value;//here selected value is -1
}

So i want to get the selectedvalue as the selecteditem.text value.
Based on this i have to bind another dropdownlist.

I have done enableviewstate="true" of dropdownlist and page.

Please do help me.

Thanking you all.

Replace your last line of code with below.

ddlParea.SelectedValue = ddlParea.Items[ddlParea.Items.IndexOf(ddlParea.Items.FindByText(lblPickuparea.Text))].Value;

Are you sure you want to use FindByText? 3 doesn''t seem like any area. I guess, you are confused between FindByText and FindByValue. If you share HTML of your dropdown, I''m sure you''ll get proper answer.

[Edit]
To make it clear, you can use it in following way

ddlParea.SelectedValue = lblPickuparea.Text;
//or
ddlParea.Items.FindByValue(lblPickuparea.Text).Selected = true;
