我能想到做到的所有方面,这显得非常的hackish。什么是做正确的方式,或者至少是最常见?
我检索从LINQ到SQL查询一组图像和数据绑定它和其他一些数据转发器。我需要一个文本框添加到中继器的每个项目,这将让用户改变每个图像的标题,很相似到Flickr。
如何访问文本框的Repeater控件,并知道哪些形象文本框是属于?
下面是中继器控制会是什么样子,有一个提交按钮,这将更新所有的图像行LINQ到SQL:

这code工作
只要确保你不要被绑定之外吹你的价值观的路程,如果(!Page.IsPostBack)像我..哎呀。
< ASP:直放站ID =Repeater1=服务器> <&ItemTemplate中GT; < DIV CLASS =itemBox> < DIV CLASS =imgclass> <标题='<%#的eval(姓名)%>' HREF ='<%#的eval(路径)%GT;'相对=画廊> < IMG ALT ='<%#的eval(姓名)%>' SRC ='<%#的eval(路径)%GT;' WIDTH =260/> &所述; / A> < / DIV> < ASP:文本框ID =TextBox1的WIDTH =230px=服务器>< / ASP:文本框> < / DIV> < / ItemTemplate中>< / ASP:直放站>和提交点击:
保护无效的button1_Click(对象发件人,EventArgs的发送){ 的foreach(在Repeater1.Items的RepeaterItem项) { 文本框txtName的=(文本框)item.FindControl(TextBox1中); 如果(txtName的!= NULL) { 字符串VAL = txtName.Text; //做一些VAL } }}解决方案
您是否尝试过类似下面的按钮点击: -
的foreach(在Repeater1.Items的RepeaterItem项){ 文本框txtName的=(文本框)item.FindControl(改为txtName); 如果(txtName的!= NULL) { //做一些txtName.Text } 图片IMG =(图)item.FindControl(图); 如果(IMG!= NULL) { //做一些IMG }}/ *如果txtName的和IMG是文本框的ID和图像中的中继器分别控制。* /
希望这有助于。
All the ways I can think to do this seem very hackish. What is the right way to do this, or at least most common?
I am retrieving a set of images from a LINQ-to-SQL query and databinding it and some other data to a repeater. I need to add a textbox to each item in the repeater that will let the user change the title of each image, very similar to Flickr.
How do I access the textboxes in the repeater control and know which image that textbox belongs to?
Here is what the repeater control would look like, with a submit button which would update all the image rows in Linq-to-SQL:
Edit:
This code works
Just make sure you don't blow your values away by Binding outside of if(!Page.IsPostBack) like me.. Oops.
<asp:Repeater ID="Repeater1" runat="server"> <ItemTemplate> <div class="itemBox"> <div class="imgclass"> <a title='<%# Eval("Name") %>' href='<%# Eval("Path") %>' rel="gallery"> <img alt='<%# Eval("Name") %>' src='<%# Eval("Path") %>' width="260" /> </a> </div> <asp:TextBox ID="TextBox1" Width="230px" runat="server"></asp:TextBox> </div> </ItemTemplate> </asp:Repeater>And Submit Click:
protected void Button1_Click(object sender, EventArgs e) { foreach (RepeaterItem item in Repeater1.Items) { TextBox txtName = (TextBox)item.FindControl("TextBox1"); if (txtName != null) { string val = txtName.Text; //do something with val } } }解决方案
Have you tried something like following on the button click:-
foreach (RepeaterItem item in Repeater1.Items) { TextBox txtName= (TextBox)item.FindControl("txtName"); if(txtName!=null) { //do something with txtName.Text } Image img= (Image)item.FindControl("Img"); if(img!=null) { //do something with img } }/* Where txtName and Img are the Ids of the textbox and the image controls respectively in the repeater.*/
Hope this helps.
