在checkboxlist上调用gridview按钮单击事件选择索引已更改事件 [英] Calling a gridview button click event on checkboxlist selected index changed event

问题描述

我有一个复选框列表和一个gridview。

Gridview：=

 < ;   asp：GridView     ID   =  grdColumns    runat   =  server    AutoGenerateColumns   =  False    宽度  =  800px  
   
                                                  < span class =code-attribute>                                                       ShowFooter   =  true    CssClass   =  gridtable1 >  
 <  列 >  

 <   asp：TemplateField     HeaderText   = 删除 >  
 <   ItemTemplate  >  
 <   asp：按钮    runat   =  server    ID   =  btnRemove   文字  =  删除    OnClick  < span class =code-keyword> =  btnRemove_Click    /  >  
 <   / ItemTemplate  >  
 <   / asp：TemplateField  >  
 <   /列 >  
 < ;   / asp：GridView  >  

如果我选中/取消选中复选框list.i中的任何项目，我需要在gridview中添加和删除动态行。在btnremove_click中写入代码以删除动态行。

当我点击删除按钮它工作正常。



现在我想调用此按钮点击事件对所选索引更改为checkboxlist，以便这样做我可以删除我想从gridview中的多行删除的特定行。但是它给出了错误。如何实现这个任务？有没有其他方法可以这样做？



帮我...

< pre lang =cs> protected void btnRemove_Click（ object sender，EventArgs e）
{
GridViewRow gvRow =（GridViewRow）（sender as Control）.Parent.Parent;
int rindex = gvRow.RowIndex;

//剩余代码到此处

}

解决方案

只需直接从数据库添加和删除并重新绑定gridview。

或

您可以使用事件处理程序调用

上的按钮单击事件

 protected void Page_Load（object sender，EventArgs e）
 {
 CheckboxID.Change + = new EventHandler（this.btnRemove_Click）; 
} 

i have a checkbox list and a gridview.
Gridview:=

<asp:GridView ID="grdColumns" runat="server" AutoGenerateColumns="False" Width="800px"

                                                   ShowFooter="true" CssClass="gridtable1">
                                                   <Columns>

<asp:TemplateField HeaderText="Remove">
                                                           <ItemTemplate>
                                                               <asp:Button runat="server" ID="btnRemove" Text="Remove" OnClick="btnRemove_Click" />
                                                           </ItemTemplate>
                                                       </asp:TemplateField>
                                                   </Columns>
                                               </asp:GridView>

I need to add and remove a dynamic row from gridview on if i checked/unchecked any item of checkbox list.i have code written inside btnremove_click to remove dynamic row.
When i click on remove button it works fine.

now i want to call this button click event on selected index changed of checkboxlist so that a so that i could delete a paricular row which i want to delete from multiple rows in gridview. But it gives error.How to achieve this task?Is there any other way to do so?

Help Me...

protected void btnRemove_Click(object sender, EventArgs e)
      {
          GridViewRow gvRow = (GridViewRow)(sender as Control).Parent.Parent;
          int rindex = gvRow.RowIndex;

//remaining code goes here
}

解决方案

Simply you can add and remove directly from database and rebind the gridview.
Or
You can use the event handler to call the button click event on the

 protected void Page_Load(object sender, EventArgs e)
    { 
 CheckboxID.Change += new EventHandler(this.btnRemove_Click );
}
