[英]Webforms: How to disable a button that is inside a Telerik RadGrid in code behind
I am new working with webforms. 我是使用Webforms的新手。 I learned MVC first.
我首先学习了MVC。 I have a Telerik RadGrid that has a MasterTableView inside and then, a couple of columns inside this MasterTableView.
我有一个Telerik RadGrid,里面有一个MasterTableView,然后在这个MasterTableView中有几列。 I want to simply disable some buttons in the code behind but Visual Studio keeps telling me that the buttons does not exists.
我只想在后面的代码中禁用某些按钮,但是Visual Studio不断告诉我这些按钮不存在。 In a Google search I found that the reason is because the buttons are inside the RadGrid.
在Google搜索中,我发现原因是因为按钮位于RadGrid内部。 However I didn't find any example to access them.
但是我没有找到任何访问它们的示例。
The buttons are inside the radgrid and they looks like this: 这些按钮位于radgrid内部,它们看起来像这样:
<telerik:GridTemplateColumn HeaderStyle-Width="72px" HeaderText="Acciones" >
<ItemTemplate >
<div style="width: 100px">
<span style="position:relative;" class="grid-buttonColor1">
<i class="material-icons">create</i>
<asp:Button ID="btnEditReportDetail"
CommandArgument='<%# Item.ReportDetailId %>'
OnClick="btnReportDetail_Click"
runat="server"
Style="position:absolute; opacity:0; top:0; left:0; width:100%; height:100%;"
type="button"
causesvalidation="false" />
</span>
<span style="position: relative;" class="grid-buttonColor2">
<button
type="button"
style="background-color: transparent; border: none; padding: 0"
data-toggle="modal"
data-target="#MessageBoxModal"
onclick="ShowMessageBoxWithMessage_<%= ucMessagebox.ClientID%>('Confirmación', '¿Está seguro que desea eliminar la tarea?','DeleteTaskReports','<%# Item.ReportDetailId.ToString() %>')">
<i class="material-icons prefix">delete</i>
</button>
</span>
</div>
</ItemTemplate>
</telerik:GridTemplateColumn>
How can I access those buttons in order to write in the code behind something like: buttonName.Enabled = false;
我该如何访问这些按钮,以便在类似以下代码的地方编写代码:
buttonName.Enabled = false;
Please! 请! This is driving me crazy!
这真让我抓狂!
Thank you guys! 感谢大伙们!
May be this will help you 也许这会帮助你
protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
if (e.Item is GridDataItem)
{
GridDataItem item = (GridDataItem)e.Item;
Button btn = item.FindControl("img1") as Button;
btn.Enabled = false;
}
}
or 要么
protected void RadGrid1_PreRender(object sender, EventArgs e)
{
if ("your Condition")
{
foreach (GridDataItem dataItem in RadGrid1.MasterTableView.Items)
{
((Button)cmdItem.FindControl("btnEditReportDetail")).Visible = false;
}
}
}
You need to use FindControl
to find server control that inside of Grid. 您需要使用
FindControl
在Grid内部查找服务器控件。
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
Button button = e.Row.FindControl("Button1") as Button;
button.Enabled = false;
}
