[英]devexpress ASPxGridView column problem
I have an ASPXGRIDVIEW which is binded to an SQL query. 我有一个绑定到SQL查询的ASPXGRIDVIEW。 I added to the grid an additional COLUMNCUSTOMBUTTON.
我在网格中添加了其他的COLUMNCUSTOMBUTTON。 But what happens is, that for all the rows it put a link there.
但是发生的是,对于所有行,它都在其中放置了一个链接。 I am trying to find a way to add to this column a link (button) ONLY to specific rows!
我正在尝试找到一种仅向特定行添加链接(按钮)的方法!
I am unable to understand how to do it 我不知道该怎么做
thanks 谢谢
To add a custom button, add this to your command column in the aspx side: 要添加自定义按钮,请将其添加到aspx一侧的命令列中:
<dxwgv:ASPxGridView ID="grid" ClientInstanceName="grid" runat="server" DataSourceID="AccessDataSource1" KeyFieldName="EmployeeID" AutoGenerateColumns="False" Width="100%" OnCustomButtonCallback="grid_CustomButtonCallback" OnInitNewRow="grid_InitNewRow">
<Columns>
<dxwgv:GridViewCommandColumn VisibleIndex="0">
<EditButton Visible="True" />
<NewButton Visible="True" />
<CustomButtons>
<dxwgv:GridViewCommandColumnCustomButton Text="Create a Copy" ID="Copy" />
</CustomButtons>
</dxwgv:GridViewCommandColumn>
Then in your codebehind: 然后在您的代码背后:
public partial class GridEditing_EditForm : BasePage {
protected void Page_Load(object sender, EventArgs e) {
}
Hashtable copiedValues = null;
string[] copiedFields = new string[] { "FirstName", "Title", "Notes", "LastName", "BirthDate", "HireDate" };
protected void grid_CustomButtonCallback(object sender, ASPxGridViewCustomButtonCallbackEventArgs e) {
if(e.ButtonID != "Copy") return;
copiedValues = new Hashtable();
foreach(string fieldName in copiedFields) {
copiedValues[fieldName] = grid.GetRowValues(e.VisibleIndex, fieldName);
}
grid.AddNewRow();
}
protected void grid_InitNewRow(object sender, DevExpress.Web.Data.ASPxDataInitNewRowEventArgs e) {
if(copiedValues == null) return;
foreach(string fieldName in copiedFields) {
e.NewValues[fieldName] = copiedValues[fieldName];
}
}
}
