C# - How To Delete A GridView Row


I have this code until now: <asp:TemplateField ShowHeader="False" ItemStyle-Width="150px" HeaderStyle-BackColor="#003ca1" HeaderStyle-ForeColor="white"> <ItemTemplate> <asp:LinkButton ID="linkDelete" runat="server" CausesValidation="False" CommandName="Delete" OnClientClick='return confirm("Diesen Eintrag wirklich löschen?");' Text="Löschen" /> </ItemTemplate> </asp:TemplateField> At this moment, the GridView deletes the row physically.I want to catch this in CodeBehind, cancel the delete-operation and want only set a "IsDeleted"-Flag in the database.

C# - How To Hide A Column In The Table Based On A Boolean Variable stackoverflow.com

So I have an <asp:Gridview> and in my C# file, I am setting the datasource to some database table, and doing .DataBind(). However, I want to hide a column in the table based on a Boolean variable. Something like this: gridview.Columns['Field5'].Visible = false; Or perhaps: int c = gridview.Rows.Count(); for(int i = 0; i < c; i++){ gridview.Rows['Field5'].Remove(); } Perhaps I cannot make it invisible, but I'm sure I can at least loop through and remove all rows related to the column "field5". I don't know how to go about doing this. Does anyone perhaps have a proper link to using the GridView Class and how all the methods are suppose to be used because it's not clear, perhaps not written by microsoft? the internet seems to lack a lot of C# documentation (or maybe it's just cluttered with too much useless ASP.net information).

Bind Button Visibility To The Expression (C#)? stackoverflow.com

I have a delete button in each row of GridView (component ASP.NET). I want some of the delete buttons to be invisible. The visibility of the delete button should depend on the data that are back the row. GridView is backed by EntityDataSource. GridView displays entities called Category, one instance in each row. Entity Category has (besides others) also a field of type EntityCollection. Name of that field is Items. Basically I want to allow user to delete a row only if the Items field of backing Category entity is an empty collection. This is how the button looks right now: <asp:Button ID="DeleteButton" runat="server" CommandName="Delete" Text="Delete" Visible=??? ></asp:Button> I don't know what should replace ???. The button schold be visible only when this expression evaluates to true: ((SimpleEShop.Model.Category) dataItem).Items.LongCount() <= 0 where dataItem variable contains data of current row in the table. What is the binding that I need ?

Forms Data Controls :: Explicitly Call ButtonAdd_Click1 (object Sender - EventArgse) forums.asp.net

In my GridView control I have a template field with a button labeled "Add New Row" When that button is pressed a method in the C# code named ButtonAdd_Click1 is being called. It works great, but there are times when I need to explicitly call ButtonAdd_Click1(object sender, EventArgs e) even when the "Add New Row" button is not being pressed. How can I do that? You see I also have a check box on my web form (Not in the GridView) and when it is checked, my ButtonAdd_Click1(object sender, EventArgs e) method will also need to be called. I think the bigger question here might be, what parameters do I pass for "sender" and "e" in the parameter list when my check box is checked? Aspx code in my Grid:<asp:TemplateField HeaderText="News Summary <br/> NewsFeed" > <ItemTemplate><asp:TextBox ID="TextBox10" runat="server" Width="91px"></asp:TextBox></ItemTemplate><FooterTemplate> <asp:Button ID="ButtonAdd" runat="server" Text="Add New Row" onclick="ButtonAdd_Click1" Width="99px" /></FooterTemplate><FooterStyle HorizontalAlign="Right" /> </asp:TemplateField> <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" /> C# method in my C# code behind: protected void ButtonAdd_Click1(object sender, EventArgs e) { Proceess(); }

Nested GridView Row Event Pandemonium stackoverflow.com

I have come across odd behavior involving nested gridview controls and row events. Basically the nested gridview row event will not fire unless it is in the last row of the outer grid. If you explicitly add the row event property to the markup (e.g. OnRowDeleted="gvInner_RowDeleted") then the row event fires for all nested gridviews however it fires twice for the nested gridview in the last row of the outer gridview EDIT: I should note that I am using the SqlDataSource for the outer gridview as it is also editable. This isn't clear in the example. Markup: <asp:GridView ID="gvOuter" DataSourceID="sdsOuter" runat="server" OnRowDatabound="DynamicControlAdder" AutoGenerateColumns="false"> <Columns> <asp:BoundField DataField="Id" ReadOnly="true" /> <asp:TemplateField> <ItemTemplate> <asp:UpdatePanel ID="upInner" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:GridView ID="gvInner" DataSourceId="sdsInner" runat="server" DataKeyNames="Id" AutoGenerateColumns="false"> <Columns> <asp:CommandField ShowDeleteButton="true" /> <asp:BoundField DataField="Id" /> </Columns> </asp:GridView> <asp:SqlDataSource ID="sdsInner" runat="server" ProviderName="<%$ ConnectionStrings:YourString.ProviderName %>" ConnectionString="<%$ ConnectionStrings:YourString %>" SelectCommand="SELECT * FROM tblInner WHERE OuterTableKey = @OuterTableKey" DeleteCommand="DELETE FROM tblInner WHERE Id = @Id"> <SelectParameters> <asp:Parameter Name="OuterTableKey" DefaultValue="0" Type="Int32" /> </SelectParameters> <DeleteParameters> <asp:Parameter Name="Id" DefaultValue="0" Type="Int32" /> </DeleteParameters> </asp:SqlDataSource> </ContentTemplate> </asp:UpdatePanel> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> <asp:SqlDataSource ID="sdsOuter" runat="server" ProviderName="<%$ ConnectionStrings:YourString.ProviderName %>" ConnectionString="<%$ ConnectionStrings:YourString %>" SelectCommand="SELECT * FROM tblOuter"> </asp:SqlDataSource> Code: Partial Class Testing Inherits System.Web.UI.UserControl Protected Sub DynamicControlAdder(ByVal sender As Object, ByVal e As GridViewRowEventArgs) If e.Row.RowType <> DataControlRowType.DataRow Then Exit Sub End If Dim s As SqlDataSource = CType(e.Row.FindControl("sdsInner"), SqlDataSource) s.SelectParameters("OuterTableKey").DefaultValue = e.Row.DataItem("Id").ToString() End Sub Protected Sub gvInner_RowDeleted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewDeletedEventArgs) Handles gvInner.RowDeleted //'This never fires unless it is the last row in the outer gridview //'also, if this event is declared in the OnRowDeleted property of the inner gridview, this event fires twice if it is in the last row of the outer grid Dim strFoo As String = "Foo" End Sub End Class
