Client-Side Delete from Gridview(Hide-row and delete when page is saved)
Is there any way to hide a row dynamically in a gridview without a postback? Each row in my grid has a delete button. When the delete button is pressed I want it to appear to the user as if the corresponding row has been deleted. The delete won't actually take place until there is a postback.
I am using asp.net and javascript. Here is a stripped down version of what I have.
<script type="text/javascript" > function getParentObjectId(fromId) { var str; var indx; indx = fromId.lastIndexOf("_"); str = fromId.substring(0, indx); return str; } function delcpt(rowitem) { var rowid = getParentObjectId(rowitem.id); document.getElementById(rowid).style.display = 'none'; } </script> <asp:GridView ID="gvCPT" runat="server" DataKeyNames="Value" AutoGenerateColumns="False" Width="570px"> <Columns> <asp:TemplateField> <ItemTemplate> <INPUT id="btnDelCPT" onclick="delcpt(this);" type="button" /> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView>
I am getting a javascript error because 'rowid' is null.

Hello,
You can easily accomplish this using AJAX.NET and no javascript at all.
Below is an example which is self explanatory:
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ID" DataSourceID="SqlDataSource1" EmptyDataText="There are no data records to display."> <Columns> <asp:BoundField DataField="ID" HeaderText="ID" ReadOnly="True" SortExpression="ID" /> <asp:BoundField DataField="VenueName" HeaderText="VenueName" SortExpression="VenueName" /> <asp:BoundField DataField="City" HeaderText="City" SortExpression="City" /> <asp:TemplateField> <ItemTemplate> <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> </ContentTemplate> </asp:UpdatePanel>
Code Behind:
protected void Button1_Click(object sender, EventArgs e) { Button btn = (Button) sender; GridViewRow row = (GridViewRow)btn.NamingContainer; GridView1.Rows[row.RowIndex].Visible = false; }
This will hide the row in which the button is clicked. To retrieve all of the rows you hide, you can add them to an array or collection in the button1_click event and retrieve it later. Or just loop though the gridview and find the rows you set the visibility to false. Like the following:
foreach(GridViewRow row in GridView1.Rows) { if(row.Visible == false) Response.Write(row.Cells[1].Text); }
Hope this helps.

Thanks for you answer. I have actually found an even better way using javascript that won't even require an Ajax roundtrip to the server.
Here it is:
<script type="text/javascript" > function getObjectInUC(fromId, targetId) { var str; var indx; indx = fromId.lastIndexOf("_"); str = fromId.substring(0, indx); str = str + "_" + targetId; return $(str); }//getObjectInUC function delrow(rowitem) { var row = rowitem.parentNode.parentNode; row.style.visibility = "hidden"; row.style.display = "none"; var target = getObjectInUC(rowitem.id, 'hdnVisible'); target.value = 0; } </script><asp:TemplateField ItemStyle-Width="30px"> <ItemTemplate> <input id="btnDelCPT" runat="server" onclick="delrow(this);" type="button" /> <input type="hidden" id="hdnVisible" runat="server" value="1" /> </ItemTemplate> </asp:TemplateField>//In the code behind when the save button is pressed I simply find out which rows contain hdnVisible.value = 0 and delete them.foreach (GridViewRow row in gvCPT.Rows) { HtmlInputHidden hdnVisible = row.FindControl("hdnVisible") as HtmlInputHidden; if (hdnVisible.Value == "0") {//code to delete } if (hdnVisible.Value == "1") {//code to save } }

deleting a gridview row > deleting a record by id?
I know this is supposed to be really simple but I'm stumped, despite all my reading: I've got a gridview full of 'Categories' pulled rom my SQL db; each row has a (hidden) 'category_id' column. My delete button should ensure that the appropriate record is marked for deletion by category_id. I understand that somehow the point of a datagrid is that it is bound to my datatable - but how do I leverage that so that deleting a grid row (which might be row index 1) finds and deletes the correct record (which might be category_id 3125)?
