How do I delete an item from a asp:Repeater? At the moment I have the following code for the repeater:
<asp:Repeater ID="uxRolesList" runat="server">
<ItemTemplate>
<div id="<%# GetRolesDivId() %>">
<asp:TextBox ID="uxTxtBoxRole" runat="server" rows="5" columns="100" Text='<%# Container.DataItem %>' TextMode="multiline" MaxLength="2000"></asp:TextBox>
<asp:Button ID="uxRemoveRoleBtn" Style="vertical-align:top;" CssClass="remove-roles-btn" runat="server" Text="X" />
<br />
<asp:RequiredFieldValidator runat="server" ID="uxValTxtBoxRole" ControlToValidate="uxTxtBoxRole" ErrorMessage="Please complete this role requirement"></asp:RequiredFieldValidator>
<br /><br />
</div>
</ItemTemplate>
</asp:Repeater>
Which should output something like this:
<div id="roles-1">
<textarea name="ctl00$mainContent$uxRolesList$ctl01$uxTxtBoxRole" rows="5" cols="100" id="ctl00_mainContent_uxRolesList_ctl01_uxTxtBoxRole">Quick test</textarea> <input type="submit" name="ctl00$mainContent$uxRolesList$ctl01$uxRemoveRoleBtn" value="X" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$mainContent$uxRolesList$ctl01$uxRemoveRoleBtn", "", true, "", "", false, false))" id="ctl00_mainContent_uxRolesList_ctl01_uxRemoveRoleBtn" class="remove-roles-btn" style="vertical-align:top;" />
<br />
<span id="ctl00_mainContent_uxRolesList_ctl01_uxValTxtBoxRole" class="error" style="color:#891F11;display:none;">Please complete this role requirement</span>
<br /><br />
</div>
And I'm using the following jQuery to 'delete' the item when the delete button is clicked:
$("#roles-" + roleIdNumber).remove();
e.preventDefault();
rolesCounter--;
Where roleIdNumber is 1 in this case.
But when I submit the form, the item still appears - can anyone help me with what is happening?
i suggest replacing:
<div id="<%# GetRolesDivId() %>">
with:
<div id="<%# GetRolesDivId() %>" class="div_row">
and this line:
<asp:Button ID="uxRemoveRoleBtn" Style="vertical-align:top;" CssClass="remove-roles-btn" runat="server" Text="X" />
with:
<input type="button" style="vertical-align:top;" value="X" class="remove-roles-btn" onclick="$(this).parents('.div_row').remove();rolesCounter--;" />
and remove all the js code you shared here.
hope it helped.
