Find controls embedded in repeater management system

I am trying to find the TextBoxes values ​​that are displayed in the Repeater, although the UserControl, i.e. Repeater has a Placeholder for the UserControl, and inside the UserControl there is a TextBox markup. Earlier, I did this with TextBoxes directly inside the repeater, which was pretty straight forward, and I wonder why this, apparently, cannot be achieved the same way. Here is the default repeater page containing Placeholder ...

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <form class="formee"> <fieldset> <legend>Faculty Information</legend> <div class="grid-4-12"> <asp:Label ID="lblFirstName1" runat="server" Text="First Name"></asp:Label> <asp:Label ID="lblFirstName2" runat="server" Text="" ></asp:Label> <asp:Label ID ="lblSalary" runat="server" Text="" ClientIDMode="Static"></asp:Label> </div> <div class="grid-6-12"> <asp:Label ID="lblLastName1" runat="server" Text="Last Name"></asp:Label> <asp:Label ID="lblLastName2" runat="server" Text=""></asp:Label> </div> </fieldset> </form> <div id="repeaterDiv"> <asp:Repeater ID="rptBudget" runat="server" ClientIDMode="Static"> <ItemTemplate> <asp:PlaceHolder ID="phBudget" runat="server" EnableViewState="true" /> <br /> </ItemTemplate> </asp:Repeater> <asp:Button ID="btnAddBudgetControl" runat="server" Text="Add" CausesValidation="false" OnClick="AddBudgetControl" CssClass="addBudgetControl"/> <asp:Button ID="btnDisplayEntries" runat="server" Text="Display Entries" CausesValidation="false" OnClick="DisplayEntries" /> </div> <div> <asp:TextBox ID="txtTotalPercent" runat="server" ClientIDMode="Static"></asp:TextBox> <asp:TextBox ID="txtGrandTotal" runat="server" ClientIDMode="Static"></asp:TextBox> <asp:Label ID="lblCtrls" runat="server" Text=""></asp:Label> </div>

... and UserControl, which is inserted instead of Placeholder ...

  <fieldset> <legend>Faculty Salary Form</legend> <table cellspacing="10" id="values"> <tr> <td> <asp:Label ID="lblServiceType" runat="server" Text="Service"></asp:Label> <asp:DropDownList runat="server" ID="ddlServiceType" CssClass="serviceType" /> </td> <td> <asp:Label ID="lblSpeedCode" runat="server" Text="Speed Code"></asp:Label> <asp:DropDownList runat="server" ID="ddlSpeedCode" CssClass="speedType" /> </td> <td> <asp:Label ID="lblPercentage" runat="server" Text="Percentage"></asp:Label> <asp:Textbox ID="txtPercentage" runat="server" CssClass="percentCommitment" ClientIDMode="Static" EnableViewState="true" /> </td> <td> <asp:Label ID="lblTotal" runat="server" Text="Total"></asp:Label> <asp:TextBox ID="txtTotal" runat="server" CssClass="amountCommitment" ClientIDMode="Static" EnableViewState="true"/> </td> <td> <asp:Button ID="btnRemove" runat="server" Text="Remove Item" OnClick="RemoveItem" ClientIDMode="Static" CssClass="btnRemove" /> </td> </tr> <tr> </tr> </table> </fieldset>

... but when the following code runs for the Display OnClick button, I always get a null value for all and all text fields (and DropDowns) in UserControl ...

 protected void DisplayEntries(object sender, EventArgs e) { foreach (RepeaterItem repeated in rptBudget.Items) { TextBox txtPercentage = (TextBox)repeated.FindControl("txtPercentage"); if (txtPercentage == null) { lblCtrls.Text += " null; "; } else { lblCtrls.Text += txtPercentage.Text + "; "; } } }

What is the best way to access these values? Thanks.

The txtPercentage text field is inside the Usercontrol, so use the following helper method to get it.

Helper method

 public static Control FindControlRecursive(Control root, string id) { if (root.ID == id) return root; return root.Controls.Cast<Control>() .Select(c => FindControlRecursive(c, id)) .FirstOrDefault(c => c != null); }

Using

 foreach (RepeaterItem repeated in rptBudget.Items) { TextBox txtPercentage = (TextBox)FindControlRecursive(repeated, "txtPercentage"); ... }

You need to get UserControl first and then use FindControl in UC itself.

First try loading the placeholder, and then find the text fields in the placeholder:

Something like that:

pseudo

 var ph = repeated.FindControl("phBudget"); var txtBox = ph.FindControl("txtPercentage");

/pseudo
