Problem clearing values in table

[cyfirst]

Hi,
I'm having a problem clearing the values within a table and hoped for some input.  I have a table with values that can be entered by the user.  I also have a clear button, that when clicked executes javascript to set the value to "".  I've added a RadAjaxManager proxy to update the table when the clear button is clicked.  My problem is that the whole table disappears not just the values.  Can you tell me what I am doing wrong? 

<   asp:Table ID="IndexTable" runat="server" EnableViewState="false" >     </asp:Table>     <   asp:Button ID="btnClear" runat="server" Text="Clear" Width="85px"         style="text-align:center;vertical-align:middle;margin-left:10px"        OnClientClick="ClearIndexData();" />     <   telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">   <script type="text/javascript" >   function ClearIndexData() {

//repository

repo = document.getElementById("ctl00_MainContent_hfRepoHint").innerText;

//custom indexes

for (i = 1; i <= 20; i++) {

if (document.getElementById("ctl00_MainContent_radIndex" + i.toString() + "S") != null) {

if (repo.charAt(0) == '5')

document.getElementById("ctl00_MainContent_radIndex" + i.toString() + "S").value = "";

else

document.getElementById("ctl00_MainContent_radIndex" + i.toString() + "S").value = "";

}

else if (document.getElementById("ctl00_MainContent_radIndex" + i.toString() + "R") != null) {

if (repo.charAt(0) == '5')

document.getElementById("ctl00_MainContent_radIndex" + i.toString() + "R").value = "";

else

document.getElementById("ctl00_MainContent_radIndex" + i.toString() + "R").value = "";

}

}

}    </script> </telerik:RadScriptBlock>

And here is the RadAjaxManager proxy settings

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="btnClear">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="IndexTable" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

Thanks in advance for any advice you can give me.

Hello Cyfirst,

Please modify your Button as shown below:

<asp:Button ID="btnClear" runat="server" Text="Clear" Width="85px" Style="text-align: center; vertical-align: middle; margin-left: 10px" OnClientClick="ClearIndexData(); return false;" />

I hope this helps.

Kind regards,

Hi Daniel,
I tried that but it does not update the table then and the values are not cleared out.  I can do it via server code and rebuild the table but since I am only clearing the values, I thought it would be more efficient to just set value to "" via client script.  Any idea why the value would not be updated? 
Thanks,

Hello Chris,

If I understand your scenario properly, the Table is created dynamically in code-behind. Please note that, in such cases, you should recreate the Table on each postback.

Let me know if I'm missing something.
