From codebehind use

search.Attributes.Add("onblur", "javascript:CheckMyConditions(this);");

where
CheckMyConditions is your javascript function which checks the values. Rose | [Rose]

You may want to consider using JQuery[^]. It provides a nice easy to use framework for what you are doing and more.

Hey, I think this might help you.

This seems to be a bug in Visual Studio 2008 for 64Bit machines. Lets try out the workarounds.. If you can fix it.

greendragons wrote:

Yes of course. Just define a function in your JS file, add that using script tag and call its function.

Say you write like this :

function selectValue(obj)
{
   alert(obj.value);
}

If you write
txtbox.Attributes.Add("onblur", "javascript:selectValue(this);");
It will eventually produce an alert message with the value you provided in the textbox.

Other than that, if you want to call like this :
window.onload=initAll;

The function declaration of initAll should be before the actual call. Otherwise undefined handler will be assigned to the event. Smile | :)

Hope this helped you. Thumbs Up | :thumbsup:

How to persist 'doubled up' usercontrol in a datalist and a repeater control across a postback - arghhh!

Fu Manchu4-Nov-09 3:21

Hi guys,

I don't know which way to go with this i think ive exhausted all efforts. My usercontrol display information but when i click update a full page postback occurs and i lose everything, my control disappears!

I have an extremely large amount of data to display to the users, so using exsiting controls like a gridview is just silly. I've opted for a usercontrol that displays a set of prices by location and product. I have also given the user a couple of checkbox controls to be able to select groups of locations and groups of products.

Ive put my usercontrol in another with a datalist and a objectdatasource that gets a list of the locations and this accepts a productID, this is why im saying 'doubled up'. A usercontrol within a usercontrol! Not sure if this is the best solution? Because i cant directly access the control with a datalist?

On the main form, i have a repeater control with the usercontrol inside it. This repeats the locations selected (9 max) (created by the datalist) for every product (33 max) selected if you get me! Each control has an update button, but when its clicked the controls disappear.

Listed below is the second control:-

<asp:DataList ID="DataList1" runat="server" RepeatColumns="3" <br />
    DataSourceID="ObjectDataSource1"><br />
<br />
         <ItemTemplate><br />
<br />
	<br />
	   <uc1:CompanyPriceWidget ID="CompanyPriceWidget" runat="server" companyName='<%#Eval("Company.CompanyName")%>' <br />
	   productCost='<%#Eval("StockItemProductCostSterling")%>' retailSalePrice='<%#Eval("StockItemRetailSalePriceSterling")%>'<br />
	   productCostOverHead= '<%#Eval("StockItemProductCostOverHead")%>' retailSalePriceOverHead='<%#Eval("StockItemRetailSalePriceOverHead")%>'<br />
	   ExchangeRate='<%#Eval("Company.CurrencyExchangeRate.CurrencyRate")%>' companyId='<%#Eval("Company.CompanyID")%>' OnUpdateValues="CompanyPriceWidget_UpdateValues" /><br />
            <br />
	   <br />
	    </ItemTemplate><br />
<br />
        </asp:DataList>   <br />
     <br />
        <br />
<br />
  <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" <br />
               SelectMethod="GetListOfStockValueGroupedByCompany" <br />
               TypeName="StockValueSterlingDel" <br />
    OldValuesParameterFormatString="original_{0}"><br />
               <SelectParameters><br />
                   <asp:Parameter Name="stockItemPriceBandId" Type="Int32" /><br />
               </SelectParameters><br />
           </asp:ObjectDataSource><br />
<br />

On the Main Form

<br />
           <asp:Repeater ID="Repeater1" runat="server"><br />
<br />
        <ItemTemplate><br /><br />
<br />
        <h1><%#Eval("Description")%></h1><br />
<br />
            <uc2:StockValueWidget ID="StockValueWidget1" runat="server" StockItemPriceBandId='<%#Eval("StockItemPriceBandID")%>' /><br />
<br />
        </ItemTemplate><br />
<br />
        </asp:Repeater>

The form runs fine, but when i click to update the values i.e a postbasck occurs my control disappears.
Does anyone know a way of doing this dynamically? Or knows how the repeater control works with usercontrols!

Thanks
Andy

So as I can make out ....
There are 2 Different User Controls one in dataList and other in Repeater control
....... and the problem which you are facing is that on postback the UserControl inside the repeater disappears

In this case check whether on Page load(After Postback) the conrols are rendered .........

Thanks for your reply,

I have a render event in my control that fires to fill up the textboxes etc... You have given my an idea to why this is happening, it appears that the value thats in passed to the first control is now 0 at postback, i'll have to create some kind of collection to store these in session. However when i fix this value, the controls a rendered but i now lose all my data as everything goes to 0. So is appears that all the data in the controls is lost due to the postback.

this is going to be one almighty collection stored in session, the viewstate is going to be massive!

Thanks for your help
Andy

You can use drag & drop to place the image in your solution or the context menu, Add Existing Item. However, if you haven't been able to figure this out, then the tool is beyond your current capabilities and skills. Find another tool, learn the current one, or quit while you're behind.

Erhm, I don't clearly understand your question, however what I made up, is that you're developing an ASP.NET website using C#, and you want the display I file which you can select from harddrive. Im I correct here? Have you considered reading Konstantin Vasserman's article
File Upload with ASP.NET[^] which helps you step by step?

Something like this?

function LoadDataRow()
{
    var img = document.GetElementById("image");
    img.style = "visible";

    // Load data

    img.style = "hidden";
}

Are you serious? If you can't figure that out you should not attempt this project. Go to your manager and tell them you are not capable of theis work and ask to be reassigned to the mailroom.

Thanks for reply. Currently the biggest problem is documentation, I've started writing manual already and going to write article for codeproject. I hope it will be published in about two weeks.
