ASP.NET 2005 / both Javascript and Anthem (ajax ctrls) stopped working.

Hi great minds,

A asp.net app that make use of Anthem ajax-enabled controls, and some javascript as well, has suddenly stopped working. Ajax controls no longer issue their requests and on top of this, javascripts no longer work.

Javascript stopped working first and a day or two later the anthem controls. We get no compliler errors or whatsoever. I thought the IDE got broken because a previous OPERATIONAL version works on another computer, but not in one I am using. I have re-installed VS2005 but it still does not work.

Would this be due to one of those windows updates? any sugestions?

thank you so much for your time and help.

See,
You can use TextBox in Gridview using Template Field.

Grid View having inbuilt features of Edit. You need to enable the Edit Mode of Gridview and Handel the RowEditing events.

how to implement MVVM design pattern in asp.net

Dear All,

I have a case that I will need to retrive a webusercontrol XHTML from database and inject it in a web page at runtime the issue is that I don't find an Xhtmlreader class in c#, I understand that XHTML code in asp.net will need to be transformed to html before it can be rendered to a web browser and that might be the reason for not having such class in c#. another question is that is there a way to implement MVVM design pattern in asp.net. I've searched for that in google and found a demo or what they called ASP.Net MVVM Framework in codeplexi but it looks more like they use MVP Pattern becuase there is a behind code for the Webusercontrols they use, in other words I need to have the whole functionality and binding features of an asp.net webusercontrol with a gridview or formview without need to write behind code.

Many Thanks and best regards
Hassan Ali

Read listing three in that page. It shows how to restrict the user to uload only a certian file types. Ofcourse the regular expression that they have used needs a change in your case. But it it mere customization and should not be a problem.

How to open a url in a new browser window in Ajax page

Hi,

I am working on a Asp.net project. Here we need to display a URL in a new browser window with custom size like a popup. For this I tried with below code:

Page.RegisterStartupScript("New Window", "<script language=JavaScript>window.open('Default.aspx','mywindow','width=500,height=300');</script>");

This is working in all the my project pages. But this is not working in one of my project page where I used Ajax extenders like calender extender, Auto complete extender etc. So I also tried with

ClientScript.RegisterClientScript()

but eventhen it is not working.

If anyone have any idea to solve this please reply me.

Thanks in advance.

Can you please tell us what error you are getting?

If no error, then have you checked what it appears in View-Source in Browser?

Also check if popup is blocked in your browser for that site.

Instead of
ClientScript.RegisterClientScript() use ScriptManager.RegisterStartupScript() when the call is inside UpdatePanel.

First of all,

You might have used ItemDataBound to set the value of TextBox. Also to remind, if you are using a Repeater, and the imagebutton is inside the ItemTemplate, you are having more than one ImageButton while there will be only on textbox which is placed outside the textbox.

If you want the text to appear whenever you click on the ImageButton, there is also a problem. You said, you have placed the Repeater inside an undatepanel while the textbox is outside it. In case of UpdatePanel, a separate form is created in the client and posted to the server as request with only those controls which are inside the UpdatePanel. Thus in server side, if you set the value of the Textbox, it will not be transferred to the client and therefore will not update the control in the client.

So Rather than updating the server side object, you can either place the textbox inside the update panel or you inject some javascript which will update the value of the textbox upon receiving the response to the client.

I am talking about

ScriptManager1.RegisterStartupScript()

I hope you got the idea.
Cheers.

You can access the grid view's text boxes from javascript by using the controls client id. it will generally be in the patter gridid$controlid$slno. You can get this by viewing the client HTML source on the browser.

I don't have access to VS 2005 or greater at work so here is a sample with VS 2003/ASP.NET 1.x -

For this datagrid

<asp:DataGrid id="DataGrid1" style="Z-INDEX: 102; LEFT: 208px; POSITION: absolute; TOP: 160px"
    runat="server" AutoGenerateColumns="False">
    <Columns>
        <asp:TemplateColumn HeaderText="sd" FooterText="as">
            <ItemTemplate>
                <asp:TextBox ID="abc" Runat="server" Text="asd"></asp:TextBox>
            </ItemTemplate>
        </asp:TemplateColumn>
    </Columns>
</asp:DataGrid>

and this code

DataTable asd = new DataTable("asd");
asd.Columns.Add("asd");
DataRow dr = asd.NewRow();
DataRow dr1 = asd.NewRow();
dr[0]=asd;
dr1[0]=asd;
asd.Rows.Add(dr);
asd.Rows.Add(dr1);
DataGrid1.DataSource= asd;
DataGrid1.DataBind();

the client ids for the 2 text boxes generated would be DataGrid1__ctl2_abc and DataGrid1__ctl3_abc

You can use this id in the getElementById method in javascript to access the data.

NOTE - Client id generated in higher version of ASP.NET will be similar but not exactly the same.

error in showing blogs in the web site

I have made a web form in which I have taken the following components:

two labels: lbHeading and lbDescription

two textBoxes: txtHeading and txtDesc

two buttons: btnAddArticle and btnCancel

one GridView: GridView1

When I'm adding some article, it is saved in the table "tbArticle" and show both the contents(i.e. heading and article description) in the grid view using SQlDataAdapter.

But when I refresh the page, it's adding the article twice in the table and then showing twice... When again I refresh the page, it again adds the entry even without clicking the "add button"...
what could be the error ?

plz try to fix it
One thing I want to tell you is that adding the entry of articles is done in the "add" button click event.

When you press refresh, the browser posts the last action to the server again, in this case, the last action u did was the add button click. Hence the server exec the add button click event which posts another copy to the database. This is default browser behavior.

To prevent this you can do either of the following -

* Place a refresh button and on the click event refresh the datagrid only.

OR

* After the Add click event is completed, register an client script to refresh the url, which would reset the last action. Use the window.location.href to set the url to the same page.

I have set the code-behind method ..So, I can't use window.location.href.or any client scripting of .cs
could u tell me how to use the first method i.e. placing the refresh button and so on...

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
