I have a radiobuttonlist control in an AJAX tabpanel, which I would like not to postback whenever the selected item is changed. But I do want to modify the text in a textbox, that is within a separate updatepanel, to be the text of the new selected item.
View 2 RepliesI have 1dropdownlist and 1 textbox in my page
I want when I select item from DropDownList in textbox write"Correct" so I wrote below code
protected void DDLclass_SIC(object sender, EventArgs e)
{
Txtsub1.Text = "Correct";
}
but it didn't worked when I select Item from DDL in textbox didn't wirte "Correct"
How I can do it?
I retrieve a record on my database through Page_Load event here's the content of my Code:
hMenuID.Value = Request.QueryString["id"];
//Display information of links on the entries
cnDBConnection.ConnectionString = clsFunction.strConnection;
cnDBConnection.Open();
cmModule.Connection = cnDBConnection;
cmModule.CommandText = "SELECT * FROM modules WHERE id=" + clsFunction.ReplaceString(hMenuID.Value.ToString());
rdModule = cmModule.ExecuteReader();
if (rdModule.HasRows == true)
{
rdModule.Read();
txtModuleLabel.Text = rdModule["name"].ToString();
txtModuleLink.Text = rdModule["link"].ToString();
cboParentID.SelectedValue = rdModule["menuid"].ToString();
}
cmModule.Connection.Close();
rdModule.Close();
cnDBConnection.Close();
So, the data appears on my textboxes and a combo box. I tried to modify the content of my textbox and click on the Update button. Unfortunately, there's no modification that happen. Here's my code in the Update button
Code:
if (Page.IsPostBack)
{
if (Page.IsValid)
{
cnDBConnection.ConnectionString = clsFunction.strConnection;
cnDBConnection.Open();
cmModule.Connection = cnDBConnection;
cmModule.CommandText = "UPDATE modules SET name='" + clsFunction.ReplaceString(txtModuleLabel.Text.Trim()) + "', link='" +
clsFunction.ReplaceString(txtModuleLink.Text.Trim()) + "', menuid=" + cboParentID.SelectedValue +
" WHERE id=" + hMenuID.Value;
cmModule.ExecuteNonQuery();
cmModule.Connection.Close();
cnDBConnection.Close();
}
}
I develop an ASP.NET web application. The server side receives a stream of image data (JPEG frames as byte arrays).
It should processes them and send the images to the client side periodically.
For displaying these images on the client side I tried to use an approach similar to this described in the post "Improve your Image(s)" (http://steveorr.net/articles ImproveYourImages.aspx) by using an auxiliary ASP.NET page for the purposes of the server side image processing.
When I used a client side button to request the image ocntrol (imgCameraCapture) update with its URL pointing to the processing page (GenImage.aspx, as in the above post), everything worked fine (with exception of the whole page re-rendering on each button event). The image was updated.
For a periodic update of the client image control on the main page I put in an ASP.NET AJAX UpdatePanel andset it to update conditionally by triggering to an ASP.Net AJAX timer (10 seconds) event in order to achieve a partial page update (just the image).
II used the timer tick event handler to update the image by invoking the separate ASP.NET image data processing page there as in the button click event handler. But in the timer tick event handler the processing page was not invoked and the image was not updated.
This is the C# code behind executed in the button clik and timer tick event handlers:
imgCameraCapture.ImageUrl = "~/GenImage.aspx";
I have a question regarding to the text in the html code. I would like to know if there is a way to change the content text in the html with text that has been written in textbox. For example i have following text in html, so how can I replace this text by using a text box in the server side.
View 2 RepliesI can't get over the problem with my TextBox. It's inside an UpdatePanel. There is button and code behind for the button_click event that should write the TextBox.Text to a text file, but it does not :-(

This is my problem :
I have a gridview inside an updatepanel and i modified some headers in order to filter the collection. This worked but when my updatepanel is updating, my textbox for the filter clear the value (the text) and lost focus.

I have a very simple application that works almost all the time. I am using an UpdatePanel. My script manager is configured to enable partial rendering. My UpdatePanel is configured for conditional update mode. My asynchronous trigger is a timer that runs every 3 seconds. I track unhandled exceptions in the database. I am not getting any unhandled exceptions. Nor am I getting managed exceptions. Now, I had two users side by side running the application today. I had one record in the data queue. The first user did not get updates; her grid did not update. The second user did get updates. The only difference was that the first user was logged in for a long period of time. The second user logged in just before the test. I reviewed the IIS log file and both users were polling the page every 3 seconds for the same data. So why didn't the first user's grid update? The code follows.
<asp:ScriptManager ID="ScriptManager1" runat="server" AsyncPostBackTimeout="30" EnablePartialRendering="true"></asp:ScriptManager>

In my code behind I have the following timer logic. [Code]....
I have a couple of dropdowns inside an Ajax Update Panel. When I try to rebind the controls or set the selected index of the drodowns inside the panel, they don't respond.
For example, I update the database records and need the dropdowns to display updated data. I set the data source for the dropdowns, rebind them and update the UpdatePanel, but it still shows the old data.

this is my first post in this forum, even though I often search for helps and clarifications over its threads. And many times they are definitely useful!!I had a <asp:ScriptManager> in may MasterPage, wich was used to manage various UpdatePanels I have either in Content pages or in MasterPage.Today I inserted a CalendarExtender, so I had to replace the ScriptManeger with the AJAX ToolkitScriptManager.
At the beginning it seemed to work fine (the calendar pop up and others controls got updated properly). Then I noticed that the nodes in various TreeView are not expanding any more. The TreeViews objects are placed inside an UpdatePanel, in order to expand each node without refreshing the whole content page. And, while a node expands, an UpdatePanel containing a GridView in the content page gets updated.Now, with the new ScriptManager they do not expand, but when clicking on a single node the GridView is updated properly.Here some pieces of code:

Controls registered as triggers.I know I can use only one script manager per page,
I am creating a web part, which is loading an ASCX file. This ASCX contains an Updatepanel and linkbutton inside the update panel.
When i click on the link button for the first time, there is a request going to the server, but the UI is not getting updated. and if you click on it for teh second time, there is not even the request going to the server.
I tried using a button also, but there was no luck, the results were same, first time request fires, but the UI is not updated. and the second time even the request is not fired.
I have put the code for both below. i am using Sharepoint 2007 and My master page contains a Script manager as well.

I have an updatepanel with a radiobuttonlist, which looks like this in my markup code:(also, I tried specifying the AsyncPostBackTrigger with the specific eventname "OnSelectedIndexChanged" - no succes either).
[Code]....
In code behind, loads of things happends. But the primary important thing is this method which is being called:
[Code]....
Now, in each postback this is set as a datasource (it is not loosing its datasource because of some timer).What my problem is: Even though the Page_Load event is being fired and I can see the datasource has changed, the content I see in the radiobuttonlist stays the same!
I want to display the text entered in a textbox on a label character by character. I.e, if I enter a character in textbox, I need to display that character in the label. Up to the length of the textbox, this procedure has to done for the label also.

onclick of Add Topics button, both the update panels are getting updated. I want only the inner update panel should update.
I either don't understand or I'm not using AJAX right. I'm running a long report. I'd like to have a label to show the user that the "Report Running", then, that the report has finished. But, when the user runs another report, I'd like to have the label that shows "Report Finished!" to clear so that you don't have "Report Running!" and "Report Finished!" on the screen at the same time. But, the label will not clear???? I get both lables showing. What am I doing wrong?

In my webpage I have an updatepanel and a button that updates the Label.[Code]....

If the button is inside updapanel, nothing happens when I click the button (Label is not displayed), but if I move button outside the panel it works. (Button must be inside updatepanel and ofcourse no PostBackTrigger)
I'm using ASP.Net 2008 and C# and Ajax. I have wired up my ajax updatepanel to update the buttons within them in the gridview control's RowCommand event. However, at the end of this event, I call the Response.Redirect(commandArgs[2]); to open either Word or Adobe docs that user selected. And this line of code stops my Ajax updatepnael to update my 2 buttons' enabled properties. I thought maybe there is another way to open docs that won't interfer with my Ajax updatepanel and what will that be?

GOAL: on a web page (vb.net) content in a placeholder will refresh with a different .ascx (user control) every 30 seconds (rotating 3 in total) and of course i dont want to refresh the whole page, just the placeholder.
I'm new at AJAX (that's my first problem - lol)
I set the timer up to call a function, but not sure how to go about refreshing the placeholder with a different ascx file. I'm sure i'll be using UpdatePanel to do this, but haven't been able to figure this out. Easy to replace a value in a label using AsyncPostBack trigger, but nothing on how to achieve this.
I have the following code -
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always" >
<ContentTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl="~/captcha.aspx" /> [code]....
Problem is the lblname1, lblphone1 and lblemail1 do not update on the page with the new values, if I step into the routine I can see the values and a success asssignments but on the page I get NO values. I removed from code the updatepanel and I get the values on page.I also tried conditional updatemode with no success but again I get NO values.
I have a asp.net listbox server control that is connected to a jquery plugin that can handle a client side click event for each of the checkboxes it renders.
Whenever I click on a checkbox the click event gets triggered and I make a call to
__doPostBack("UpdatePanel1", ""); so that i can update the updatepanel and rebind the checkboxlist inside it.
is it possible to do the rebind first, and then update the updatepanel? how do i do that? because now, the rebind happens on the second time i click on the checkbox.

I am currently using a asp.net 2.0 with visual studio 2005.
I am trying to build a web application using ajax.
but when I drag the ajax updatepanel on asp.net page it is not resizable,so how should i put other controls on it?
there are times when i can't understand why something can't just be simple. Of it is, but i'm not looking in the right place for the obvious answer.
Given a simple MVC 2 site with a master page. This master page has a login button and a text label for the currently logged in user.
An action link on the master directs to a login page. Simple 2 text boxes and a button. When the correct userid and password are given to the controler. I want to update the label on the master with the name of the customer. i cannot find any simple way to do this. I'll use jQuery, code on the view, code in the controler. I'll even take a redirect to force the master to reload. The Index page can be redirected to, but this still leaves me with a problem using "Logout" redirect to Index when you are on index. The master page does not reload.
