AJAX :: GridView Inside AccordionPane : Control Toolkit?
Feb 23, 2011
I am facing a problem concerning gridview inside AccordionPane:using Visual Studio .Net 2010 designing Asp .Net Web Application (.net 4) using ajax Control toolit (.net 4 and have tried with .net 3.5 version)
When I insert a gridview inside the an accordionpane content everything seems OK. However, changing the SQLDatasource configuration, or even the Griview's colums, no code is written in the aspx web page. That concludes to the fact that: in design mode i can see everything, at runtime nothing appears. In designer's view the gridview renders fine, but when at source view, nothing is written. If I change gridview's and SQLDatasource position outside the Accordion, everything is working perfectly, including the sourceview update in the aspx page.
I add a gridview into a accordionpane in a accordion. And I bind data to this gridview and define a column as a datakeyname and make it un-visible. However when I get the datakeys[index] in the behind code, there is an error that "Index was out of range".But I am sure the index is not out of the range, and when i debug i see the count of the datakeys is 0
I am having a problem setting up the width and height of my textbox inside of my accordion panel. Does not make any sense because my code executes correctly but then does not change the value of the control on client side.I pass a control into this function and iterate through the control to locate more controls.
now i want to make the top corners round for the pane1 only. can any one please guide me how to do it?? how can it be done by ajaxtoolkit RoundedCornersExtender?
I am Getting the following error using the Numeric UpDown Control from Ajax Control Toolkit. Assembly 'AjaxControlToolkit, Version=3.0.30512.20315, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' contains a Web resource with name 'AjaxControlToolkit.NumericUpDown.NumericUpDownBehavior.debug.js', but does not contain an embedded resource with name 'AjaxControlToolkit.NumericUpDown.NumericUpDownBehavior.debug.js'.
I am creating nested accordion using the object model and have created buttons in the inner accordion's accordion pane. The buttons look great but issue is that the buttons does not fire thier click event. They just do the postback of the page and ignore the event.
I want to show a pop-upextender on the pre_init event but all my panes are added dynamically so it does not give any rows.
How can i get other controls on my webpages (eg. Forms, Gridviews, TextBox, DDL's, etc...) to STOP rendering dynamically generated ID's from the AJAX Control Toolkit?
I have been able to successfully download and implement the AJAX Control Toolkit MENU within my .master page using an XML sitemap data source as well as changing the CSS properties to suit my layout and design. It now renders the page (in Source View) with the more robust HTML UL, LI tags, etc....
However when i add a new Gridview into the Content of a new page (using my master page), the View Source shows the Form ID & GridView ID has been dynamically changed which i'm sure is because of the AJAX Control Toolkit.
Am i supposed to remove something from my AJAX Control Toolkit to stop other controls rendering new ID's?
As the ID's and names change when the page is rendered i cannot CSS Stlye items, use code behind with my standard names. I get errors saying the Objects are NULL as they cannot be identified.
Me using Vb.net and Ajax control tool kit with Database Sql server.My problem is that When I select one Radiobutton list it genrates only one row in gridview and when i select another button it throws error like ".non MS DOM browser is undefined."and sometimes " document.getElementByid() is null or not an object" OR ".javaScript_dopostback.".I have few componets on my page
1. RadioButtonList Which is placed inside Update panel1 first. 2. GridView Which is placed inside Update panel2 second..and Gridview generated five Textboxes Dyanamically in which i have used autocomplete extender with one textbox. 3. I have also used Ajax tool kit extender for calender control. 4. I am also using Jquery and master page too. 5. i am generating new row on textchange event of one of the textbox in grid view.So how can i do all the above functionality properlly.

I have 2 tables, call them stock and visit. Stock contains a list of standard products (code and description columns). Visit contains a list of products used during a visit (product description column amongst others). When a user adds a product to the visit table they can either select a standard product from the list or select a product code and amend the description, e.g. they could select "paint" and change the description to "blue paint". The new description will only be relevant in the Visit table. This all works fine.
I have an editable gridview which lists the products used during a visit. There is an Ajax control toolkit combo box in the EditItemTemplate which allows the user to select a different product. If the product exists in the Stock list then everything works fine. If the user amended the description (e.g. changed "paint" to "blue paint" when they added the product to the Visit table I get the following error.
'ProductDescription' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
I presume this is because the amended description won't exist in the standard list of products. How do I add the amended description to the combo box list? I've tried using the RowEditing event but can't reference the combo box in the EditItemTemplate.I think what I want is something along the lines of [Code]....
Combobox markup below
<asp:ComboBox ID="ProductDescription" runat="server" [code]...Answer in vb preferably.
I'm using an accordion control with a textbox to get data that I'll use later to get values for a ObjectDataSource, that use the data of the textbox as ControlParameter.
my problem is that I'm getting a 'Not found control error...' because the textBox is inside the accordion how can I reffer the control into my ObjectDataSource?
Referring to the following: Ajax Asyncfileupload doesn't work as soon as I put it in a control I am having the same issue. I am not using a Master page though. I have an AsyncFileUpload control in a Panel, within an update panel.
I hv used datadridview to display certain info. to the user from db. A column has too long text creating sizing problem for the datagridview so i hv used ajax hovermenu extender to display (keeping the width fix) the extra text which is working too!!! but my problem is that the popup should display when i hover over that column while what i m getting now is that it displays as i hover over the gridview....
i tried the all popup positions property but not displaying as i wanted...
I've got a fileupload control inside of a gridview so that each row (item from the database) can have an attachment associated with it. I've got a button next to the fileupload control (besides the default browse... button to select the file) to actually take the file and upload it to a file server. This works great if I use this button "Upload". However, underneath my gridview I have another imagebutton that is outside of the gridview, its just sitting on the form / page. The idea of this "Update" button is when end users make changes to the grid I can simply loop through the grid and update the values they have entered to the database. This also works great.
Now here is my issue assume a user has 3 rows in the grid view. On 2 of these rows he decides to add an attachment but he never clicks the "Upload" button he only uses the standard browse button to select the file. Now instead of clicking the "Upload" button that is on the grid view he ends up clicking the "Update" button outside of the grid thinking that it will save his attachments. So I decided to write code to grab the fileupload control from the grid using .FindControls("NameOfFileUploadControl") in my Update button loop where I loop through all the rows. Then I check if myFileUploadControl.HasFile property to see if there exists a file and if there does upload the file then continue with the code.
The issue is when I click this "Update" button .HasFile always returns false even though I can see the text string of the path in the fileuploadcontrol textbox (the standard one next to the browse button). Is it because this goes back to the page load event and checks if it is a post back? What causes this and how can I fix it? Im adding some code because im still confused with this
Protected Sub SaveGrid() For Each Row As GridViewRow In Me.gvLineItems.Rows Dim f As FileUpload = CType(Row.FindControl("fuAttachment"), FileUpload) 'todo: this part is not working If f.FileName.Length > 0 Then 'returns 0 always 'this returns 0. end if if f.HasFile() then 'this also returns false end if Next End Sub
This method gets called on a click of a button. The fileupload control is in an of a gridview that is wrapped inside of an UpdatePanel:
The Ajax control toolkit tab panel automatically inserts a space by all four corners of the body. For example, go to http://www.asp.net/ajax/ajaxcontroltoolkit/Samples/Tabs/Tabs.aspx and look at the TabPanel on the page. The is a space before "Signature:" and "Bio:" labels. How can I set the space-width to 0px; in the tabPanel body?
When I click the button to open the modal popup it shows the popup but then continues and forces a postback causing the page to reload and the modal popup to be hidden again.Here is the markup for the control:
I'm trying to use the Calendar control in a local intranet enviroment, so I need to put all the Javascript files locally, I've downloaded the Ajax Control Toolkit 40412 source code and extracted the Scripts from
"..AjaxControlToolkit_9c860ac12ae9SampleWebSitesAjaxClientWebSiteScripts",so I write the following code

the problem is the items text in the combox box is having a square beneath at the second character which is hindering the visibility of the list. but the square is not appearing in the text area.
Adding an Accordion only creates the outer most tags. I then have to add the headercssclass, contentcssclass etc. info. Then i have to manually add <Pane> tags, and then add Accordion Pane controls. Using VWDE 2008, is there a way to customize the control so that adding the Accordion control automatically adds this other info? Ideally with 2 Accordion Panes to start, but even just getting the various Accordion properties and the <Pane> tags added would make it much more <Pane>less!
