If I click this button it is working OK (it will respond with a PFD file so no HTML is sent back to the browser), but if I click another button on the page (which makes a full postback) the LinkButtonPrint will not have the inner content, it will be rendered like this:
<a href="javascript:__doPostBack('ctl00$LinkButtonPrint','')"
id="ctl00_LinkButtonPrint" onclick="StartLoadTracking(this, 'Loading...');"></a>
If I remove the LinkButtonPrint.Attributes["onclick"] = ... line from Page_Load everything works fine (except my js function is not called, but that is normal).
What am I missing here?
EDIT
This is duplicate of asp.net Link button image not visible after postback.
My combobox and asp:fileupload and imagepreview all are inside update panel , my combobox is doing postback after which my image disappears.... how to retain back image after postback ?
In [URL] .... if I remove input:file and put asp:file then it will be possible ... here's all code:
using System; using System.Drawing; using System.IO; using System.Web.UI; using System.Web.UI.WebControls; public partial class Default3 : Page
So this might be a fairly specific issue but I figured I'd post it since I spent hours struggling with it before I was able to determine the cause.
<asp:GridView ID="gvAttachments" DataKeyNames="UploadedID" AutoGenerateColumns="false" OnSelectedIndexChanged="gvAttachments_SelectedIndexChanged" runat="server"> <EmptyDataTemplate>There are no attachments associated to this email template.</EmptyDataTemplate> <Columns> <asp:TemplateField ItemStyle-Width="100%"> <ItemTemplate> <asp:LinkButton CommandName="Select" runat="server"><img src="/images/icons/trashcan.png" style="border: none;" /></asp:LinkButton> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView>
In the ItemTemplate of the TemplateField of the GridView I have a LinkButton with an image inside of it. Normally I do this when I have an image with some text next to it but this time, for whatever reason, I just have the image. This causes the UpdatePanel to always do a full postback.
i have update panel with some wierd ie 7 issue, when you click a a - z link on the below url, after the async postback the linkbuttons disapear until you mouse over, not sure why this is happening.
I have a Link Button in asp.net C# inside it i set an image...........when i click on image its works... But when i click on text it donts work , here is my code
However, if I change the text of the LinkButton in the code-behind, I lose the image.
btnTest.Text = "New book name"
I have tried removing the LinkButton's controls in the code-behind and recreating the image along with changing the text, but it still doesn't work. I get either the image or the text but not both.
btnTest.Controls.Clear() Dim NewImage As New Image With NewImage .Height = Unit.Pixel(8) .ImageUrl = "~/DropDownArrow.png" .Width = Unit.Pixel(10) End With btnTest.Controls.Add(NewImage) btnTest.Text = "New book name"
How can I change the text in the code-behind and still retain the image as well?
I'm using a lot of LinkButtons in my web application with text and images inside them. All LinkButtons are set with a ToolTip and all images inside the LinkButtons are set with an alternate text.
The problem is that in Internet Explorer the alternate text of the image is shown instead of the ToolTip of the LinkButton. In Firefox this problem doesn't exists, it always show the ToolTip of the LinkButton.
I have a problem with password textmode...When debugging my .aspx page , the text entered in the password box disappears...In single or multiline mode, there is no problem..the text disappears when an event occurs(for eg. when a button is clicked)....So, I have to retype the text in the password box to insert the data into a databsase..Why this problem occurs?..
It is, as you might have guessed, the text box from an on screen PIN pad. Javascript fills in the values. The page is posted back every five seconds (using an update panel if that matters) to update various other unrelated items on the screen. This works just fine. However, when I convert it to a password text box, like this:
Then whenever the page posts back, the text box is cleared out on the screen and the textbox is empty (though during the timer event, the value does make it back to the server.)
I have an asp:UpdatePanel in my .aspx page.Within the panel I have placed an infragistics ultrawebgrid control.Upon clicking a button (placed outside the panel) , I have to export the data in the grid to excel.I am using
UltraWebGridExcelExporter(Infragistics object) for this. The export will occur only with full postback.For this I have added a PostBack tigger for the button to the update panel.But once the export is complete, if I change the selected item in a dropdownlist(Autopostback="true") in the same page,the updatepanel gets invisible.
I've coded myself into a state of confusion. I have a form with a postal code TextBox and a country DropDownList both inside an UpdatePanel. When the selected country is changed, the DropDownList auto posts back and sets the regular expression used for validating the postal code. The country DropDownList also has a RequiredFieldValidator. The first item in my DropDownList is empty (Value = Text = String.Empty) and when I select this item, I momentarily see the RequiredFieldValidator appear and then disappear. It seems that the client side script is displaying the error message, but then after my partial postback it disappears. I can see in the country DropDownList's SelectedIndexChanged event handler that the RequiredFieldValidator has IsValid = false, so why doesn't the error message stay visible?
I have a gridview where in the users are allowed to edit certain data and there is an update on top of the page which will send out all the changes made inside the GridView. But, the problem is , as soon as the update button is clicked, the grid disappearsand no update is made. This problem occurs when the size of the data on the page is huge. When we have less amount of data on the gridview, It does update. But, when there is a huge amount of data on the gridview, it does not. We have tried to increase the page size on the server, but to no use.

my data in gridview4 disappears when i click add to cart it shows no data again i have to pass a query from gridview 3 and then gridview 4 appears and then again if i click on add to cart in gridview 4 it shows no data.
I am writing a web page to show image (image is dynamically generate by .Net charting) in a web. I have used the asp.net web forms URL routing to navigate to this page. Once I use the URL routing the image appear on the page. Anyway this is working fine for normal page browse.
I have a datarepeater inside which I load a gridview. After the grid's binding is done I create an extra header line to group the columns (that's the only way I could do it, I couldn't figure a way to add an event for a control inside the repeater).That works fine and the page displays perfectly.However everytime I do a postback from other controls, I lose the 2nd header and 1 extra empty line appears at the top of the gridview
have an ASP.net 4.0 page containing a GridView, where during the Page_Init event I'm dynamically adding BoundField columns to the gridview. I also have some custom sorting and paging methods that I use with this gridview, which result in postbacks on the page. In Chrome, Firefox, Safari, and Opera the gridview behaves as expected. HOWEVER, in IE 6, 7, or 8 when I click to sort a column in the gridview, or go to the next page of results in the gridview, it does not bind on postback, returning nothing back to the browser. Again, in anything but Internet Explorer, paging and sorting (frankly any postback event) brings back the gridview in its expected state. I only have the problem in IE. Relevant snippets of my code follow, where you'll see my Page_Init event calling a method in my WebFunctions class to add the BoundField columns for the table I pass to it, and my Page_Load event that calls the method in the user control responsible for binding my dataset to the gridview. Initial page load works in all browsers, but postback loading of the gridview only works in non-IE browsers.
The Crystal Report worked fine in the localhost,but when i deployed it,the images disappeared, and instead of this appeared Red X image,and The Print and Export buttons didnt work too Note:i deployed it on the internet Not IIS
The first step to reproduce the behaviour is pasting a specifc text from a PDF document into the HTMLEditor:
After that, select the text:
And then, click the Justify button. The selected text simply disappears:
The HTML code generated by the content:
The same happens for other texts like (also pasted from the same PDF):
The correspondig HTML markup generated by the HTMLEditor:
It seems like HTMLEditor has problems with some characters like " or subscripts. If the same texts are pasted into Word and then copied into the HTMLEditor, it works ok and the text is justified correctly.
Actually I have Multiple update panels on page, which update different values on server but the problem is that I have textbox to which I attach javascript class for datepicker on Load event.
