Web Forms :: Value Of The Textbox Is Accessible During Page_Iniit?
Apr 1, 2010
lets say I have the following code:
[Code]....
So - to start with textbox1.text is set to 1. But - If I do a postback, the value of textbox is lost - it's just empty. I need to pick up the value of the textbox during "DoThis()" but it only works the first time round.
Surely the value of the textbox is accessible during Page_Iniit?
I'm doing somehting stupid here.
(And BTW - I have to call DoThis from page_Init as that method also adds other controls to the page but I need to get this code working first)/
i'm using VS2005 and when i drag and drop an image button, i can't access it from code behind. the following is an example of an unaccessible imagebutton
I have an asp.net website in which users can submit reports. Another tester and I tested this page at the same time and when I went to review the information I submitted, it displayed information that I didn't submit. It displayed the info submitted from the other user.
I use session variables for these values. I don't understand how this happened? What can I do so each user can individually submit their information without overlapping some one else's information? The plan is for multiple users to be able to use this page to submit their weekly layer reports.
The first example of code is how I add the session variables from the textboxes.

The second one is how I display them in labels on a confirmation page.
I have a GridView and a TabControl. On click on the row of grid, I store the EmpId in a hiddenfield in javascript. Now in Page_Init, I am trying to load a usercontrol for a EmpId stored in hiddenfiled. But I am not able to access hiddenfield value in the Page_Init. It display empty. If I have to load the usercontrol during Page_Init, then I have to access the HiddenField value first and it is give problem.
I'm trying to keep these questions seperate for people searching after me, .
I have the following code on SelectedIndexChange of GridView1
[Code]....
I have a drop down list that you can choose values from, and depending on which item you pick GridView1 changes, this all works correctly, and if I select one of he rows the SelectedIndex changes. My problem occurs when you choose a different value from the drop down list, GridView1 Changes accordingly, and by default a record is selected. But selectedindexchange is never fired again until I manually select another record from the gridview which is a problem.
I have a gridview, whose columns I am dynamically binding. There are two fixed columns, one is a button field and another is a template field containing an image. The other columns might vary in number and behaviour, so before binding the grid, I am removing all columns of the gridview except the button field and the template field. But after doing this, if i try to do a findcontrol for the template field(Image column), it is notgetting the control. Means while removing the other columns, this image control also getting removed.Below is my code:
[Code]....
Now, after this i call the databind method. The problem is with the for loop, where I am removing the columns after the image column. And I am not able to find the control after that.In rowdatabound i am trying to find the control like this:
I am using MS Chart Control in my Web App,after some time I got the issue "The temp directory in chart handler configuration is not accessible" in Live App,even though my web.Config file is containing every thing related to charts like...
<add key="ChartImageHandler" value="storage=file;timeout=20;" /> under <appSettings> <add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false" /> under <httpHandlers>
After much research, no solution can be found to do what I want by combining these two controls. Currently, I have a repeater control which, in page_load, takes the querystring and queries the database accordingly, puts the resulst in a datatable, and binds the datatable to the repeater. Everything works fine, no problem there. It's just that I have many columns coming from the query and there are many rows as well. So, I thought it would be easier to incorporate the accordion, so that the header of each accordion pane would show some unique fields (name, whatever...) as the header, and the rest of the many fields in the content. This way, there would be many closed accordion panes showing the name from the row returned. If the pane is clicked, the pane would open and show the rest of the results.
The problems I've had are that the repeater is not accessible from the code behind if it is inside the accordion. But I'm sure I wasn't doing it right anyways. I'm just trying to have an accordion that has as many panes as there are results from a datasource. If there is something other than a repeater that you can suggest, or the correct way to incorporate the repeater in the accordion to do what I want, suggest whatever! I just need to format how the results display how I want, unlike a gridview (I used tables in my normal repeater, and that worked fine, I just need to get that repeater to work inside of the accordion).
(and I know this isn't the section to ask about the accordion, but what is the AccordionExtender? It's not in the toolbox, and I can't find much online. It won't be recognized by Visual Studio, so I don't know what to do. If I could get that, I feel like it could solve my problem, as I found a possible solution online) I don't need to post my code, as it's a simple repeater, and trying to integrate it within the accordion isn't working no matter which way I try since I can't DataBind() in the codebehind. And yes, I tried to FindControl within the accordion but it wouldn't find the repeater.

I have been doing dynamic PDF creation via ASP.net for some time -- in the form of HTML to PDF conversion. It works well for us, but we have accessibility requirements from the State to make everything is accessible. For static PDFs, we simply "tag" the files manually using Adobe's accessibility tools. Of course this does not work for dynamically created files. PDFs that I create dynamically fail the Acrobat Pro Accessibility test.
want to create PDFs dynamically in ASP.net, but producing PDFs that are tagged and can pass the Adobe Accessiblity test? I have researched many components, but none that I have found support tagging.
I am getting following error each time I tried to select database. The database 'DB Name' is not accessible. (Microsoft.SqlServer.Express.ObjectExplorer)
Note: My OS is Win Vista.
When I tried to open SQL Mgmt Studio as Run as administrator than I can able to access database properly.
why it is giving error.
I am also getting following error when my asp.net application is trying to access database.
Cannot open database "DBName" requested by the login. The login failed. Login failed for user 'PCNameabcd'.

I have developed a WCF .NET web service. It has evolved from a console application, hence some shortcuts were taken in VS 2008 rather than establishing the project from scratch as a WCF Web Service.
I have a page that i created a few weeks back.. had a few controls on the page.. everything worked and works great. Now this past week we had to me some changes to the page, adding a few more controls to the page.. the issue is that now, all the new controls.. (standard .net controls within VS2008) are not accessible from the code behind..
Example, if i add a textbox today to the page.. when i go to the code behind and begin to type textbox1. intellesense doesnt do anything.. and if i complete the line i get a wavy line under it..
In order to gain access to the textbox i have to add this to the code behind
I have an ajax tab container in an aspx page. Earlier I had 2 tab panels in the tab cotnainer. Now I want to add third tab panel. I could add the third panel but I am able to access the third panel, i.e. When I click on third panel, the panel is not shown(I didnt even get the handy cursor when i place the cursor on the third tab panel name).
In my namespace I can have public classes which are accessible to all other pages in my namespace. How do I go about having public functions? Do I have to create a class with the functions in it? Or is there an easier way?
I have a web page that I am converting from classic ASP to ASP.Net. There are a bunch of "Select" controls (DropDown Boxes) that I am changing to DropDownList controls. I have set the "runat='server'" in all of these controls. However, when I go to the code-behind, they are not visible/accessible. I have tried to "clean" the solution and rebuild it and the controls still won't show.
My purpose is to modified some data only for current page in a gridview. I call this function in page load and GridView_PageIndexChanged events. When it's called in page load event, it works fine. But when it's called in PageIndexChanged event, only the rows on the first page in GridView are looped through. For example, if I click page 5, the rowStartIndex becomes 100 = 5 x 20 (my pagesize). The if condition becomes itemsRead >= 100 andAlso itemsRead < 120. But after itemsRead is increased to 19, the For each gridViewRow loop stops and the if condition is never satisfied.
