Web Forms :: Treenode Value Exists - Unable To Find
Jun 29, 2010
I have a web page, I am adding treenode value from database. I need to check if any value is already added in node then childnode value should be added in the same parent node. In vb6.0 we have something Key of the node, but here I am unable to find. Here we get only text and Value for any Node.
Can We set Relationship here like tvwNExt, tvWFirst like vb. I am unable to find in ASP.NET I have a requirement where I need to go through in loop and set the parent Node, once and then child node. But due to loop its add parent node value everytime.
I have a control on a master page called "panel1". I would like to access it from my Javascript on the content page. I have tried var panel1 = document.getElementById('<%= panel1 %>'); It doesn't work since it is on the Master page.
When there is no DataSource assigned to my grid it doesn't render which is great!
When the datasource is empty it doesn't render - also great :-)
I am implementing some custom navigation so i want to know if there is a property that tells me if the dataview is rendered? If it is rendered i can show my custom bits otherwise i don't.
i have a site that will enable users to download an ebook file.i have successfully built architecture to enable users to download pdf and txt files, but it won't work when i try with a .mobi file, even though i know the file exists.the site works by allowig users to upload their work as .doc, .docx or .odt. once it's verified, the site publishes it as .pdf, .txt and .mobi and makes it available for download. the download code is...
(there are also versions with .txt and .pdf) the file definitely exists at the location in .txt, .pdf and .mobi extensions. however, the .mobi version simply won't work i get an error 404 resource not found. mystifyingly, the pdf and txt versions work perfectly.

I am unable to find any control in row editing event of gridview that i have put in edit template. I have to populate the dropdown control so that in editing the user can select value from the control.
How ever i can access the controls in row updating .But i need it in row editing event.
I would like to check whether a folder exists or not if not create. I'm sure this folder exists, but for some reason I get "false" when I check with "Exists" method.
The only reason I think could be because of the W: drive? I moved this application to production site and even there it returns false.
while I'm type in Windows explorer on my localhost and on the server "W:/Webs/ASPPages/cropper/uploads" it opens this folder. So my localhost and IIS server has W: mapping.
for test I tried to create the folder then it says can't find the path...
userFolderName = @"W:/Webs/ASPPages/cropper/uploads" //I also tried @"W:WebsASPPagescropperuploads" //I also tried @"W:WebsASPPagescropperuploads" //I also tried "W:\Webs\ASPPages\cropper\uploads" DirectoryInfo dirInfo = new DirectoryInfo(userFolderName);........
i am using vs2008 for web page. i want to see my assembly name. For this i am right clicking on solution/project name but i am not able to see assemble name .
I am able to find the controls of all of these Lables and TextBoxes accept the edateTB. This is strange to me because it is in the same view as the sdateTB. So why would edateTB return NULL when I try to use FindControl on it and sdateTB return the correct control?
Here is the codebehind where I am getting this error. There is more code in this, but I just thought I would include everything up to the part where I get the NULL error.
Couple of days ago I was creating site where i have placed a login control taken from the Login Tab in Toolbar, but today i am unable to find it there, see the attached snap, where the Login Control Is ?
When I run the website locally using my VS, everything works.
I am calling a function inside a dll using P/Invoke. DLL is in C++ and it works.
When I deploy the website on IIS, I get the error message Unable to load DLL 'SolvingProbelm.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
The dll resides inside the bin folder. App pool is Classic and .net 2.0
What am I missing / doing wrong here, causing that exception?
My observations so far:
In the Reflector these resource is visible, and named as MyNameSpace.scripts.jquery-min.js In the AssemblyInfo.cs file of the project, the file is registered as:
[assembly: WebResource("scripts/jquery-min.js", "text/javascript")] The file lives in the 'scripts' directory
On a sidenote, I've tried using Page.ClientScript.GetWebResourceUrl() but this generates an URL without checking if the resource exists. It also seems WebResource.axd is not mapped in Web.config at all.

i am trying to upgrade my WEB applications from .net 2.0.0.0 to 3.5.0.0. When i open my solutions in VS2008, it prompts me to update the framework to 3.5.0.0 .
But. Not all the dlls are getting updated. some dlls are getting updated to 3.5.0.0 but some remain in older version 2.0.0.0. Also, i could not find some dlls in 3.5.0.0 folder
For example the following dlls are there in 2.0.0.0 but not in 3.5.0.0
My question is whether it is possible or not to extract the "is_tube_mailer" field from the Treeview's Treenode. I attempted to cast the node.DataItem to an Xmlnode, however that only seemed to work in the TreeNodeDataBound event. I need to do this within a Button.Click event routine.
