how to read selected node and its parent node values for treeview in asp.net in JAVAscript.
View 3 RepliesI have my repeater loading in plain text from a database right now e.g.
<td>
<a href="<%# DataBinder.Eval(Container.DataItem, "URL")%>">
<img alt="<%# DataBinder.Eval(Container.DataItem, "AltTag_Thumbnail")%>" src="<%# DataBinder.Eval(Container.DataItem, "URL_Thumbnail")%>" />
</td>
<td>
<%# DataBinder.Eval(Container.DataItem, "Name") %>
</td>
My plain texts are image links and pdf URLs from a database table, in groups, in the correct order but I'm not sure how to render them correctly (sample image below shows what I am trying to render)
Is there any way to make a repeater template intelligent enough to render an "image link" OR "pdf link" based off the [type] column returned in the record?
table:
pk
Name
Type (image or pdf)
URL
Description
URL_Thumbnail (if image)
GroupId (associate these records to each other)
OrderNumber (order of these records within their GroupId)

View 1 RepliesIs it possible to read an .aspx-file from the filesystem, probably translate it into the Page-object and then render it into HTML? And then writing it back to the filesystem as a .html file.
The .aspx file on the filesystem is without the codebehind file. If possible provide me some example code.
On our site, we have our sitemap in this order:SiteName > SelectedProject > Path > To > PageWhere SiteName takes you to the very root page which is primarily to select a project and SelectedProject takes you to the project's homepage.Currently, in the Web.sitemap file, SelectedProject has a static name. How can I rename it to the name of the selected project, which can be obtained from Session("PRJ")?

Let's say I have a string that I retrieve from a DB like: "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et {{Hyperlink|navigateurl='/foo.aspx'}} dolore magna aliquyam."
This string may now get assigned to the Text-property of a label. What I want is to parse {{Hyperlink|navigateurl='/foo.aspx'}} and replace it with
<asp:HyperLink ID="IDLink" runat="server" Text="foo" NavigateUrl="/foo.aspx"/>
and assign the whole text including the HyperLink-Control to the Label.
Is that even possible? I think I could use reflection to create the control and set the properties. (the HyperLink-Control was just an example) But can I manage to insert the asp.net control back into the string to ensure the hyperlinks rendering as server contorl?
I hope you understand what I want. If not, feel free to post comments.
Edit1:
what do you mean by "assign the whole text including the HyperLink-Control to the Label."? can you xplain a bit, the reason for doing so ?
I think it won't work to assign the control into the string, because a asp.net control cannot be fit into a string.
After some thinking I found a way to achieve my goal. That would be to create a placeholder (I name it A). Therein some Literal control will be added. In addition I would create a placeholder (I name it B), add my Hyperlink into B, and add A into B. But I think is way to overkill.
The reason why I started thinking about this, was to gain access to Server.MapPath without replacing occurences in the string. I want to be able to use relative paths in my CMS, that get rendered like the NavigateUrl property from a hyperlink. Nevertheless I think my question with the dynamically creation is worth thinking about

I got a problem that is I want to render some controls dynamically but I don't know how!
I want to add some controls like this inside of view:
<%ModalPopupExtender mpe = new ModalPopupExtender();%>
<%mpe.ID="m"+Model.Serial.ToString();
mpe.TargetControlID = "l" + Model.Serial.ToString();
mpe.PopupControlID = "div1";
mpe.BackgroundCssClass = "modalBackground";
mpe.DropShadow = true;
mpe.OkControlID = "OkButton;";
%>
This is ok but my question is How can I render this control?
I have come across a requirement to dynamically show or hide asp.net web controls , html server controls. I want to do this through a configuration XML (as it would be easier to config). So each page /aspx will have a configuration xml.
Would it be possible to create a control (may be a custom control , to which i can attach the xml file). The control (lets says - call it sequencer) should decide which control should be ordered in which order and if the control has to be shown or not. Ideally this sequencer control should use the page events and take decision on rendering the child controls.
Some thing like this
aspx -
<Sequencer XmlPath=".." Id="S1" Runat="server">
<Textbox id="t1" runat="server" />
<Textbox id="t2" runat="server" />
<Textbox id="t3" runat="server" />
</Sequencer>
This is hiw xml config may look like -
<Sequencer Id="S1">
<control id="t1" sequence="2" show="true" />
<control id="t2" sequence="1" show="true" />
<control id="t3" sequence="3" show="false" />
</Sequencer>
So in this case t2 should be rendered first then t1. The control id in the xml and the aspx has to be same.
t3 should not be rendered at all on the screen.
Which page load event should I use.
how I can create this kind of a custom control that does the above for me.
We have an application where the controls are dynamically added to the form based on the logged in user,
This user controls related data is stored in the database. There is lot of logic in the code behind in the asp.net webforms which is so messy to maintain it, we are planning to re-write it using the MVC framework.
I would say there would be rougly 50 different forms based on the user logged in, is it good idea to create so many views and redirect to the appropriate view based on the logged in user, in some of the forms there might be minor difference like the order of the Control might change.

I'm populating a treeview dynamically. On OnTreeNodePopulate I call a sub and populate the Parent nodes. I do not want to populate the child nodes at this time. Upto this point it works fine.
Now I would like the user to click the parent node and then populate the child node. I tried to use TreeNodeExpanded, but that is called for each parent node, so that didn't work.

I am accessing this xml file by using LINQ to XML in asp.net by using C#. I am able to access all the attributes of an XML node by explicitly specifying the name of the attribute. I want to write query on this xml file which reads all the attribute values of the xml node (In our example the node is SERVER) dynamically means I want to write the query which can read the read the value of the attribute Name & ID from first node, only name from second row, Name, ID & Parent from the third row , Name & ID from the fourth row, Name, Parent & Value from the fifth row & only Name from the sixth row without modifying the existing code every time. Once I add one of the attribute ( for example if I add the attribute ID in the sixth row ) in the above xml file then I dont need to modify my LINQ to XML query. My query should dynamically fetch the total number of attributes & display their values. Is their any way to do this ?
