hello
Reading this article on TreeView control...[^], it shows how to either bind a xml file on disk to TreeView control via "XmlDataSource"
<br />
<div><br />
<asp:TreeViewExpandImageUrl="Images/closed.gif"<br />
CollapseImageUrl="Images/open.gif"ID="TreeView1"<br />
Runat="server"DataSourceID="XmlDataSource1"><br />
<DataBindings><br />
<asp:TreeNodeBindingDataMember="Category"<br />
ValueField="ID"TextField="Name"><br />
</asp:TreeNodeBinding> <br />
<asp:TreeNodeBindingDataMember="Description"<br />
ValueField="Value"<br />
TextField="Value"><br />
</asp:TreeNodeBinding><br />
</DataBindings><br />
</asp:TreeView> <br />
</div><br />
<div><br />
<asp:XmlDataSourceID="XmlDataSource1"Runat="server"<br />
DataFile="~/Data/Categories.xml"><br />
</asp:XmlDataSource><br />
</div><br />
My question are:
1. how can we bind an in-memory (not on disk) XmlDocument object to a XmlDataSource? and thus TreeView control? In the article author has suggested an alternative - OnTreeNodePopulate event - however, this is not suitable for my case as my whole list/hierarchy is loaded in one go, not once-per-node.
2. how can we set navigation Url? in standard "web.sitemap", you can do this with siteMapNode's "Url" attribute. But now that, as in above example, uses my own custom Xml... how do we do this?
Thanks
dev

Hi I am populating a Dropdownlist using clientside script.Later, when I am trying to access the dropdownvalue from server side code,it's coming blank.
I have tried the following:
string val=DropDownList1.Text;
I have also tried
string val=DropDownList1.Attributes["value"];
But none worked.
Please guide me to solve this.

If you are populating the Dropdown using client side script(JavaScript), then you cannot read dropdown value at server.
Dropdown clears when page post back.
If you need to read the value, save the selected value of dropdown into the hidden text box, using JavaScript(Before Page Post Back). Now read the textbox value.

Hi fellow coders,
I'm trying to do a HTTP GET request but I get this error: Unable to read data from the transport connection.
Below is my code:
Dim web As New System.Net.WebClient
Dim stream As Stream = web.OpenRead(URI)
Dim reader As StreamReader
reader = New StreamReader(stream)
strResult = reader.ReadToEnd
Note I cant do POST as the URI does not support that.
Thank you in advance.

This question has NOTHING to do with ASP.NET

You never do a webclient request in ASP.NET? well, then too bad...

Just because it's *possible* to do something in ASP.NET, does not make it an ASP.NET question. If I can do it in a winforms app, then it's just a C# question.

Some people are just not helpful are they?
If you got nothing to say, then dont reply!
If I'm wrong then you can at least point me to the right direction, you dont have to sound so rude you know!

|

FYI when people are incapable of even working out where to post a question, I point them in the right direction BECAUSE a question asked in the right forum, is more likely to get an answer.

string strUrl = "http://www.abc.com/a.aspx";
Uri url = new Uri(strUrl);
string strFinal = url.ToString();
WebRequest objWebReq = WebRequest.Create(strFinal);
WebResponse objWebRes = objWebReq.GetResponse();
Stream objStream = objWebRes.GetResponseStream();
StreamReader objStreamReader = new StreamReader(objStream);
string strHTML = objStreamReader.ReadToEnd();

Hi Aman,
Thank you for your help.
I have tried your solution, but I'm still getting "Unable to read data from the transport connection" at this line objStreamReader.ReadToEnd
The URI is ok though, please advice...

WebClient class wraps all these nicely. So you don't have to use WebRequest or WebResponse explicitly unless it is really required.

I have a large array of Imagebuttons on an ASPX page, that have the URL set depending upon the value of a variable
The value matches the name of the ImageButton as below. Rather than the convoluted code as below is there a way to somehow dynamically change the button - something like
ImageButton[mapflag].ImageUrl="warning.gif"
if (mapflag == "TV1_ANALOGUE") TV1_ANALOGUE.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV1_DTT") TV1_DTT.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV1_DTH") TV1_DTH.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV1_FM") TV1_FM.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV1_LINKING") TV1_LINKING.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV1_ISN") TV1_ISN.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV1_EXTEND") TV1_EXTEND.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV2_ANALOGUE") TV2_ANALOGUE.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV2_DTT") TV2_DTT.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV2_DTH") TV2_DTH.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV2_FM") TV2_FM.ImageUrl = "warning.gif";
Many thanks for any help

Building a map of strings to buttons is about your only option, unless you have an event and can make the button the tag for the event that causes this to happen

Well, it depends on the host, if they have SQL Server installed, and how they give you access to it, to set up your DB

I believe you want to mean interaction of Dropdown List in your web page . Am I correct ?
You can easily implement that, On the Selected Change Index of First Dropdown list , Load the data of Second dropdown list.
Suppose, your first Dropdown contain all the Country name, and on selection of country you want to show the states of that country on the second dropdown list, then call a Stored procedure on selection index changed event of first dropdown list and pass the country name which returns all the state name in a dataset and bind that with second Dropdown list.
Hope this will help you to go ahead.
Please let us know if any more issue.

I took advantage of some code I found on these forums and have created a form that has a nested gridview. The first gridview is bound using the SqlDataSource and on the OnRowBound event, bind data to the nested gridview. Then using JavaScript i hide the nested gridview until the user clicks on an image. The code I found for the javascript nested grid view is here. I then added code to highlight the selected row in the the first gridview. What i need to know is how would I go about adding code to make it so that I can do the same for the nested gridview?
Sample code
protected void Page_PreRenderComplete(object sender, System.EventArgs e)
{
//GridView nestedGrid = (GridView)GridView1.FindControl("GridView2");
foreach (GridViewRow y in GridView1.Rows)
{
y.Attributes.Add("onclick", "setSelected(this);");
}
}
function setSelected(selRow)
{
// alert(selRow.rowIndex);
var tbl = document.getElementById("GridView1");
for(var i = 1; i < tbl.rows.length; i++)
{
if(selRow.rowIndex == i)
{
selRow.style.fontWeight = "Bold";
selRow.style.backgroundColor = "Yellow";
}
}
}
But once i moved to child grid that time Click event of parent Grid cell does not fired so all highlited row of parent grid gone.
so how to solve it
