You have already asked this, eventually, before. The answer is you need to learn to read the documentation and stop throwing things together hoping it will work.

i changed it little bit. I tried to use dataRelation before repeater get binded. that resolves the previous error but it gave different error says
Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Source Error:
Line 1222: objDA.Fill(ds);
Line 1223:
Line 1224: DataColumn c1 = ds.Tables["category"].Columns["ID"];
Line 1225: DataColumn c2 = ds.Tables["item"].Columns["catID"];
Line 1226: dRel = new DataRelation("categoryItem", c1, c2);
my code is:
void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
RepeaterItem item = e.Item;
if ((item.ItemType == ListItemType.Item) ||
(item.ItemType == ListItemType.AlternatingItem))
{
Repeater2 = (Repeater)e.Item.FindControl("Repeater2");
DataRowView drv = (DataRowView)item.DataItem;
Repeater2.DataSource = drv.CreateChildView("categoryItem");
Repeater2.DataBind();
}
}
the changed code is in this block:
objDA.Fill(ds);
DataColumn c1 = ds.Tables["category"].Columns["ID"];
DataColumn c2 = ds.Tables["Item"].Columns["catID"];
dRel = new DataRelation("categoryItem", c1, c2);
ds.Relations.Add(dRel);
Repeater1.DataSource = ds;
Repeater1.DataBind();
the "ID" of table "category" is the foreign key in "item" table and that foreignKey name in the "item" table is "catID". But the error is something wrong with those IDs.

Hi friends
I have defalut.aspx page in My web Application. I want to load dynamic content into this page.
for example if i have url "http://www.cricinfo.com" which contains html content right. so i want to load this content into my default.aspx page.
Please help me how to do it?

I think you can use iframe for achieving this.
|
|
|
|
|
You can use Streamreader to read the content and assign it to the control(Ex. Label) on your default.aspx page.
We successfully implent it. However we have the permission to access the data from another website.

It's an ASP.NET control, why couldn't you use it?
Why don't you show what you have done so we can help point out what may be wrong.

Sure. Thanks for the reply. Well these are the codes.
<asp:Repeater runat="server" id="Repeater1">
<HeaderTemplate>items<br /><br /></HeaderTemplate>
<ItemTemplate>
<b><%# DataBinder.Eval(Container.DataItem, "catagoryname") %></t>
<br><%# DataBinder.Eval(Container.DataItem, "catagorydescription") %>
<asp:Repeater ID="Repeater3" runat="server">
<ItemTemplate>
<br>Items: <%# DataBinder.Eval(Container.DataItem,"ItemName")%></t></t></t><%# DataBinder.Eval(Container.DataItem, "Amount") %>
<br><%# DataBinder.Eval(Container.DataItem, "ItemDescription") %></br>
</ItemTemplate>
</asp:Repeater>
</ItemTemplate>
<separatortemplate>
<br />
<br />
<br />
</separatortemplate>
</asp:Repeater>
I have these in my ascx page.

You won't be able to access the Repeater3 control from the ascx directly as a new one is created for each databound item.
If you handle the OnItemDataBound event on Repeater1 you'll be able to access the Repeater3 control using:
e.Item.FindControl("Repeater3")

Why not? See below.

Thank you for the reply but still it didnt recognize Repeater3..

You have not bound the nested Repeater so of course it will not display anything.
<asp:Repeater ID="Repeater3" runat="server" DataSource='<%# ((SiteMapNode)Container.DataItem).ChildNodes %>'>

Thank you for the reply but adding that line still couldn't recognize the Repeater3 ..

Please clarify what you mean by this.
The example was for a nested Sitemap, you will of course need to adjust it to your usage.

I am taking datasource from the dataset which i passed it to the repeater1.I also tried like this:
<asp:Repeater runat="server" id="Repeater1">
<HeaderTemplate>items<br /><br /></HeaderTemplate>
<ItemTemplate>
<b><%# DataBinder.Eval(Container.DataItem, "catagoryname") %></t>
<br><%# DataBinder.Eval(Container.DataItem, "catagorydescription") %>
<asp:Repeater ID="Repeater3" runat="server" DataSourceID="DataSourceMember">
<ItemTemplate>
<br>Items: <%# DataBinder.Eval(Container.DataItem,"ItemName")%></t></t></t><%# DataBinder.Eval(Container.DataItem, "Amount") %>
<br><%# DataBinder.Eval(Container.DataItem, "ItemDescription") %></br>
</ItemTemplate>
</asp:Repeater>
<asp:SqlDataSource ID="DataSourceMember" runat="server" ConnectionString="server=myComp;uid=sa;pwd=sa;database=ItemCat" SelectCommand="SELECT * FROM items where catID = '<%# DataBinder.Eval(Container.DataItem,"ID") %>'" \>
</ItemTemplate>
<separatortemplate>
<br />
<br />
<br />
</separatortemplate>
</asp:Repeater>
erros is :
Parser Error

Source Error:

Now we finally get to the issue, "Parser Error Message: The server tag is not well formed". You could have saved a few steps and gave this information at the beginning.
This is not the best way to accomplish this. You understand you are going to create a new SqlDatasource for each item in the parent list? Handle the ItemDataBound event of the parent repeater and assign the datasource, perferably from a cached source.

itemDataBound event is like this right:
void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
RepeaterItem item = e.Item;
if ((item.ItemType == ListItemType.Item) ||
(item.ItemType == ListItemType.AlternatingItem))
{
Repeater3 = e.Item.FindControl("Repeater3");
DataRowView drv = (DataRowView)item.DataItem;
Repeater3.DataSource = drv.CreateChildView("category_item");
Repeater3.DataBind();
}
}
but if i do like this, it give error as below:
Repeater3 doesn't exits..
while ascx.cs code is
<asp:Repeater runat="server" id="Repeater1">
<HeaderTemplate>items<br /><br /></HeaderTemplate>
<ItemTemplate>
<b><%# DataBinder.Eval(Container.DataItem, "catagoryname") %></t>
<br><%# DataBinder.Eval(Container.DataItem, "catagorydescription") %>
<asp:Repeater ID="Repeater3" runat="server">
<ItemTemplate>
<br>Items: <%# DataBinder.Eval(Container.DataItem,"ItemName")%></t></t></t><%# DataBinder.Eval(Container.DataItem, "Amount") %>
<br><%# DataBinder.Eval(Container.DataItem, "ItemDescription") %></br>
</ItemTemplate>
</asp:Repeater>
</ItemTemplate>
<separatortemplate>
<br />
<br />
<br />
</separatortemplate>
</asp:Repeater>

Repeater3 = e.Item.FindControl("Repeater3");
Of course it doesn't exist, what type is Repeater3? All you have is a name. You also understand FindControl needs to be cast to something useful?
