I have a datagrid that contains an HtmlInputHidden, something like:
<asp:datagrid id="dgCurrency" runat="server" CssClass="grid" AllowPaging="False" CellPadding="0"<br />
GridLines="Vertical" AutoGenerateColumns="False" ShowFooter="false" ><br />
<Columns> <br />
<asp:TemplateColumn HeaderText="ISO kode" HeaderStyle-HorizontalAlign="Left" ItemStyle-Width="150px"><br />
<ItemStyle HorizontalAlign="Left" VerticalAlign="Top"></ItemStyle><br />
<ItemTemplate><br />
<asp:Label id="lblISOCode" runat="server" CssClass="tbStyle1"><br />
<%#DataBinder.Eval(Container.DataItem, "strISOCode").ToString()%> <br />
</asp:Label><br />
<input type="hidden" runat="server" id="inCurrencyID" value='<%#DataBinder.Eval(Container.DataItem, "lngCurrencyID").ToString()%>' /> <br />
</ItemTemplate><br />
</asp:TemplateColumn><br />
...
Where the inCurrencyID is my HtmlInputHidden.
At the first time my page loads, I add a DataView to the dgCurrency datasource.
When I push a button the first time, the inCurrencyID has it's value, as in:
foreach (DataGridItem dgi in dgCurrency.Items)<br />
{<br />
inCurrencyID = (HtmlInputHidden)dgi.FindControl("inCurrencyID");<br />
<br />
int lngCurrencyID = int.Parse(inCurrencyID.Value);<br />
...
After this I don't databind the dgCurrency to a new datasource, I just leave it as it is.
Now the next time I push the same button, it has now lost it's value????
The same goes for the label lblISOCode.
The strange thing is that I also have an TextBox in the DataGrid, and that control stil have it's Text.
Dose anyone know why, or is there another hidden fild that I can use that dosen't lose it's value on a PostBack without a databind()?
Thanks

Possibly enableviewstate flag needs to be set to true.
You are using a standard html input item, rather than a dotnet control. This is ok since you set the runat server attribute. You may also want to set the enableviewstate="true" attribute as well. Not sure if this solves it, but worth a try.
An alternative would be to use an 'asp:label' tag and set it's visibility to false. This gives you a fully qualified dotnet control, yet is not displayed to the user.

i am using the followig code to display the message box using the code behind.
Response.Write("<script>alert('Hi');</script>");
The problem is , using this code , the background color of the same window gets white.
If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

its bcose, its a windows modal dialog message box. If u want Other, you should create a custom message box with div tag.

provide an example please.

I have a iTextObject control in the crystal reports, which is similar to the lable control in the aspx page.
can i hide the itextobject type control in the crystal report at run time.
If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

Sure, create a variable object for that Itextbox in the code and make tat invisible.
hope works

|

how should i find this control?

Thanks for the reply..
You are in the retriving phase. I am asking how to add a server control to the header ?
|
|
|
|
|
You can place the Image button in the header template also same way as row databound event gets fired for the headers and footers also.

Hi Dana,
I assume you have already added the ImageButton to the GridView. And here is how you do the rest.
The GridView's RowCommand event will fire when you click on that ImageButton in the GridView. That is in your code imgSortAssendingbyId.
(This command basically fires for any button’s click event, in the GridView).
Example:-
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
Response.Write("You Clicked the Button");
}
Thx,
Gayani

hi all,
i have a httphandler that returns an image when i send it text (and other parameters). The trouble is i have a need to send the string 'news + events', but the '+' is not being output at all.
code in page
_HeadingTextImage.ImageUrl = "textimage.ashx?text=" + Server.UrlEncode("news+events");
code in httphandler
string qText = (query["text"] == null) ? UsageText : context.Server.UrlDecode(query["text"]);
qText always = "news events" when i step into it.
can anyone tell me how to do this please?
thanks,
Maurice

hello,
thanks for the reply. that page encodes news+events as news%2Bevents which is what i get as input to the handler in the raw url (Request.QueryString)
but when i do Request.QueryString["qText"]; it return "news events", replacing the %2B with a space.
thanks,
Maurice

thank you i have resolved the issue.
if i urldecode the query in the handler it doesnt work, but if i urlencode the url in the page then just process it in the handler without urldecode'ing it, then it works fine.
regards,
maurice.

currently i m using asp.net with c# (.net 2005, 2.0 framework) and sql server 2000.
i want to store a sql query into a field in database... how to do it?
execute the below statement, and how to store it?
INSERT INTO tbl_templates_rsamonitoring(Template_Name,query,insert_date) values('sample','select tbl_rsa.rsa_level4 as \"BU - Level 4\",tbl_rsa.rsa_level5 as \"BU - Level 5\",tbl_rsa.rsa_sbu as \"BU - Level 3\",tbl_rsa.rsa_category as \"BU - Level 1\",tbl_rsa.rsa_level8 as \"BU - Level 8\",REPLACE(CONVERT(VARCHAR,tbl_rsa.rsa_ctrlculture, 106), ' ', '-') as \"Control Culture\" from tbl_rsa where rsa_mode=1','5/15/2008 3:53:47 PM')
that is...
template_name = sample
query='select tbl_rsa.rsa_level4 as \"BU - Level 4\",tbl_rsa.rsa_level5 as \"BU - Level 5\",tbl_rsa.rsa_sbu as \"BU - Level 3\",tbl_rsa.rsa_category as \"BU - Level 1\",tbl_rsa.rsa_level8 as \"BU - Level 8\",REPLACE(CONVERT(VARCHAR,tbl_rsa.rsa_ctrlculture, 106), ' ', '-') as \"Control Culture\" from tbl_rsa where rsa_mode=1

It's a string, so store it in an nvarchar column. Did I miss something ?
