The function below is to check and uncheck the entire Checkbox column, you need to do some changes to for ur requirment:
Call will be as follows:
<asp:CheckBox ID="CheckAll" Text="Check all" runat="server" onclick="return check_uncheck (this );" />
Function starts here:
function check_uncheck(Val)
{
var ValChecked = Val.checked;
var ValId = Val.id;
var frm = document.forms[0];
// Loop through all elements
for (i = 0; i < frm.length; i++)
{
// Look for Header Template's Checkbox
//As we have not other control other than checkbox we just check following statement
if (this != null)
{
if (ValId.indexOf('CheckAll') != - 1)
{
// Check if main checkbox is checked,
// then select or deselect datagrid checkboxes
if (ValChecked)
frm.elements[i].checked = true;
else
frm.elements[i].checked = false;
}
else if (ValId.indexOf('deleteRec') != - 1)
{
// Check if any of the checkboxes are not checked, and then uncheck top select all checkbox
if (frm.elements[i].checked == false)
frm.elements[1].checked = false;
}
} // if
} // for
}

Hi
I have created a user control which inherits from UserControl amd implements ITemplate. I am setting my datalist's item template to this external resource using Page.LoadControl. But when the datalist is bound to a datasource, I don't see the data displayed in the expected way. Only the last item in the datasource is displayed by the datalist for the item template colum.
Here is my class.
UserControl code behind
========================
<br />
public partial class StateListTemplate : System.Web.UI.UserControl, System.Web.UI.ITemplate<br />
{<br />
private bool _bDisplayStateName = false;<br />
<br />
public bool DisplayStateName<br />
{<br />
set {_bDisplayStateName = value;}<br />
get { return _bDisplayStateName;}<br />
}<br />
<br />
public void InstantiateIn(System.Web.UI.Control container)<br />
{<br />
container.Controls.Add(this);<br />
}<br />
....<br />
protected string GetStateDisplayString(string sStateCode, string sStateName)<br />
{<br />
if (DisplayStateName)<br />
return new System.Text.StringBuilder(sStateCode.Trim()).Append("-").Append(sStateName.Trim()).ToString();<br />
else<br />
return sStateCode;<br />
}<br />
<br />
User Control .ascx
==================
<br />
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="StateListTemplate.ascx.cs" Inherits="EtaxWeb.UserControls.StateListTemplate" %><br />
<asp:Label runat="server" Text="Test1"></asp:Label><br />
<%# GetStateDisplayString((string)DataBinder.Eval(((DataListItem)Container).DataItem, "Value"), (string)DataBinder.Eval(((DataListItem)Container).DataItem, "Text"))%><br />
Code where the datalist's itemtemplate is set to the above user control and datbound.
<br />
StateListTemplate stlist = (StateListTemplate)LoadControl("../UserControls/StateListTemplate.ascx");<br />
stlist.DisplayStateName = false;<br />
dlStates.ItemTemplate = stlist;<br />
dlStates.DataSource = states;<br />
dlStates.DataBind();<br />
I could have just used a class with ITemplate interface, but just wanted to see if this is possible as it would help to code the controls declaritively in the user control and add it to the container in the InstantiateIn method rather than having to declare eacha nd every control and adding it to the container.
Any Help is appreciated!

1>Is there any way i can remove the space between the outer border of the checkbox and the actual check box.
2>I have a fileupload control, how can i apply style to the browse button.

Is there some way the requests can be made to operate at the same time?
i have one button. everytime user clicks the button a call to database is made Asynchronously and the results are shown in the grid on completion. For every database result there is a new row in the grid. The problem is, every asynchronous call executes after the previous one is completed showing a behaviour of queues. However i need pure asynchronous tasks that is the results of less time consuming should appear first even if it was started at later. for more clarity here is code for both aspx and aspx.cs. before executing this code please make sure the connection string is ok for your machine. on execution click the button immidiately more than one times and see the start and end times.
Thanks in advance.
Regards,
Ishfaq Hussain

Hi All,
I need to use AJAX CascadingDropDown and AutoCompleteExtender together, i mean I have to combine these two controls but I am not getting how to do this.
My code is works fine if I use these two controls separately but when I combine these 2 controls, I dont get the proper result.
Please help me...
Thanks in advance...
|
|
|
|

AutoCompleteExtender Control is used for Textbox.It returns result of string on KeyChange event of TextBox. CascadingDropDown Control is used for multiple DropdownList.
I combine these 2 controls
Can U tell me How did u combine these two controls.?
Best regard
Pathan
---------------------------------------------------
|
|
|
|

Some what like this:
"
<code>
<ajaxToolkit:CascadingDropDown ID="CascadingDropDown4" runat="server" TargetControlID="ddlCompany"
ParentControlID="ddlSubIndustry" Category="Company" PromptText="Select Company"
ServicePath="AutoComplete.asmx" ServiceMethod="GetTicker" />
<asp:DropDownList ID="ddlCompany" runat="server" Width="222px"
OnSelectedIndexChanged="ddlCompany_SelectedIndexChanged">
</asp:DropDownList>
<asp:TextBox runat="server" ID="myTextBox" Width="234px" autocomplete="off" Style="font-size: 9pt"
CssClass="blue-text" Height="14px" />
<ajaxToolkit:AutoCompleteExtender runat="server" ID="autoComplete1" TargetControlID="myTextBox"
ServicePath="AutoComplete.asmx" ServiceMethod="GetCompletionList1" MinimumPrefixLength="0"
CompletionInterval="1000" EnableCaching="true" CompletionSetCount="12"
CompletionListElementID="ddlCompany" /> </code> "
|
|
|
|
|
What is CompletionListElementID in AutoCompleteExtender?.and Why did u use dropdownlist 'ddlCompany' in AutoCompleteExtender?
Can I see GetCompletionList1 Method?
Best Regard
Pathan
---------------------------------------------------
|
|
|
|

As I want to show it in list formate so I use this "CompletionListElementID"
and the code for GetCompletionList1 is below:
public string[] GetCompletionList1(string prefixText, int count)
{
conn.ConnectionString = cs.connectionDBcentral();// new SqlConnection("server='192.168.11.7'; user id='cd'; password='cd'; database='DbCentralData'");
DataTable dtReturn = new DataTable();
conn.Open();
SqlCommand cmd = new SqlCommand("SELECT Top 10 Ticker,coname FROM tbCompMaster where (Ticker like @searchterm or coname like @searchterm )ORDER BY coname ", conn);
SqlParameter param = new SqlParameter();
param.ParameterName = "@searchterm";
prefixText.Trim().Replace("'", "''");
prefixText += "%";
param.Value = prefixText;
cmd.Parameters.Add(param);
SqlDataAdapter adpt = new SqlDataAdapter(cmd);
adpt.Fill(dtReturn);
//Random random = new Random();
List<string> items = new List<string>(count);
for (int i = 0; i < dtReturn.Rows.Count; i++)
{
string c1 = (string)dtReturn.Rows[i]["Ticker"];
string c2 = "-";
string c3 = (string)dtReturn.Rows[i]["coname"];
items.Add(c1 + c2 + c3);
}
conn.Close();
return items.ToArray();
}
Actually I have return another fuunction which fills Company Combo and it is:
public CascadingDropDownNameValue[] GetTicker(string knownCategoryValues, string category)
{
string[] SectorValues = knownCategoryValues.Split(';');
string[] cou = SectorValues[0].Split(':');
Session["Country"] = cou[1];
string[] sec = SectorValues[1].Split(':');
string[] subindustry = SectorValues[2].Split(':');
Session["SubindustryID"] = subindustry[1];
string key = "Category" + subindustry[1];
DataSet ds = (DataSet)HttpContext.Current.Cache[key];
ds = new DataSet();
SqlConnection myConnection = new SqlConnection();
if (ds != null)
{
switch (Convert.ToInt16(Session["Country"]))
{
case 1:
conn.ConnectionString = cs.connectionUS();
break;
case 2:
conn.ConnectionString = cs.connectionUK();
break;
case 3:
conn.ConnectionString = cs.connectionJP();
break;
default:
conn.ConnectionString = cs.connectionUS();
break;
}
conn.Open();
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
string strcomp = sec[1] + "______";
cmd.CommandText = " SELECT Top 10 Ticker,coname FROM tbCompMaster where GICSCode =" + Session["SectorID"] + " or GICSCode=" + Session["SubindustryID"] + " ORDER BY coname";
SqlDataAdapter adpt = new SqlDataAdapter(cmd);
adpt.Fill(ds);
DateTime t =DateTime.Now.AddHours(24);
HttpContext.Current.Cache.Insert(key, ds);
conn.Close();
}
else
{
ds = (DataSet)HttpContext.Current.Cache[key];
}
List<ajaxcontroltoolkit.cascadingdropdownnamevalue> values = new List<ajaxcontroltoolkit.cascadingdropdownnamevalue>();
foreach (DataRow row in ds.Tables[0].Rows)
{
values.Add(new AjaxControlToolkit.CascadingDropDownNameValue(row["coname"].ToString(), row["Ticker"].ToString()));
}
return values.ToArray();
}
But I am not getting how to combine these two function so that it works fine.
Please help me...
Thanks again...

I have designed one form where there is a datagrid having included all the generation operations like edit, delete data.I have used sql server 2005 to bring data to the datagrid.Now when i dont include the master page in this form and try to run this form alone,it gives flawless output.But when i include the master page in this form and try to run this form, it gives error like:
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machinekey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
Anybody can tell me why such error generally occurs and how to debug this ???Where to give this machine key ??

For my website i'm using the login controls from the toolbox of visual web developer.
When a staff gets validated he/she gets directed to the staff page instantly
When a Manager gets validate he/she gets directed to the manager page instantly.
Anyone has any clue as to how to do this. ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)
I hate using a code based login.

just check the credentials Put one Home page or any page after login in that check the type of user from database or where you are storing then have if or switch statement check the credentials then just transfer to that page
Thanks and Regards
