Hi,
Below code solves your problem.
<script language='javascript'>
function newtest()
{
if(document.getElementById("CheckBox1").checked == true)
document.getElementById("DropDownList1").disabled = true;
else
document.getElementById("DropDownList1").disabled = false;
}
</script>
Add the below code inside checkbox tag..
OnClick="newtest()" 'removed' text has to be changed to 'onclick'
Hope this helps you...

I downloaded MembershipEditorAtlas1.zip and used asp.net configuration to configure it.
But it keeps giving the error
The type specified in the TypeName property of ObjectDataSource 'ObjectDataSourceMembershipUser' could not be found.
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.

There are a couple things which you might want to check:
+ Where is the type specified in the TypeName property defined? (In the App_Code folder or in a seperate assembly)
+ Check the assembly reference if any.
+ Check if the type name in the TypeName property is qualified or not?

Gave up on earlier post of using imageButtons and command arguements, but can't get the following to work either. When trying to delete a row, and using the SELECT rows, I get an error of the selected index out of range even though I'm asking it to select the record in the dataset based on a primary key field (the rows commented out). When using the FIND rows, it stops on the row.delete() line with an error of "Object reference not set to an instance of an object." Really frustrated and would appreciate some help.

I have two pages A and B.
ON page A, I have three drop down boxes ( month , year, and unit_abbr and they have cascading and Auto post backs) and click button to run a report. What I am trying to do is keeping selected drop down list values after the postbacks. The problem right now is when I come back to page A after I browse page B , the selected values in dropdown boxes are set back to the default ( in my case most recent month, year, unit_num). How can I keep the selected values inside of dropdown lists while I am browsing around different pages? If I select month = 1 year 2006 unit_abbr = D11 to run the report on page A, then go to the different page to browse around different report and when I come back to Page A, the selected parameters in those drop down lists should be set to month = 1 year 2006 unit_abbr = D11
Here is my code using session variable:
<asp:label id="Label4" runat="server" text="Select Year:" forecolor="Black" font-bold="True" font-names="Arial" font-size="8pt">
<asp:dropdownlist id="DropDownList2" runat="server" datasourceid="SqlDataSource3" datatextfield="year" datavaluefield="year" font-names="Tahoma" font-size="8pt" autopostback="True" onselectedindexchanged="DropDownList2_SelectedIndexChanged1">
<asp:label id="AccountStatus" runat="server" font-size="16pt" visible="False" width="87px">
<asp:label id="Label5" runat="server" text="Select Month:" forecolor="Black" font-bold="True" font-names="Arial" font-size="8pt">
<asp:dropdownlist id="DropDownList1" runat="server" datasourceid="SqlDataSource2" datatextfield="month" datavaluefield="month" font-names="Tahoma" font-size="8pt" onselectedindexchanged="DropDownList1_SelectedIndexChanged" autopostback="True">
<asp:label id="Label7" runat="server" text="Select Region:" forecolor="Black" font-bold="True" font-names="Arial" font-size="8pt">
<asp:dropdownlist id="DropDownList4" runat="server" autopostback="True" datasourceid="SqlDataSource6" datatextfield="region_name" datavaluefield="Region_num" font-names="Tahoma" font-size="8pt" onselectedindexchanged="DropDownList4_SelectedIndexChanged">
--Here is code behind
public
partial class Dashboard : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack && ((this.Session["MMselectedvalue"] != null) && (this.Session["YYselectedvalue"] != null)
if (!Page.IsPostBack && ((this.Session["MMselectedvalue"] != null) && (this.Session["YYselectedvalue"] != null) && (this.Session["Unitselectedvalue"]) != null) && (this.Session["Regionselectedvalue"] != null))
{
this.DropDownList1.SelectedIndex = Convert.ToInt32(this.Session["MMselectedvalue"]);
this.DropDownList2.SelectedIndex = Convert.ToInt32(this.Session["YYselectedvalue"]);
this.DropDownList3.SelectedIndex = Convert.ToInt32(this.Session["Unitselectedvalue"]);
this.DropDownList4.SelectedIndex = Convert.ToInt32(this.Session["Regionselectedvalue"]);
GridView4.DataBind();
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
this.Session["MMselectedvalue"] = this.DropDownList1.SelectedIndex;
}
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
this.Session["YYselectedvalue"] = this.DropDownList2.SelectedIndex;
}
protected void DropDownList3_SelectedIndexChanged(object sender, EventArgs e)
{
this.Session["Unitselectedvalue"] = this.DropDownList3.SelectedIndex;
protected void DropDownList4_SelectedIndexChanged(object sender, EventArgs e)
{
this.Session["Regionselectedvalue"] = this.DropDownList4.SelectedIndex;
But, the problem is the data controls of drop downboxe ( sql datasource) are overwriting the session varialbles, so it set back to the default value...
How can I keep the session variables after the data binding ( sql datasource for drop downboxes)? ,and How can I ditermine whether it's just a postback ( changing selected values on the same page) or the user is actually changing the page( navigate different pages and come back to the same page).?

In the selectedIndexChange event handler add the selected index to a session.
Then in page_load you check for a postback (you do nothing). If there is no postback you check the session if it contains those stored indexes and if it does you fill the drop downs with data and then select the one that is in the session.

You may also need to set the selected indexes from session after the ddls are databound.
|
|
|
|

How can I do that? Can you provide me some code examples?

Thanks, I think I almost figured it out.. except the dropdownlist3 is still set back to the default value ( doesn't remember previous selected value). Is it because the dropdownbox3 is populated by the drop down box4 ( cascading dropdown box)? How can I work around this?
--Here is the code for dropdownbox3
<asp:dropdownlist id="DropDownList3" runat="server" datasourceid="SqlDataSource4" datatextfield="unitname_abbr" datavaluefield="unit_abbr" width="352px" font-names="Tahoma" font-size="8pt" onselectedindexchanged="DropDownList3_SelectedIndexChanged" autopostback="True">
<asp:sqldatasource id="SqlDataSource4" runat="server" connectionstring="<%$ ConnectionStrings:Finance_AppsConnectionString %>" selectcommand="
select distinct(unit_name) as unit_name,unit_abbr
, ( convert(varchar(5), unit_abbr) + ' - ' + convert(varchar(50), unit_name))as unitname_abbr
from revenue_aggregate
where region_num = @region_num
group by unit_name, unit_abbr
order by unit_abbr">
<selectparameters>
<asp:controlparameter controlid="DropDownList4" name="region_num" propertyname="SelectedValue">
--------------------------------------------------Updted code
if (!Page.IsPostBack)
{
try
{
this.DropDownList1.SelectedIndex = Convert.ToInt32(this.Session["MMselectedvalue"]);
this.DropDownList2.SelectedIndex = Convert.ToInt32(this.Session["YYselectedvalue"]);
this.DropDownList3.SelectedIndex = Convert.ToInt32(this.Session["Unitselectedvalue"]);
this.DropDownList4.SelectedIndex = Convert.ToInt32(this.Session["Regionselectedvalue"]);
}
catch
{
}
}
else

Hi.
I have DataGrid that has 11 columns. Some of the columns are white and some are gray. How can I change row color onmouseover and when put the original color back? I've tried to use in the
ItemDataBound the following
e.Item.Attributes.Add("onmouseover", "changeMouseOverandOut(this, false)")
and in the JavaScript
var lastColorUsed;
function changeMouseOverandOut(row, highlight){
if(!highlight) {
lastColorUsed = row.style.backgroundColor;
row.style.backgroundColor = '#FFFF66';
}
else
row.style.backgroundColor = lastColorUsed;
}
It does work but only for white background. My gray background color doesn't change. Setting background color from ItemDataBound gives the same result so that's why I used JavaScript function (it is nice to try new things).
Please hlep.

Hi AlexFromTo
Here is a codesample that shows how you can get the desired result for a cell, you can probably modify the code to change a row instead.

Hello,
I am creating a web site using ASP.Net using C#. I want customers to buy products from the website. What is the best and most secure way to use different payment methods. The website will need to be able to use credit cards, and another payment method, e.g. paypay. What is the best way to implement these into a ASP.Net website?
Thanks in advance,
Steve
