I have a comboBox within a grid. Basically to get it I have to use findcontrol. I am thinking of another option however. Within the init method I was planning on getting the value and storing it to a private static field:
private static RadComboBox theComboBox
Is it unwise to be storing a relatively complex object like this in a static field?
I have the following items bound to my combobox:
Value: 1, Text: SNS
Value: 2, Text: ING
Value: 3, Text: ING
Choosing value 1 results in a SelectedValue of 1
Choosing value 2 results in a SelectedValue of 2
Choosing value 3 results in a SelectedValue of 2
does the combobox has as a disadvantage that the Text has to be unique?
I'm try to add a combobox to my form which i have done and populate it with the infomation i need but i want to stop the user from being able to edit the first 5 character in the textbox part of the combo box( 1 is this possible 2 am i going about it in the right way).
I have 3 columns fro a db to enter ips ie 123.456.7.89 at the start if each number i want (SE1)(SE2)(SE3) which i can do at the momment . So I get in the combobox list 3 items with (SE1)123.456.7.89 OR just (SE1) depending of i a result is returned from the DB. However i don't want the user to be able to edit out the (SE?) part of the sting in the textbox. When editing i've tried used the text change event to try and capture the change and make sure the string.length > 5 , but the event does not fire also when i leave the combobox it it adds to the combox list. If I refersh it goes back to how it should be with only the 3 items.
I have a problem with CascadingDropDown... I have two related comboboxes, where the second is a slave of the first (e.g. country the first, cities the second). What I want is that if I select one country from combobox 1 then the second must be "filtered" by that selection (it should display all the cities inside the selected country, and the actual CascadingDropDown implementation is OK), but if I leave the combobox 1 in the default option (e.g. "Please select a country") I want the second to display all the cities I have in the database. The problem is that when selecting default option for combobox 1 the second combobox is disabled and a postback to my webservice never occurs.

it binding correctly(datasource dynamically binded) and it raises event too while changing index but it is not raising event when we manually clearing the combobox text..if currently combobox having text "ASP" then i manually select that entire text and using del key i am deleting but it is not raising event for me.. when i change index it automatically raising event...i need to raise event while combobox is empty...
How do you refresh a combo box from clicking on something from another Combobox (using Visual Basic).
I don't want to use a button for this as i know it works that way by using .Databind() on the other combobox.
In access it is so easy by using the click event on a combo box but visual studio does not seem to use it.
i have one grid and one button when i click on that button then it expand and showing another grid under the row of parent grid how to do that.
View 2 RepliesI have a name textbox, label, usercontrol, submit button in my page inside a master page. when the button is clicked iam using the label to show the user "Please enter name".

View 2 RepliesI created checkbox in a gridview. I hope to retain the checkbox value after postback.

Platform: ASP.Net 2.0 I have multiple checkboxlist controls on a webpage. Along with that i have the same number of buttons on that page. Initially all the checkboxlist controls are hidden. When user clicks on a button, corresponding checkboxlist controls gets visible making others hidden and allows user to select the options.
On postback, if user clicks on the same button again, the corresponding checkboxlist gets visible but the item selection is not retained. However, this happens only in IE. This works fine in FireFox. I am using JQuery to toggle the visibility of checkboxlist.I guess the problem is because i am toggling the visibility of checkboxlist which IE doesnt seem to like. What is the solution to this problem?
I'm using the asp.net PreviousPage functionality and cross-page postback. The problem i'm running into is that if I have any postbacks on my page, the PreviousPage information seems to be lost. I don't want to put it in ViewState because that will be quite large. I've thought about Session, but I don't want the data to persist after i've moved on to another page, and I really don't like the idea of putting code in all my other pages to delete old session variables.
View 1 RepliesI have created .msi and .exe installer for one website. I now want to install this on Windows server 2003 with IIS 6.

View 1 RepliesI'm trying to retain "visible" property of a control using view state in the following way
public bool showstatusbox {
get { return Convert.ToBoolean(ViewState["statusbox"]); }
set { ViewState["statusbox"] = value; }

Is there anything I should do other than this to retain value. Because, though I store the value in view state, on postback, its becoming null.
I'm trying to use jQuery to disable an ASP.Net button control and set the flag in a hidden input field. However, the value does not seem to be staying, for some reason. I am new to jQuery, so I'm having a hard time trouble-shooting this:

I have a simple ASP.NET page where after the initial page load the user enters a username and a password to two text boxes. Note that I can not use the built-in login control in ASP.NET, as my purpose of using this username and password is slightly different.Now, I want the user to enter the said two values only once. Afterwards, using those two values I perform several tasks. Now here's the tricky part; since I set the TextMode property of the password text box to 'password', every time a button click occurs it clears the password field, and since every button click event triggers a page load as well, I lose the password data. But I do not want the user to keep entering the password every time he has to click a button.How can I retain the username and password in my code? If this were a normal .NET Windows Application, I would use a global variable and assign the value the first time and I would have it available to me throughout the life cycle of my program. But how can I do it here?

I am trying to set the checked status of a radiobutton in code, but it doesnt retain after the code-behind execution completes. It still shows the design time checked status.
View 3 RepliesI have a very simple user control with 5 radio buttons on it, and 3 properties (ID, RatingSetID, and Rating). On the initial load of the page they are on, the code acquires data and places the data into the 3 properties. However, when the submit button is clicked the page reloads and the 3 properties get reset to 0, they are in the !IsPostBack as well.
View 2 RepliesI am reading a MSWord Document (docx) in my C# code.Then I get the InnerText of the word document into a string which goes into the Body section of an email.The problem is that when I do something like the following:

Everything comes in one line and all the formatting is lost.
I have a Listbox getting populated when the page loads itself and also in postbacks. Some items are already selected in that listbox even when the page loads or postbacks. I have to select one or more items in that textbox in addition to the selected one.
Till this point, it works perfectly, but the problem is that when i click an "update" button to save the newly added items, then also the page postbacks and so the list box get populated again. This will loose the newly selected items and none of the newly selected items will be saved.
So what should i do in order not to loose the newly selected items when i click the "update" button.
Note:- I need to populate the listbox on postbacks also. So the population of that listbox on postbacks cannot be discarded.
I'm using a hidden field to store a value in an asp.net page. Basically I set the value of the hidden field whenever a value on the form is changed i.e. first name, date etc. The field is on a webform that has a master page and is in the content section:
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<asp:HiddenField ID="hdnDirtyFlag" runat="server" Value='false' />
I change the value of the field in javascript by calling a function whenever an onchange event fires in other controls on the web form:
<asp:TextBox CssClass="niceInput" ID="tbFirstName" runat="server" MaxLength="40" Width="150" onchange='SetHiddenVariable();'></asp:TextBox>
<script type="text/javascript">
function SetHiddenVariable() {
// Set the value of the hidden variable so we know a field has been updated
var hiddenControl = '<%= hdnDirtyFlag.ClientID %>';
document.getElementById(hiddenControl).value = 'true';
}
</script>
So far so good. When the page loads the hidden field value is 'false', and if I don't change any values on the webform it remains false. Whenever I do change another control the javascript function gets called and the hidden field value gets updated to 'true'. Again this is all fine.
After I submit the form and update the database, I set the hidden field value back to 'false' in the code behind:
hdnDirtyFlag.Value = "false";
But when I click another button and do a postback, the hidden field value is still at 'true'.
Can anyone explain why this is? I stepped through the code behind and immediately after changing the value I can see the value is 'false'. There is an asp:UpdatePanel on the page but the hidden field is not part of this panel.
EDIT:
This is the code I use to check the value of the field in code behind in the second postback, after it has been set to false in the last step of the first postback. The value remains at true for some reason in the second postback, after it has been set to true in javascript on the client side then set back to false in code behind as shown above:
if (hdnDirtyFlag.Value == "true")
{
UpdateSecurityObject();
}
I need to make a dropdownlist webusercontrol that shows a list of years. The control needs to be flexible enough so that I can tell it show X number of years before and after this year. So if I said show 2 years before after this year the dropdownlist would show 2008, 2009, 2010, 2011 & 2012. In the past I've stored the "X years" for later use by exposing a property and then storing the value in a hidden field. EG:
[Code]....
I want to store the "X years" values that I send to the control the first time - so not a value that I send in a postback. Is there a better way than using a hidden field?
I have a ASP DropDownList that gets populated on the Page_Load event, after i select an item and hit a button the selected item gets cleared and the first item in the DropDownList gets selected. (The DropDownList is only populated when the page is not postback)
if (!IsPostBack)
{
List<Country> lCountries = new List<Country>();
List<CompanySchedule> lCompanySchedules = new List<CompanySchedule>();
this.Load_Countries(lCountries);
[code]...
I have some fields based on which select criteria is decided. I got some dropdowns there as well. I'm repopulating dropdown values again with search results in post method and verified that they are receiving selected item but still after load it vanishes.
View 2 RepliesI have a project in VB.NET which is working fine which essentially has a Datagrid that has a TemplateColumn included which is a column of Checkboxes. The code to declare the datagrid is here...
<asp:datagrid id="dgDates" OnItemCommand="gridEventHandler" BorderColor="Black" BorderWidth="1px"
CellPadding="3" runat="server" AutoGenerateColumns="False" HorizontalAlign="Left" AllowSorting="True"
OnSortCommand="SortData" OnItemDataBound="gridItemDataBound">
<HeaderStyle Font-Underline="True" Font-Bold="True" HorizontalAlign="Center" ForeColor="Black"
BackColor="#D4D0C8"></HeaderStyle>
<Columns>
<asp:BoundColumn DataField="strParameterName" SortExpression="strParameterName" HeaderText="Parameter Name"></asp:BoundColumn>
<asp:BoundColumn DataField="dtParameterValue" SortExpression="dtParameterValue" HeaderText="Parameter Value"></asp:BoundColumn>
<asp:TemplateColumn HeaderText="Constant" SortExpression="blnStatic" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:CheckBox ID="cbStaticRolling" Checked="False" Runat="server" AutoPostBack="true"></asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
as you can see the Checkbox has Autopostback="true" but there are other things on the page which produce postbacks as well.
My Page_load has this in it, being called on every load of the page, postbacks included...
Dim strGUID As String
strGUID = Session("strGUID")
dgDates.DataSource = SqlHelper.ExecuteDataset(ConfigurationManager.AppSettings(Web. [Global].CfgKeyConnStringADMIN), "dbo.spRptGetSchedulingDates", strGUID)
dgDates.DataBind()
intNumberOfDates = dgDates.Items().Count
as well my code behind has the following code for the gridItemDataBound
Protected Sub gridItemDataBound(ByVal sender As System.Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs)
'hide the intRptSchedulingDatesID for each row in the checkbox's content style variable
If (e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem) Then
CType(e.Item.FindControl("cbStaticRolling"), CheckBox).Style("Content") = CType(e.Item.DataItem, System.Data.DataRowView).Item("intRptSchedulingDatesID")
End If
End Sub
everything you see sbove is working perfectly fine...in the sense that when I click one of the checkboxes, the page_load fires, the gridItemDataBound fires on DataBind() and when all is done, the checkbox retains the value that the user clicked the checkbox.
With all this exact same code converted to C#....the events all fire in the same order, but the checkbox selected value always clears...any thoughts??
