Set ListItem Value To Constant For RadioButtonList In ASPX
Sep 23, 2010
I must be doing something wrong here but I can't find an easy way to get this to work. Imagine the following code:
<asp:RadioButtonList ID="MyRadioButtonList" runat="server">
<asp:ListItem Value="<%= CompanyName.SystemName.Constants.PaymentFrequency.FREQUENT.ToString() %>" Text="Yes" Selected="True"></asp:ListItem>
<asp:ListItem Value="<%= CompanyName.SystemName.Constants.PaymentFrequency.ONCE.ToString() %>" Text="No, Just do this once"></asp:ListItem>
</asp:RadioButtonList>
But it doesn't compile the statement before it renders the page. So if I get the selected value of this radiobuttonlist it contains something like "<%= Compan... %>" instead of what my constant defines.
On the first ListItem I need to have a label that displays some text from the code behind of the page. Logically it seems to me like I would be able to do something like this: 100% Obviously this does not work because I am getting an error: The 'Text' property of 'asp:ListItem' does not allow child objects.
I have a RadioButtonList with three ListItems, like this:
[Code]....
TrueRuleCondition, FalseRuleCondition, and CustomRuleCondition are protected constants in the code-behind file that I want to use as the values for my listitems. Unfortunately, the values get treated as literal values instead of having the values of the variables inserted. Does anyone know of a way to do this or why this doesn't work as I expect it to?
I am using jquery and c# to dynamically set a radiobuttonlist listitem to selected. I want to create a reset-type button to reset the radiobuttonlist selected item back to the first item in the list. jQuery/jsTree function currently reseting textbox and hidden field:
$('#ContentPlaceHolder1_hfNodeID').val(''); $('.txtPage').val(''); $('.rblContentTypesGetAll').val(); $('.contentPageForm').show(), .rblContentTypesGetAll is the radiobuttonlist i want to reset (or select the top most listitem). HTML of the form: <asp:Panel ID="PagesForm" CssClass="contentPageForm" runat="server"> <asp:HiddenField ID="hfNodeID" runat="server" Value="" /> <table> <tr> <td>Page</td> <td><asp:TextBox ID="txtPage" CssClass="txtPage" runat="server" /><span class="validate">*</span><br /> <asp:RequiredFieldValidator ID="rfvPage" runat="server" CssClass="validate" ControlToValidate="txtPage" Display="Dynamic" ErrorMessage="Page Name Required" ValidationGroup="page" /></td> </tr> <tr> <td>Content Type</td> <td> <asp:RadioButtonList id="rblContentTypesGetAll" CssClass="rblContentTypesGetAll" OnLoad="rblContentTypesGetAll_Load" runat="server" > </asp:RadioButtonList> </td> </tr> <tr> <td> <asp:Button ID="Submit" runat="server" OnClick="PageSubmit_Click" Text="Save" ValidationGroup="page" /> <asp:Button ID="Cancel" runat="server" OnClick="Cancel_Click" Text="Cancel" /> </td> </tr> </table> </asp:Panel>
I have 2 radiobuttonlist in a web forms, each contains of 4 ListItem. So there are 8 ListItems in total. It is initialised such that none of the ListItems is selected. I want to validate that at least one of the ListItems is selected when submit button is pressed. How to do it? i.e. at least 1 ListItem is selected, either from radiobuttonlist1 or radiobuttonlist2.

Is it possible to add the ListItem values in the code-behind within a for loop? If so, what is it? Here is my current code:
rblContentTypesGetAll.Items.Clear(); for (int i = 0; i < dt.Rows.Count; i++) { rblContentTypesGetAll.Items.Add(dt.Rows[i]["contentType"].ToString()); }
I have two radiobuttons in radiobuttonlist and based on selection, i am enabling and disabling the text box. First time i used date radiobutton and i took date in corresponding textbox and i saved it into database and then when i came back on same page i saw the date radiobutton is checked has proper value then i clicked on another radiobutton and this time page is postback and clear my all the data which was in my other controls(I have 5-6 text boxed on my page). I dont know why?, It supposed to select my other radiobutton and enable the corresponding text box
[Code]....
if (!Page.IsPostBack) { if (gvCredentialTypes.SelectedIndex >= 0) { CredentialType credType = CredentialType.FindCredentialType(gvCredentialTypes.SelectedValue.ToString()); if (!String.IsNullOrEmpty(credType.CredentialTypeName)) //If exists, load data { String expDays = credType.ExpirationLength.ToString(); DateTime expDate = Convert.ToDateTime(credType.ExpirationDate); // Assign the value to the controls LoadExpirationDaysDateValue(expDays, expDate); } } }
private void LoadExpirationDaysDateValue(String expDays, DateTime expDate) { // Determines whether value for Days or Date is present Boolean IsDays = false; // Check if days value is present if (String.IsNullOrEmpty(expDays) || expDays.Equals("0")) { txtExpirationDays.Text = String.Empty; } else { txtExpirationDays.Text = expDays; IsDays = true; } if (expDate.ToShortDateString().Equals ("1/1/0001")) { txtExpirationDate.Text = String.Empty; } else { txtExpirationDate.Text = expDate.ToShortDateString(); IsDays = false; } // Set the radio button value based on whether Date or Days value is present if (IsDays) { // Get ref to the 1st radio item ListItem liExpirationInDays = rbExpiration.Items.FindByValue("rbExpirationInDays"); if (liExpirationInDays != null) { liExpirationInDays.Selected = true; rbExpiration.Items.FindByValue("rbExpirationDate").Selected = false; txtExpirationDate.Text = string.Empty; txtExpirationDays.Text = expDays; // Enable or disable the controls based on the radio button selection txtExpirationDays.Enabled = true; RequiredFieldValidator1.Enabled = true; RangeValidator1.Enabled = true; txtExpirationDate.Enabled = false; RegularExpressionValidator1.Enabled = false; CalendarExtender2.Enabled = false; //compDateValidator.Enabled = false; RequiredFieldValidator2.Enabled = false; } } else { // Get ref to the 2nd radio item ListItem liExpirationDate = rbExpiration.Items.FindByValue("rbExpirationDate"); if (liExpirationDate != null) { liExpirationDate.Selected = true; rbExpiration.Items.FindByValue("rbExpirationInDays").Selected = false; txtExpirationDays.Text = string.Empty; txtExpirationDate.Text = expDate.ToShortDateString(); // Enable or disable the controls based on the radio button selection txtExpirationDate.Enabled = true; RegularExpressionValidator1.Enabled = true; RequiredFieldValidator2.Enabled = true; CalendarExtender2.Enabled = true; //compDateValidator.Enabled = true; txtExpirationDays.Enabled = false; RequiredFieldValidator1.Enabled = false; RangeValidator1.Enabled = false; } } }
I have a radiobuttonlist inside a datalist itemtemplate and i need to bind the radiobuttonlist dynamically from database I have tried to bind it inside itemdatabound event of datalist but it the result is always duplicated according to the fields in teh database.
for more information:
the database has two columns one for questions and the other is for choices , for the first question with id lets say 1 there are 4 choices, when the radiobutton is binded the result appears to be 4 times duplicated ?
( header is a custom control -- it simply adds some css by default and position ). In such case quotes marks have higher priority and entire text is sucked as-is, in effect I get header with text
<%= Foo.Bar %>
So, my question is -- what is the syntax to get the value of C# constant, no matter what (IOW -- with highest priority)? Edits:
I have a function that calculates the exchange rate between two currencies. The inputs are constants:
[Code]....
I have currency codes in my database listed as "EUR", "USD" etc. that I want to use in the function. Unfortunately the function requires a constant value like CurrencyExchangeRate.Currency.EUR instead of a string value called "EUR" How can I turn the value from the database into a usable value for the function?
I know it must be very simple but I cannot figure it out.
How would one create a website that would look the same at any resolution? I've heard of making so it will fit for a 800x600 screen but then that just screws everyone that has a higher screen resolution. I've heard about using widths that use percentages and using iframes and things like that.
What's the best way to have one website fits all resolutions?
Im also wondering is there a way I can resize the image upon upload if so, how? And as this is a save as in my fileupload control will this overwrite any folder that has the userid already there? (what I want and need)
I have aspxcombobox. There are so many items with different lengths. If i select Small ones the combobox width is in minimum size and if i am selecting larger length item combobox width is increasing to fit the item in it. any property to set the combobox width constant for any item.
I have an Asp.Net website which should have a variable as a string in the url.
The content of the website changes depending on the year. the idea is to have this year in the url in a clean way.
http://localhost/YEAR/index.aspx
I have done this in MVC with routing, but i have no idea how to do it in asp.net I basically need just 1 route I guess. so all URL's will be as they were before (index.aspx, ...) basically in stead of having ?year=2011 behind EVERY url in the website i'd like to have this value in the route.
I am iterating through a dictionay object. And although I added a couple of keys @Microdoft and @Microsoft_Child which I thought were different but when i use the .ContainsKey method it views them as being the same. Should I use ContainsValue method?
Everytime I compile my asp .net project it states the following:
'Sessions' does not contain a definition for 'Select'.
In the page this happens on if I change something put it back and save and re-compile it tends to go ok, but at the moment it is happening every time. It does contain a definition for Select I can type it in plus the page does not show an error where this code is and works when it does compile ok?
I am trying to place a right-click menu addin for the asp.net html window.The one I currently have works on the C#/Vb code window...just not in the html code window.
That would get me the context menu (right-click menu) of the non-html code window.But what constant name would get me the html code window context menu?
I am building a website that have a number of dropdownlists. The user selects his/her choice and this is sent to a number of companies. Therefore the choice has to be changed to the corresponding value of the individual company i.e value 1 will be coverted to the corresponding value of "AB" for company "x". What way would be most efficent to achieve this. A database seems to be unefficent with the calls to the database. Would a 2-D array in a class be best?
My website application is developed with Visual Studio 2008. The programming is written and tested with a project saved on my local hard drive. Afterwards the program is transferred to my http site with the Copy Web Site function of VS 2008. Previously Visual Studio always knew the location of the remote web site. It always started the Copy Web Site function with my source site as the http site and the remote site as the site on my hard drive.
Recently, Visual Studio demands that I enter the remote site. Of course, I can do this and cause the Copy Web Site function to work. However, when VS knew the remote web site, it could easily notify me as to what changes had occurred on the Remote site since the last Copy Web site function. This helped me in determining which files needed to be copied to the http Source web site. How can I permanently link my hard drive file location as the source site in the Copy Web site function of Visual Studio 2008?
