C# - No Change For Index Of DropDownList In A Custom Control?

Jun 15, 2010

I have Created A Custom Control which is a DropDownList with specified Items. I designed AutoPostback and SelectedCategoryId as Properties and SelectedIndexChanged as Event for My Custom Control. Here Is My ASCX file Behind Code:

private int _selectedCategoryId;
private bool _autoPostback = false;
public event EventHandler SelectedIndexChanged;
public void BindData()

[Code]....

But Always The Selected Index of CategoryDDL1 is 0(Like default). this means Only Zero Value will pass to the event to update textboxes Data. what is the wrong with my code? why the selected Index not Changing?

Forms Data Controls :: How To Capture A DropDownList Selected Index Change Event

Sep 15, 2010

I have a gridview that receives data based on selection from a primary dropdownlist object. Works.

Within the gridview, there is a dropdownlist whose selected index is based on the query from the primary dropdownlist. Works.

Problem.

How do I force the used to change whatever value that the dropdownlist contains after they make their initial selection from the primary dropdownlist; except the default value of "make a selection".

Gridview, contains a checkbox which drives whether a selected row is inserted into the data base. The databind in done using an ObjectDataSource on the presentation page, not in the code behind.

I seriously want to learn how to create a custom server control, for that I made a requirement for myself, but lost on how to accomplish it.
Requirement -I want to create a cascading dropdownlist control - which should have following properties -1) ConnectionString - used to get data for the 1st dropdown from database, and also it is used by 2nd DropDown to get data.2) 1stSelectCommand - Used by the 1st DropDown to get data from the database.3) 2ndWhereCommand - used by the 2nd DropDown - uses the selected value from the 1st DropDown in the where clause to get data.
Methods - 1) DropDown1_SelectedIndexChanged()2) DropDown2_SelectedIndexChanged(3) CustomCascading_Changed() - this happens when any of the DropDowns index changed.

Web Forms :: Preserve DropDownList Selected Index In User Control?

Dec 4, 2010

I have a user control that has some drop down lists. These DDLs are used by the user to filter their product search on my search page. A button is used to post the form and get the results of the product search. Those results are displayed on the results page, which also has the search filter user control on it. I'd like the results page to have the values of the DDLs be preserved from the search page. Example: user selected color of red and size of large on the search page. When the results page is displayed, I'd like the selected color to be red for the color DDL and the size to be large for the size DDL. How can I do this?

C# - Change Login Control Layout In Custom Control?

Jun 21, 2010

Is it possible to create a Custom Control which inherits from System.Web.UI.WebControls.Login and change its layout and add additional controls such as a DropDownList. I have tried various ways to do this by overriding the Render Contents methods but each time I have to recreate the controls which are already present in the main Login control. Is it possible to somehow get a reference to the controls in the parent class and then override the Render Contents method to render the controls how I need them?I would like if at all possible to use the controls and functionality that already exist in the Login control but just change the layout and add in an additional DropDownList control.

C# - Add A Validation Support To DropDownList By Creating A Custom Control?

Feb 2, 2011

I'm trying to add a validation support to DropDownList by creating a custom control inheriting from DropDownList:

public class MyDropDown: DropDownList, INamingContainer
{
private const string ValidatorID = "Validator";
private RequiredFieldValidator _validator;

[Code]....

My class implements INamingContainer because I wanted to avoid naming conflicts. Unfortunately when I try using this control I get the following exception:

Unable to find control id 'MDD' referenced by the 'ControlToValidate' property of 'MDD_Validator'

This is happening beause for INamingContainer FindControl(NamingContainerId) returns null.

When I remove INamingContainer implementation and set validator ID in the following way:

_validator.ID = String.Format("{0}_{1}", ID, ValidatorID);

Everything is working fine, and id given to Validator is the same as it would be inside Naming container.

But is there a way to accomplish this WITH INamingContainer ?

VS 2010 - Dropdownlist Getting Index

Feb 13, 2013

I've made a small site which purpose is to allow people to add members to their clan. The page has a dropdown list with the names of all available clans.

The name of the clans and the clan password come from a text file which is read when loading the page (but not when there's a page postback) and adds the clans to the dropdownlist.

The clan name and clan password are also read into an array for later use.

When the user selects an item in the dropdownlist I want to get the index so I know which clan name to use and which password.

I tried getting the index by using the indexchanged event and also just the click event of a button but somehow this doesn't seem to be working properly.

When the user filled in all fields and hits the submit button I want to check if the password is correct and want to know the clanname. I'm trying to do this by using the array's with that data and setting the item of the array equal to the index of the selected item in the dropdownlist.

But when I press the button I keep getting a wrong password error even though it's correct. If I remove the password check and submit it then the form should create or append to a text file with the name of the clan. But when submitted the text files is .txt instead of clanname.txt.

Tried setting the dropdown to autopost back or without and get the same result.

My code is the following:

reading the data into the array + adding the clannames to the dropdownlist

vb Code:
Dim data() As String    Dim clanname(50) As String   
Dim clanpass(50) As String Protected Sub Page_Load(sender As Object, e As System.EventArgs)
Handles Me.Load        
Dim fileName As String = "C:/ClientSites/data/clans.txt"       

[Code] ....

The submit button code

vb Code:
Protected Sub btnSubmit_Click(sender As Object, e As System.EventArgs) Handles btnSubmit.Click        
naam = txtMemberName.Text.ToString        gamertag = txtGamerTag.Text.ToString       
platform = txtPlatform.Text.ToString         index = DropDownList1.SelectedIndex        
paswoord = clanpass(index)                    

[Code] ....

In short I load in data from a file into two arrays, clanpass and clanname. Populate the dropdown with the clannames. Then upon submitting I want to check the password against the password for the selected item by using it's index. I also want the name to write it to the correct text file.

C# - Add Reference To Method In Custom Control To A Child Control Created In That Same Custom Control

Feb 3, 2010

I have a custom control that is based off the gridview control located at: here The control is basically a gridview that automatically creates a column of checkboxes that can be used to "check" individual rows in the gridview. During the gridview's "CreateColumns" event, the "checkboxcolumn" is created dynamically. The checkboxcolumn also contains another checkbox in the header that is used to "select/deselect all" checkboxes in the column. Since the gridview does not automatically remember the state of the checkboxes in the checkboxcolumn on postback, I added a method to the control called "SaveCheckBoxState" which stores the indexes of the checked rows in Viewstate, and then I modified the "OnRowDataBound" event to check the Viewstate and reset the checkboxes based on the Viewstate.

I then added a call to "SaveCheckBoxState" in the gridview's OnSorting and OnPageIndexChanging events. This works great so long as I'm sorting or changing pages. However, I need it to update the viewstate everytime someone clicks or unclicks one of the checkboxes. At this time, the checkboxes are rendered with an onclick event that calls some javascript to highlight the row, or in the case of the checkbox in the header, to select/deselect all checkboxes. I need to call the "SaveCheckBoxState" method from the javascript used by the customcontrol, or I need to find a way to modify viewstate from javascript and perform the same action as "SaveCheckBoxState".

I've tried adding the "SaveCheckBoxState" to the onclick event declaration in the checkboxes, but when run, it simply tells me that the method is undefined. It doesn't exist in the parent page, and I don't think I should have to make an event for the parent page to pass the click to. It seems to me this should be all self contained within the custom control. Does anyone know how I can acheive this? Here is the code for the gridview OnPreRender event where the onclick event of the checkbox is set:

protected override void OnPreRender(EventArgs e)
{
// Do as usual
base.OnPreRender(e);
// Adjust each data row
foreach (GridViewRow r in Rows)
{
// Get the appropriate style object for the row
TableItemStyle style = GetRowStyleFromState(r.RowState);
// Retrieve the reference to the checkbox
CheckBox cb = (CheckBox)r.FindControl(InputCheckBoxField.CheckBoxID);
// Build the ID of the checkbox in the header
string headerCheckBoxID = String.Format(CheckBoxColumHeaderID, ClientID);
// Add script code to enable selection
cb.Attributes["onclick"] = String.Format("ApplyStyle(this, '{0}', '{1}', '{2}')",
SelectedRowStyle.CssClass,
style.CssClass,
headerCheckBoxID);
// Update the style of the checkbox if checked
if (cb.Checked)
{
r.BackColor = SelectedRowStyle.BackColor;
r.ForeColor = SelectedRowStyle.ForeColor;
r.Font.Bold = SelectedRowStyle.Font.Bold;
}
else
{
r.BackColor = style.BackColor;
r.ForeColor = style.ForeColor;
r.Font.Bold = style.Font.Bold;
}
}
}
