How do I access the Control (dropdownlist) in current Page from the UserControl? In the UserControl:
String test = ((DropDownList)this.Parent.FindControl("drpdwnlstMainRegion")).SelectedValue;
or
String test = ((DropDownList)this.Page.FindControl("drpdwnlstMainRegion")).SelectedValue;
It return null on ((DropDownList)this.Parent.FindControl("drpdwnlstMainRegion")) for some reason? BTW ... I am using ASP.NET C# 3.5.
i have 2 textbox controls inside a usercontrol TextBoxUC.ascx i have a page.aspx that contains the usercontrol. how can i get a reference to each textbox using javascript from page.aspx?
I have a javascript embedded in my extended gridview control that reference the grid control. Example:

HTML code:

way to determine the gridview object in javascript. I want to make it generic so that if I use this gridview in any other control it should work instead of hardcoding the name.
I have a scenario where I have a tabstrip on the page and each tabstrip has a usercontrol. On page load i want to display the first tab and based on certain properties on that tab i want to enable or disable other tabs. Can somebody guide me on how to do this. I am unable to access the tabstrip control on the parent page from within the usercontrol.
I stored a object in viewstate on Page. Now when i access the same viewsate object on usercontrol,it shows as null. I even tried creating the same viewstate with same name in usercontrol and page.Both holds different value. I understand that viewstate is a protected property. How does this thing implement in above scenerio or is there any other reason for this behaviour.
Edit:
Usercontrol is there in the page markup. I am not loading it dynamically. I have a page EditFacilityworkType.aspx. On page I have a usercontrol FacilityWorkTypeDetails.aspx(FacilityWorkTypeDetails1). Inside this usercontrol i have a user control Workflow.aspx(Workflow1)
Page_Load() of Page I am retrieving workflowdetails on page_load() of page.
FacilityWorktype facilityWorkType = facilityDetails.GetFacilityWorktypeDetail(SessionHelper.FacilityWorkTypeID); ViewState["WorkFlow"] = facilityWorkType.FacilityWorkTypeWorkFlow Inside usercontrol FacilityWorkTypeDetails.aspx. I have a property public FacilityWorktype FacilityWorkTypeDetails { get { #region Fill FacilityWorktype return GetEntityFromControl(); #endregion } set { PopulateControls(value); } }
Now i set this property in page load of page
FacilityWorkTypeDetails1.FacilityWorkTypeDetails = facilityWorkType; Inside Workflow.aspx, I have a property /// <summary> /// Property to fill entity object from controls on this page /// </summary> public WorkFlow WorkFlowDetails { get { return GetEntityFromControls(); } set { BindTranscriptionMethodDDL(ddlTranscMethod); PopulateControls(value); } } Now PopulateControls() of FacilityWorkTypeDetails1, i am setting property of workflow1 private void PopulateControls(FacilityWorktype value) { Workflow1.WorkFlowDetails = value.FacilityWorkTypeWorkFlow; }
Now when i am retrieving values from
private WorkFlow GetEntityFromControls() { WorkFlow workFlow = (ViewState["WorkFlow"] as WorkFlow) ?? new WorkFlow(); //workFlow is null }
So now inside this function workFlow is null. I want to ask,why is it null when i have set viewstate in page.
I've created user control named test.ascs with one textbox. Now I added this user control in my default.aspx page. How can i access that textbox value from my default.aspx page?
I have a usercontrol on the content page. I'm trying to access this usercontrol's hiddenfield.
I was able to access it before applying the master Page. But once I changed the page to a content page , the value in the hiddenfield is showing empty.
alert(document.getElementById('<%=hidLat.clientID%>').value) is showing the value.
I have a property PickupHidLat defined on the ascx page and I'm using this property to access hidLat value on the content page.
I have several usercontrols which are loaded based on business logic.However, all of them have webcontrols whose selected/entered value needs to be accessible in parent page on an event.Since there can be any combination of UserControls, I do not want to load all the UserControls in the Parent Page, since they are heavy.
I would like to load only those controls which are supposed to appear on the page, yet access the value from the usercontrol which caused the postback. (I would rather not access using Request.Form) (ViewState is open, but unsuccessful to store value in parent page's viewstate in onClick)Here is a sample scenario
Page: Home
Dynamically Loads: UserControls1
UserControls has TextBox tb and Button btn, causing onClick
When btn is clicked, I want to get value of tb in parent page on PostBack, Page creates UserControl2
I am loading a control to a page dynamically with LoadControl("src to file"). In the usercontrol i have a validator and some other controls that i would like to access from my page. I canät get it to work, null pointer exception. Scenario is like this. I have a Edit.aspx page which loads the EditTemplate.ascx usercontroll. I would like to get information or find the controls in the EditTemplate from the Edit.aspx site. I have tried exposing the controls and validators as properties but how do i access them from my Edit.aspx?
Example code: Edit.aspx, the control is later added into a Control control = LoadControl("src to ascx"); TemplatePlaceHolder.Controls.Add(control); EditTemplate.ascx <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="CompanyImageFile" ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator> CodeBehind public partial class EditTemplate : System.Web.UI.UserControl, IEditTemplate { public RequiredFieldValidator Validator { get { return this.RequiredFieldValidator1; } set { this.RequiredFieldValidator1 = value; } }
From the Edit.aspx site i would like to check the validators isValid property. Isvalid is set in a Save method. The save button that saves the template is located in edit.aspx, so the post in done from that page. So the question is how to get a hold of the property from the usercontrol in the edit.aspx page, where and how should this be done?
If for example my userControl has a CheckBox called IsGreatCoder and the userControl is embedded in a main page (parent page).
I normally have gained access to the IsGreatCoder.Checked value in the main-page by exposing it through a public property that I have to manually write (say "IsAGreatCoder").
If UserControl is included in the main page as "userControl1", then I would access it as "userControl1.IsAGreatCoder".
But, I was wondering if there was anyway to declare the UserControl such that all the UI controls added to it were declared as being public, that way allowing me to gain access to the actual controls in the main page (the parent).
Essentially I would like to be able do something like userControl1.IsGreatCoder.Checked instead of having to implement a property.
The reason I want to do this is that I want to have access to many more of the check-box's properties and it would be a pain to implement each one as a public property.
I have a user control with a textbox. I am loading it at runtime on parent page with code behind.After click of button on a parent page i need the text of that usercontrol's textbox.
I tried with following code but it does not work for me
myusercontrol us = new myusercontrol(); TextBox textbox = (TextBox)us.FindControl("txtusercontrol"); string str = textbox.Text.ToString();
I have created a user control UserVote that has property to find total vote on particular question. Now I want to call it from an aspx page.The control code-behind (UserVote.ascx.cs) looks like:
public partial class UserVote : System.Web.UI.UserControl { protected void Page_Load(object sender, EventArgs e) { DataTable dtVoteInfo = ShowVoteDetail(objectType, objectId); if (dtVoteInfo != null) { if (dtVoteInfo.Rows.Count > 0) { int.TryParse(dtVoteInfo.Rows[0]["TOTAL_VOTE"].ToString(), out currentVote); int.TryParse(dtVoteInfo.Rows[0]["MY_VOTING"].ToString(), out myVoting); } } ltrVotes.Text = currentVote.ToString(); hfCurrentVote.Value = currentVote.ToString(); hfMyVote.Value = myVoting.ToString(); // ...snipped for brevity... } }

Does any know why I can't access the my custom user control StatusBar which is declared inside a masterPage?
In the ContentPage, I tried referencing the control this way "this.Site.stastusBar" and "this.Master.Status" and neither one works. Both instellisense warns me that "statusBar" does not exist.
on master page, i have declared a label control & set value to it.now on content page, i m able to find the control, but the value is alwasy null & not the one which was set.when i debugged, content page's load event is called first, after that the master page is called.so where should i access the master page control so that i get the set value.
