C# - Setting A Textbox Text In Usercontrol From Page?
Jan 25, 2011
I have a usercontrol which contains a textbox. I now want to add variable to that user control, lets call it Text, which will populate the textbox with the value passed in. I thought this could be done in the "set" of the variable in the code behind of the user control.
public string Text
{
get {}
set
{
txtBox.Text = value;
}
}
txtBox is the ID of the textbox within the usercontrol. Does anyone know how this can be done?
Edit The problem I suspect is that I am setting the text value in the Page_Load of the page hosting the user control. Where should I be setting this value?
In set the Send button as default button in my page. In the button click event I try to set the focus to the TextBox. When clicking the button the event work fine but While clicking the enter button I cant input text to TextBox.
i have created a usercontrol that get some input from the user in the textbox. now i want to get that value in my page containing the same user control.
In my markup, in addition to a number of other controls I have the following:
<%:Html.TextBoxFor( m => m.UserName)%>
I'd like to be able to set the focus to this textbox when the page is loaded. Is there a really easy way to do this? I have to admit that so far I haven't found it. I know that I can do this using something like this JQuery/Javascript code: $('#UserName').focus();
However, I don't like the fact that the model field name 'UserName' has to be expressed as a string constant again here - it smells of a maintenance problem. I'd really like to be able to reference the model field directly if possible. Somethiing like this: $('#' + '<%:Html.ModelFieldNameFor(m => m.UserName)%>').focus();
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 am trying to set the focus to the user name TextBox which is inside an ASP.NET Login control.
I have tried to do this a couple of ways but none seem to be working. The page is loading but not going to the control.
Here is the code I've tried.
SetFocus(this.loginForm.FindControl("UserName")); And TextBox tbox = (TextBox)this.loginForm.FindControl("UserName"); if (tbox != null) { tbox.Focus(); } // if
I have a GridView (inside an update panel) that has header text that changes based on some user profile information. I set the header text in the Page_Load function of the page - that works fine. The problem is that when I change to the page number of the GridView, the header text is not redrawn. I am handling the OnPageChanging event to try to update the header text but nothing is happening. I've attached the relevant code.
MyUserControl.ascx is being used in Content.aspx and is being added programatically. The content page is using MyMaster.Master
MyMaster.Master has a variable which I can access from Content.aspx as I have the @MasterType directive set. What I am wanting to do is the following:
1) Set a value in MyUserControl.ascx
2) Access value from Content.aspx
3) Set value in MyMaster.Master
Step 2 is implemented in the PageLoad of content.aspx as follows:
Control ucControl= LoadControl("/UserControls/MyUserControl.ascx"); UserControls_MyUserControl myUC = ucControl as UserControls_MyUserControl; [code]....
The PreRender handler just sets a value in MyMaster.Master to true. In MyMaster.Master I check that value in PageLoad and try display something if it is true. This does not work.I suspect it has something to do with the Page Lifecycle, but I cannot seem to find which part is wrong.
I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.
I have a couple of tables in my DB that contain stored procedure names, control names, control types, SqlDbTypes, etc.... that correlate with DataEntryUC.
How do I reference a text box that is on DataEntryUC from NavSaveUC?
I have been working on the following code from NavSaveUC with no luck.
Dim MyControlName = "txtFirstName" Dim MyControlType = "TextBox" Dim MyStringValue as String Dim tmpTxtControl as TextBox Dim tmpDdlControl as DropDownList Select Case MyControlType Case "TextBox" tmpTxtControl = CType(Page.FindControl(MyControlName, TextBox) MyStringValue = tmpTxtControl.Text Case "DropDownList" tmpDdlControl = CType(Page.FindControl(MyControlName, DropDownList) MyStringValue = tmpDdlControl.SelectedValue End Select
I have a user control in asp.net that i need to dynmically set properties for. The propety and property values are in a dictionary, for example:
Dictionary<string, string> propertyValues; Control c = Page.LoadControl("~/Control.ascx")
I can currently set the properties on the control using reflection, however, with .net 4 and the new dynamic keyword, is there an easier way to do it, for example, something like this:
public DateTime fromdate { get; set; } public DateTime toDate { get; set; }
I am setting this values in my code behind. After setting the values i want to reload the usercontrol so that it fires a get method which will use these dates ...how will i reload the usercontrol
Property3 and Property4 anre both public properties of the page I am on and the user control
Currently the code complaing about Property3 saying it cannot create an object of Int32 from '<%=Property3%>' and Property4 always gets set to 0 (the default)
I do not wish to use the c# code to set these values as this Plugin will be deployed with a CMS which I have no control over
This textbox gets shown if a certain selection is made in a drop down. The problem is that I would like the "%" character to also be hidden or shown with the textbox.
I have tried putting the whole textbox control inside a DIVand in my JQuery hiding the DIV at the same time I hid the textbox.
I have a textbox which can be left blank or contain a date. If the textbox has a date I want the 2nd textbox's value to be set to the value of a session variable. I need this to happen before the update sql is performed on postback.
This is the code I have. But the textbox is coming back as nothing. Whether it has a value in it or not.
i have some textboxes in my parent page and a search button. when the search button is clicked, my modalpopup pops up. after chosing (clicking on the select button of the row) an entry from a gridview within my modalpopup (each row in the gridview has a buttonField), the rowCommand_Event fires... within this event i try to set the .Text property of some textboxes within the page containing my modalpopupExtender... i get no exceptions, but the textboxes are not set...
well i have a main page in which i have a grid with templete (textbox "maintxt"and a button)and a pop up in which i have a textbox"popuptxt" i want when ever i click the button of every row i can see the maintxt text in popuptxt i can edit it in popup and then by closing popup the text of maintxt update
I have a .ascx file residing in another page which has a button on it. On click I run a select statement that accesses the textbox for a value.
However, it keeps returning a Null Exception Error. I am trying access the textbox and its text through
[Code]....
I also tried -[Code]....
I also tried -[Code]....
But none of them work. Please can someone advise me how I find the textbox and then access its text?I have looked round the forums / google and cant find a way of doing this!
I can't seem to find a textbox using FindControl. The textbox is located inside an asp:Table, asp:Table is inside a UserControl and I load the usercontrol into the parent page.
<telerik:RadTextBox ID="txtRedemptionBeforeMessage" Text='<%#Bind("RedemptionBeforeMessage") %>' runat="server" /> protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e) if (e.Item is GridEditFormItem && e.Item.IsInEditMode) if (e.Item.OwnerTableView.IsItemInserted) [code]...
how to I get a default message to work - I suspect I need to look at an event after the bind.The Bind is in there because the same form code is used to edit.
I have what I think is a weird issue. I send text from one page to another via Session Variable. When page 2 loads, the text box has the session text set, but if the user changes the text and clicks the button, the SQL database is update with the original session text. If I remove the redirect from the page 2 button_Click method, then, the page refreshes with the textbox reverting to the session text and thr SQLDataSource has the session text added to it.
