Forms Data Controls :: Cannot Repopulate / Filter Datagrid With User Entered Value From Text Box
Feb 18, 2011
I have a Datagrid control which is populated with data from an Access database when the page loads - a simple 'Select *' command. This page also contains a text box and a button, the idea being that the user can then filter the data by entering a value in the text box and clicking on the button to pass the new parameter to the datasource.
However, I cannot get this to work, I know it has something to do with 'IsPostback', but I am at a loss. I have tried variations of the following in the code behind page but to no avail.
I know how to handle the filtering of the grid (create a criteria and set to rowfilter of the dataview) But, I dont know how to get the value of the column of the selected row.
I dont know whether this simple task or not, but I tried to search in google but couldn't find anything.
I've a asp.net form and user enters some data in the text boxes provided. Whenever user submits the form, browser will save that form data. I don't want this form data to be saved in browser. How can I restrict the browser saving this form data without touching the browser settings?
Application is developed using asp.net and normal text boxes are used here.
I have done this with a DropDownList but not 2 text boxes that require date info.
With the DropDownList once a itme is selected from the list the GridView gathers the data in a SQL query and displays it in the same page
I want to have the same type of response when the user enters date data in two text boxes. It would be nice that when they exit the 2nd parameter box to show the grid.
Not sure how to do that in SelectParameters and convert the text data to a date.
I am going to use RequiredFieldValidtors but I am not sure what to do to make sure a valid date is entered.
I have an ASP.Net UpdatePanel that updates on a timer. Within the UpdatePanel and nested in a GridView, I have a TextBox that the user enters a value in with a submit button. Everything works fine, except if the user does not submit the value before the timed interval, the text is removed from the TextBox. Is there a way to persist the user entry into the TextBox between updates? Is there a better way of doing this?
I am developing a page where i have a grid in content page (inherited from master page) which i am populating using DATASET in code behind like this here is the aspx.

As you can see i have some bound fields and one template field called "txtValue" which is the only input in gridview. Now what i want is when user input the value it should check the FACEVALUE and see if the entered value is not above the FACEVALUE and then need to Input value - FACEVALUE and result should be displayed in REMAINING field which is also a template field as label control.
basically I am try to replicate a filtered list like this;

but I need it to work on an asp.net, and rather than having to hit a button to load an xml data file I need the data to be initialised when the page loads and get the data from a SQL Server database.
I'm trying to create a Formview in ASP.net 3.5. The underlying SQL Server table does not have an identity field based Primary Key. The primary key is a 4 character user entered field. I have created the form and all looks good but I get the following error message when I try to insert a record
Could not find a row that matches the given keys in the original values stored in ViewState. Ensure that the 'keys' dictionary contains unique key values that correspond to a row returned from the previous Select operation.
I thought ViewState was supposed to resolve the issue. I have viewstate enabled on the page and the formview but that doesn't seem to make a difference.
How can I create a form view with a user-entered text field as the primary key and get the b.... thing to work?
I had called the data from query to data table and now i have a gridview in which i am using one datalist and 2 text boxes and and reming coloumns are bounded iahve to assiaign them values which datatable have either null or any value.
I want to be able to take data entered in a certain text box in a web form and use it in another web form for example: upon clicking a button I want to redirect to another web form and that a text present in the first web form box textbox will automatically appear in a text box on the second web form can someone get me started on how to do that?
I have a list box with data coming from the database. Above the list box I have a text box. If the user enters some text in the text box,then the data in the list box should be filtered as per the content entered in the textbox. In my page, i have about 7-8 such similar textboxes and listboxes. So I want to implement a common function which can be used for all the text boxes in the page. I tried to achieve this in textchanged event and javascript but sometimes not working. Is there any other simple way except javascript? Is it efficient to use java script in this scenario? Need your valuable inputs.
i want to display a multiline text in a datagrid i insert the text in a textbox outside the datagrid.
the textbox wraps the text if it doesnt fit to the textbox length.then i push a button and insert that text in a database. then i want to display this text in a datagrid.i use two options in a label or in a textbox in a templatecolumn but with the textbox <asp:textbox ID="textbox1" runat="server" style="overflow:hidden" Font-Size="15px" BackColor="#FFFFC0" TextMode="multiline" Width="750px" Wrap="true" borderstyle="None" BorderWidth="0" Text='<%# Databinder.Eval(Container.Dataitem,"text_caption") %>'></asp:textbox>
i receive only the first two lines
and with the label <asp:Label ID="Label112" runat="server" BorderStyle="None" Width="750px" BorderWidth="0" Text=' <%# Databinder.Eval(Container.Dataitem,"text_caption") .ToString.Replace(chr(13),"<br />") & "<br/>" & "<br/>" %>' ></asp:Label>
if the text is too big without an enter(that text wraps in the outside inserting textbox) then the datagrid width becomes too big although the text is diplayed normal with new lines so in the datagrid i have much space without characters the textbox that i use to insert new text is here <asp:TextBox D="tbox_text_caption" runat="server" Height="232px" Style="left: 400px; position: absolute; top: 8px" MaxLength="750" TextMode="MultiLine" Width="752px" Wrap="true" TabIndex="5" BackColor="#FFE0C0"></asp:TextBox>
I am editing the page links text 1 2 3 4 5 ... as 1-10 11-20 21-30 31-40 ...succesfully. But here the problem is when am clicking 21-30 link it changes to 3. How to display the 3 as 21-30.
I have a FormView and the SELECT statement I have is as follows:
SelectCommand="SELECT [UserName], [Full_Name_1], [Full_Name_2], [Email], [Address], [City], [State], [Zip_Code], [Home_Phone], [Cell_Phone] FROM [Homeowners] WHERE ([UserName]='<%$ User.Identity.Name %>')"... but it results in the FormView disappearing from the web page. Note: at the top of the page, <%= user.identity.name %> displays the name fine, so user.identity.name does contain the info I'm looking for.I am trying to figure out how to correctly format the SELECT filter to feed user.identity.name to the SELECT statement as a filter. ... or if there is an alternative way.
I have a form where users enter information in a multi-line text box. This could be anything, such as bullets, carriage return line feeds, etc. Think of anything that you might copy and paste into a multi-line text box from Word Pad, or Word. I then store this information into a SQL Server NText field.When I retreive this information, I need to display it as the user entered it into the text box field into a Literal or Label control (or something else if there is a better alternative) to display it. Problem is that when I display this text into the Text property of a Literal control everything is jumbled and all characters (bullets) are lost, no carriage returns, etc. One big mush of stuff. If I display this information in the Text property of Label control, I get the bullet characters, but no carriage returns
After hitting the insert button the insert stored proc is run. if the record already exists then stored proc returns a specific value.I need to refill the details view textboxes with the values the user typed in.I am using the ItemInserted event handler.I seem to reference the control okay but the text doesn't change...even when I replace the command.parameter to just a literal text like "test".
TextBox tNPA = DetailsView1.FindControl("InsertName") as TextBox; tNPA.Text = command.Parameters[0].Value.ToString();
So what am I missing. I also tried a detailsview1.databind() before and then tried after the above line and still no luck.
