search string text in search grid is not working using send keys

Question

I am passing sendKeys( ) through search grid to search a particular string.I am able to click that search text but its not clicking the search string ,Below is the html for that search text:

<input  name="ctl00$ContentPlaceHolder1$txtSessionName"
        type="text"
        onchange="javascript:setTimeout('__doPostBack(\'ctl00$ContentPlaceHolder1$txtSessionName\',\'\')', 0)"
        onkeypress="if (WebForm_TextBoxKeyHandler(event) == false) return false;"
        id="ContentPlaceHolder1_txtSessionName"
        class="search-icon"
        placeholder="Session Title/Track Name"
        onkeyup="ShowSearch();"
        title="Session Name"
        autocomplete="off"
        style="width: 300px;">

I used with below code but not working:

First try

driver.findElement(By.name("ctl00$ContentPlaceHolder1$txtSessionName").sendKeys(searchSessionText);

Second try

WebELment= driver.findElement(By.name("ctl00$ContentPlaceHolder1$txtSessionName"));
JavascriptExecutor rightexecutor = (JavascriptExecutor)driver;
rightexecutor.executeScript("arguments[0].setAttribute('value','searchSessionText')", Element);

Third try:

WebElement
Element=driver.findElement(By.name("ctl00$ContentPlaceHolder1$txtSessionName"));
Actions builder = new Actions(driver);
builder.moveToElement(Element).sendKeys(searchSessionText).build().perform();

Fourth try:

WebElement
Element=driver.findElement(DesignerLocators.EmailTemplateEditorTemplateName);
Actions builder = new Actions(driver);
builder.moveToElement(Element).click().sendKeys(searchSessionText).build().perform();

Fifth try

WebElement Element=driver.findElement(DesignerLocators.EmailTemplateEditorTemplateName);
Actions builder = new Actions(driver);
builder.moveToElement(Element).click(Element).sendKeys(searchSessionText).build().perform();

Please suggest.
